Patent Application
20230166501
The present application is based on, and claims priority from JP Application Serial Number 2021-193119, filed Nov. 29, 2021, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to an ink jet system.
An ink jet printer normally discharges ink from a head on a medium by driving a drive element such as a piezoelectric element. For example, JP-A-2011-121208 discloses that the number of times of scanning for a unit region on a medium is varied (one pass/a plurality of passes) according to the amount of ink applied per unit region on the medium.
In recent years, there is a business model in which a head manufacturer manufactures and sells a head to a printer manufacturer. Printers have various applications and demands. In the above business model, the head manufacturer provides the head to the printer manufacturer in cooperation with the printer manufacturer who has specialized knowledge for each application and each demand. The printer manufacturer utilizes the above-described specialized knowledge to manufacture a printer incorporating the head of the head manufacturer. This is because there are cases where the above business model is more efficient in terms of comprehensively satisfying various applications and demands than the head manufacturer manufactures printers that satisfy various applications and demands one by one.
However, in the above business model, the printer manufacturer is required to search for and determine a scanning condition such as an optimum number of times of scanning and a scanning direction. Depending on the printer manufacturer, there are cases where there is specialized knowledge for each application and each demand, but there is not much knowledge about the printer itself, and in that case, this search and determination takes a huge amount of time and cost.
On the other hand, especially when the head manufacturer has knowledge about the printer, it is conceivable that the head manufacturer provides appropriate information on the scanning condition to the printer manufacturer. However, due to the nature of the above-described business model that the head manufacturer and the printer manufacturer are different, it is unclear on the head manufacturer side how the printer manufacturer sets the usage conditions of ink, medium, head, and the like. Since the optimum scanning condition differs according to these usage conditions, it was difficult for the head manufacturer to provide the appropriate information on the scanning condition. Therefore, the printer manufacturer is required to search for the information on the scanning condition by himself or herself according to each usage condition, and in some cases, the burden on the printer manufacturer may increase.
According to an aspect of the present disclosure, there is provided an ink jet system including a head unit that includes a nozzle discharging ink, a pressure chamber communicating with the nozzle, and a drive element applying pressure fluctuation to the ink in the pressure chamber by supplying a drive pulse, an acquisition portion that acquires output information including one or both of first output information regarding the head unit and second output information regarding the ink used for the head unit, a first coupling portion that is communicably network-coupled to a server, a first output portion that outputs the output information to the server via the first coupling portion, a first input portion to which input information is input from the server via the first coupling portion, and a determination portion that determines the number of times of scanning or a scanning direction of the head unit with respect to a unit region on a medium based on the input information.
Hereinafter, preferred embodiments according to the present disclosure will be described with reference to the accompanying drawings. In the drawings, the dimensions and scale of each part are appropriately different from the actual ones, and some parts are schematically illustrated for easy understanding. In addition, the scope of the present disclosure is not limited to these forms unless it is stated in the following description that the present disclosure is particularly limited.

Each of the server 300 and the third processing device 400 is owned by the head manufacturer. Maintenance and management of the server 300 are performed by the head manufacturer.
When the user uses the printer main body, the user owns the ink discharge device 100_1, the first processing device 200_1, and the head unit 110.

The user refers to a person who uses the ink discharge device 100_1. For example, when a manufacturer of the printer main body who purchased a head from a head manufacturer and manufactured the printer main body uses the printer main body, the manufacturer of the printer main body is the user. In addition, for example, when a manufacturer of the printer main body purchases a head from a head manufacturer and manufactures a printer main body, and a third party purchases and uses the printer main body from the manufacturer of the printer main body, the third party is a user.

In the following, each of the ink discharge devices 100_1 to 100_3 may be referred to as an ink discharge device 100, without distinguishing the ink discharge devices 100_1 to 100_3. Each of the first processing devices 200_1 to 200_3 may be referred to as a first processing device 200, without distinguishing the first processing devices 200_1 to 200_3.
In the example illustrated in
The ink discharge device 100 is a serial type printer that prints an image based on the recorded data DP from the first processing device 200 on a medium by an ink jet method.

For example, various papers, various cloths, various films, and the like are included.
The ink discharge device 100 includes a head unit 110. The head unit 110 is a module including an ink jet head. In the following, among the elements constituting the ink discharge device 100, the elements other than the head unit 110 may be referred to as a “printer main body”. In addition, the head unit 110 or the ink discharge head 110a described later may be simply referred to as a “head”. The configuration of the ink discharge device 100 will be described in detail later with reference to
The first processing device 200 is a computer such as a desktop type or a notebook type, and has a function of generating recorded data DP, a function of controlling printing by the ink discharge device 100, and a function of determining the scanning condition used for the printing. The configuration of the first processing device 200 will be described in detail later with reference to
The first processing device 200 is communicably coupled to the server 300 via a communication network NW including the Internet. The first processing device 200 outputs output information D1 to the server 300 and inputs input information D2 from the server 300. The output information D1 is information including one or both of the information regarding the head unit 110 described later and the information regarding the ink used for the head unit 110. The input information D2 is information regarding the scanning condition of the print processing. The first processing device 200 determines the scanning condition of the print processing based on the input information D2. In addition, the first processing device 200 generates recorded data DP by image processing, for example, image data DI in a bitmap format such as JPEG or a vector system such as PostScript, portable document format (PDF), and XML paper specification (XPS). For example, the image processing includes color conversion processing, density correction processing, quantization processing, and distribution processing. In addition to the above-described processing, the image processing may include, for example, raster image processor (RIP) processing or the like, when necessary.
The server 300 is a computer that functions as a cloud server, and has a function of inputting output information D1 from the first processing device 200, a function of generating input information D2 based on the output information D1, and a function of outputting the generated input information D2 to the first processing device 200. The configuration of the server 300 will be described in detail later with reference to
In addition, the server 300 is communicably coupled to the third processing device 400, and appropriately transmits and receives information necessary for generating the input information D2. The third processing device 400 is a computer that inputs the output information D1 from the server 300, if necessary, and outputs the information necessary for generating the input information D2 to the server 300.
In the ink jet system 10 of the above outline, since the first processing device 200 outputs the output information D1 toward the server 300, the output information D1 can be provided to the head manufacturer. Therefore, by utilizing the knowledge of the head manufacturer in addition to the output information D1, the input information D2 can be efficiently obtained as the information necessary for determining the scanning condition of the print processing. Since the first processing device 200 determines the scanning condition of the print processing based on the input information D2 input from the server 300, the scanning condition of the print processing can be determined while reducing the burden on the printer manufacturer. Hereinafter, the ink jet system 10 will be described in detail.
The head unit 110 is an assembly including a head chip 111, a drive circuit 112, a power supply circuit 113, and a drive signal generation circuit 114.

In the example illustrated in
The drive circuit 112 switches whether or not to supply a drive signal Com output from the drive signal generation circuit 114 as a drive pulse PD for each of the plurality of drive elements 111f included in the head chip 111 under the control of the processing circuit 150. The drive circuit 112 includes, for example, a group of switches such as a transmission gate for the switching.
The power supply circuit 113 receives power from a commercial power source (not illustrated) and generates various predetermined potentials. The various generated potentials are appropriately supplied to each part of the ink discharge device 100. In the example illustrated in
The drive signal generation circuit 114 is a circuit that generates the drive signal Com for driving each drive element 111f included the head chip 111. Specifically, the drive signal generation circuit 114 includes, for example, a DA conversion circuit and an amplifier circuit. In the drive signal generation circuit 114, the DA conversion circuit converts a waveform designation signal dCom described later from the processing circuit 150 from a digital signal to an analog signal, and the amplifier circuit generates a drive signal Com by amplifying the analog signal using the power supply potential VHV from the power supply circuit 113. Here, among the waveforms included in the drive signal Com, the signal of the waveform actually supplied to the drive element 111f is the drive pulse PD.
The movement mechanism 120 changes the relative position of the head unit 110 and the medium. More specifically, since the ink discharge device 100 is a serial type, the movement mechanism 120 includes a transport mechanism that transports the medium in a predetermined direction, and a movement mechanism that repeatedly moves (scans) the head unit 110 along an axis orthogonal to the transport direction of the medium.
The communication device 130 is a circuit capable of communicating with the first processing device 200. For example, the communication device 130 is an interface such as a wireless or wired local area network (LAN) or a universal serial bus (USB). USB is a registered trademark.

In addition, the communication device 130 may be integrated with the processing circuit 150.
The storage circuit 140 stores various programs executed by the processing circuit 150 and various data such as recorded data DP processed by the processing circuit 150. The storage circuit 140 includes, for example, one or both semiconductor memories of one or more volatile memories such as a random access memory (RAM) and one or more non-volatile memories such as a read only memory (ROM), an electrically erasable programmable read-only memory (EEPROM) or a programmable ROM (PROM).

The waveform designation signal dCom is a digital signal for defining the waveform of the drive signal Com generated by the drive signal generation circuit 114.
As illustrated in
The head chip 111 has a configuration substantially symmetrical with each other in the direction along the X axis. However, the positions of the plurality of nozzles N in the first row L1 and the plurality of nozzles N in the second row L2 in the direction along the Y axis may be the same as or different from each other.
As illustrated in
The flow path substrate 111a and the pressure chamber substrate 111b are laminated in this order in the Z1 direction, and form a flow path for supplying ink to the plurality of nozzles N. The diaphragm 111e, a plurality of drive elements 111f, the protective plate 111g, the case 111h, and the wiring substrate 111i are installed in a region located in the Z1 direction with respect to a laminated body including the flow path substrate 111a and the pressure chamber substrate 111b. On the other hand, the nozzle plate 111c and the vibration absorber 111d are installed in the region located in the Z2 direction from the laminated body. Each element of the head chip 111 is approximately a plate-shaped member elongated in the Y direction, and is bonded to each other by, for example, an adhesive. Hereinafter, each element of the head chip 111 will be described in order.
The nozzle plate 111c is a plate-shaped member provided with the plurality of nozzles N in each of the first row L1 and the second row L2. Each of the plurality of nozzles N is a through-hole through which ink is passed. Here, the surface of the nozzle plate 111c facing the Z2 direction is a nozzle surface FN. The nozzle plate 111c is manufactured by processing a silicon single crystal substrate by a semiconductor manufacturing technique using a processing technique such as dry etching or wet etching, for example. However, other known methods and materials may be appropriately used for manufacturing the nozzle plate 111c. In addition, the cross-sectional shape of the nozzle is typically circular, but is not limited thereto, and may be a non-circular shape such as a polygon or an ellipse.
The flow path substrate 111a is provided with a space R1, a plurality of supply flow paths Ra, and a plurality of communication flow paths Na for each of the first row L1 and the second row L2. The space R1 is a long opening extending in the direction along the Y axis in a plan view in the direction along the Z axis. Each of the supply flow path Ra and the communication flow path Na is a through-hole formed for each nozzle N. Each supply flow path Ra communicates with the space R1.
The pressure chamber substrate 111b is a plate-shaped member provided with a plurality of pressure chambers C called cavities for each of the first row L1 and the second row L2. The plurality of pressure chambers C are arranged in the direction along the Y axis. Each pressure chamber C is a long space formed for each nozzle N and extending in a direction along the X axis in a plan view. Each of the flow path substrate 111a and the pressure chamber substrate 111b is manufactured by processing a silicon single crystal substrate by, for example, semiconductor manufacturing technique, in the same manner as the nozzle plate 111c described above. However, other known methods and materials may be appropriately used for the manufacture of each of the flow path substrate 111a and the pressure chamber substrate 111b.
The pressure chamber C is a space located between the flow path substrate 111a and the diaphragm 111e. For each of the first row L1 and the second row L2, the plurality of pressure chambers C are arranged in a direction along the Y axis. In addition, the pressure chamber C communicates with each of the communication flow path Na and the supply flow path Ra. Therefore, the pressure chamber C communicates with the nozzle N via the communication flow path Na and communicates with the space R1 via the supply flow path Ra.
The diaphragm 111e is disposed on the surface of the pressure chamber substrate 111b facing the Z1 direction. The diaphragm 111e is a plate-shaped member that can elastically vibrate. The diaphragm 111e includes, for example, a first layer and a second layer, which are laminated in the Z1 direction in this order. The first layer is, for example, an elastic film made of silicon oxide (SiO2). The elastic film is formed, for example, by thermally oxidizing one surface of the silicon single crystal substrate. The second layer is, for example, an insulating film made of zirconium oxide (ZrO2). The insulating film is formed by, for example, forming a zirconium layer by a sputtering method and thermally oxidizing the layer. The diaphragm 111e is not limited to the above-described configuration by laminating the first layer and the second layer, and may be configured to include, for example, a single layer or three or more layers.
On the surface of the diaphragm 111e facing the Z1 direction, the plurality of drive elements 111f corresponding to the nozzles N are disposed with each other for each of the first row L1 and the second row L2. Each drive element 111f is a passive element that is deformed by the supply of a drive signal. Each drive element 111f has a long shape extending in a direction along the X axis in a plan view. The plurality of drive elements 111f are arranged in a direction along the Y axis so as to correspond to the plurality of pressure chambers C. The drive element 111f overlaps the pressure chamber C in a plan view.
Each drive element 111f is a piezoelectric element, and although not illustrated, each drive element 111f includes a first electrode, a piezoelectric layer, and a second electrode, and these are laminated in the Z1 direction in this order. One electrode of the first electrode and the second electrode is an individual electrode disposed apart from each other for each drive element 111f, and the drive pulse PD is supplied to the one electrode. The other electrode of the first electrode and the second electrode is a band-shaped common electrode extending in the direction along the Y axis so as to be continuous over the plurality of drive elements 111f, and an offset potential VBS is supplied to the other electrode. Examples of the metal material of these electrodes include metal materials such as platinum (Pt), aluminum (Al), nickel (Ni), gold (Au), and copper (Cu), and among these metal materials, one type can be used alone or two or more types can be used in combination in an alloy or laminated manner. The piezoelectric layer is made of a piezoelectric material such as lead zirconate titanate (Pb(Zr,Ti)O3), and forms, for example, a strip extending in the direction along the Y axis so as to be continuous over the plurality of drive elements 111f. However, the piezoelectric layer may be integrated over the plurality of drive elements 111f. In this case, the piezoelectric layer is provided with a through-hole penetrating the piezoelectric layer and extending in a direction along the X axis in a region corresponding to a gap between pressure chambers C adjacent to each other in a plan view. When the diaphragm 111e vibrates in conjunction with the above deformation of the drive element 111f, the pressure in the pressure chamber C fluctuates, so that ink is discharged from the nozzle N.
The protective plate 111g is a plate-shaped member installed on the surface of the diaphragm 111e facing the Z1 direction, protects the plurality of drive elements 111f, and reinforces the mechanical strength of the diaphragm 111e. Here, the plurality of drive elements 111f are accommodated between the protective plate 111g and the diaphragm 111e. The protective plate 111g is made of, for example, a resin material.
The case 111h is a member for storing ink supplied to the plurality of pressure chambers C. The case 111h is made of, for example, a resin material. The case 111h is provided with a space R2 for each of the first row L1 and the second row L2. The space R2 is a space communicating with the above-described space R1 and functions as a reservoir R for storing ink supplied to the plurality of pressure chambers C together with the space R1. The case 111h is provided with an inlet IH for supplying ink to each reservoir R. The ink in each reservoir R is supplied to the pressure chamber C via each supply flow path Ra.
The vibration absorber 111d, also referred to as a compliance substrate, is a flexible resin film constituting the wall surface of the reservoir R, and absorbs pressure fluctuations of ink in the reservoir R. The vibration absorber 111d may be a thin plate made of metal and having flexibility. The surface of the vibration absorber 111d facing the Z1 direction is bonded to the flow path substrate 111a with an adhesive or the like.
The wiring substrate 111i is mounted on the surface of the diaphragm 111e facing the Z1 direction, and is a mounting component for electrically coupling the head chip 111, the drive circuit 112, the control module 110b, and the like. The wiring substrate 111i is a flexible wiring substrate such as a chip on film (COF), a flexible printed circuit (FPC), or a flexible flat cable (FFC).

The communication device 330 may be integrated with the processing circuit 350.
Here, the communication device 330 receives the output information D1 and transmits the input information D2 by communicating with the first processing device 200. That is, the communication device 330 functions as a second coupling portion 331 that is communicably coupled to the first coupling portion 231. In addition, the communication device 330 transmits the output information D1 and receives the correspondence information D4 by communicating with the third processing device 400, when necessary.
The storage circuit 340 is a device that stores various programs executed by the processing circuit 350 and various data processed by the processing circuit 350, and is configured in the same manner as the storage circuit 240 described above. The storage circuit 340 stores the program PG2, the output information D1, the input information D2, and the correspondence information D4.
The program PG2 is a program that enables a computer to realize various functions necessary for generating the input information D2 based on the output information D1. The correspondence information D4 is information regarding the correspondence relationship between the output information D1 and the scanning condition of the print processing to be executed. The details of the correspondence information D4 will be described later with reference to
The processing circuit 350 is a device having a function of controlling each part of the server 300 and a function of processing various data, and is configured in the same manner as the processing circuit 250 described above. The processing circuit 350 functions as a second output portion 351, a second input portion 352, and a calculation portion 353 by reading the program PG2 from the storage circuit 340 and executing the program PG2.
The second output portion 351 outputs the input information D2 via the second coupling portion 331. For example, the second output portion 351 outputs the input information D2 to the first processing device 200 via the second coupling portion 331 using an instruction or the like by the user using the input device 220 as a trigger.
The output information D1 is input to the second input portion 352 via the second coupling portion 331. For example, the output information D1 is input from the first processing device 200 to the second input portion 352 via the second coupling portion 331 using an instruction or the like by the user using the input device 220 as a trigger.
The calculation portion 353 performs a calculation to generate the input information D2 based on the output information D1 and the correspondence information D4. Here, the calculation portion 353 receives input of new correspondence information D4 from the third processing device 400 depending on the collation result of the output information D1 and the correspondence information D4, and generates the input information D2 by using the new correspondence information D4 from the third processing device 400.
More specifically, when information corresponding to the output information D1 from the second input portion 352 is included in the correspondence information D4, the calculation portion 353 generates the input information D2 based on the output information D1 and the correspondence information D4. On the other hand, when information corresponding to the second output information D1b, which has a greater influence on the image quality than the third output information D1c, is included in the correspondence information D4, even when information corresponding to a part of the output information D1 from the second input portion 352 is not included in the correspondence information D4, the calculation portion 353 generates information regarding the scanning condition corresponding to the information closest to the output information D1 from the second input portion 352 among the output information D1 indicated by the correspondence information D4 as the input information D2. In addition, when one or both of the first output information D1a and the second output information D1b from the second input portion 352 are not included in the correspondence information D4, the calculation portion 353 receives the input of the new correspondence information D4 from the third processing device 400, and generates the input information D2 using the new correspondence information D4 from the third processing device 400. The correspondence information D4 stored in the storage circuit 340 is rewritten into the new correspondence information D4.
Here, the third processing device 400 uses the output information D1 from the server 300 to generate new correspondence information D4. That is, the third processing device 400 includes an update portion 410 that updates the correspondence information D4. The update portion 410 updates the correspondence information D4 by appropriately using the information input from the operator of the third processing device 400 or the administrator of the ink jet system 10 in addition to the output information D1 and the correspondence information D4. In addition, the update portion 410 causes the server 300 to transmit the updated correspondence information D4. When the third processing device 400 does not have the original correspondence information D4, the third processing device 400 may update the correspondence information D4 after receiving the input of the correspondence information D4 in addition to the output information D1 from the server 300.
Specifically, in step S101, for example, the acquisition portion 251 acquires the output information D1 by receiving the output information D1 via the input device 220. In step S101, the acquisition order of the first output information D1a, the second output information D1b, and the third output information D1c is not particularly limited and is optional. In addition, for example, the acquisition portion 251 may display an image for a graphical user interface (GUI) for inputting information necessary for acquiring the output information D1 on the display device 210 and appropriately receive information necessary for acquiring the output information D1 from the user using the image.
In step S102, the first processing device 200 outputs the output information D1 to the server 300.
Specifically, in step S102, the first output portion 252 outputs the output information D1 via the first coupling portion 231 with the acquisition of the output information D1 as a trigger. The timing at which the output information D1 is output to the first coupling portion 231 is not limited to the time when the output information D1 is acquired. For example, when the input using the GUI image described above is received, the first output portion 252 may transmit the authentication information such as the user's account information and password to the server 300, when the server 300 succeeds in the authentication using the authentication information, may send the output permission information from the server 300 to the first processing device 200, and when the first processing device 200 receives the output permission information, may output the output information D1 to the server 300.
Next, in step S103, the server 300 inputs the output information D1. In step S104, the server 300 generates the input information D2 based on the output information D1. More specifically, in step S104, the calculation portion 353 performs a calculation to generate the input information D2 based on the output information D1 and the correspondence information D4. The server 300 may inquire about the output information D1 with the predetermined inquiry information, and may cancel the processing after step S104 according to the inquiry result. In addition, the input information D2 indicating that information on the scanning condition of the print processing is not provided may be output to the second output portion 351 according to the inquiry result.
Thereafter, in step S105, the server 300 outputs the input information D2 to the first processing device 200.
Next, in step S106, the first processing device 200 inputs the input information D2. Specifically, in step S106, the input information D2 from the server 300 is input to the first input portion 253 via the first coupling portion 231. The first input portion 253 notifies the user whether or not to input the input information D2 from the server 300 by using the display device 210 or the like, and the input information D2 from the server 300 may be input only when the user inputs an instruction for permitting input by the input device 220 or the like.
In step S107, it is determined whether or not the first processing device 200 executes the print processing under the scanning condition indicated by the input information D2. Specifically, the display device 210 displays an image for receiving an instruction as to whether or not the reception portion 255 executes the print processing under the scanning condition indicated by the input information D2. The reception portion 255 receives the instruction as to whether or not to execute the print processing under the scanning condition indicated by the input information D2 via the input device 220.
When an instruction to execute the print processing under the scanning condition indicated by the input information D2 is received, the first processing device 200 determines the scanning condition of the print processing based on the input information D2 in step S108.
On the other hand, when an instruction not to execute the print processing under the scanning condition indicated by the input information D2 is received, in step S109, the first processing device 200 determines to execute the print processing under another scanning condition input by the user.
The determination portion 254 may determine the scanning condition to be actually used after fine-tuning the scanning condition indicated by the input information D2 by user input using the input device 220.
When the scanning condition is determined by the determination portion 254, the scanning condition is set. Specifically, the number of times of scanning indicated by the first input information D2a and the scanning direction indicated by the second input information D2b are set.
In the calculation of the calculation portion 353, one or both of the first input information D2a and the second input information D2b are adjusted based on the correspondence information D4 so that the scanning condition for the print processing is optimized. Here, in the calculation, it is preferable that one of the first input information D2a and the second input information D2b is adjusted from the viewpoint of ease of adjustment. From the viewpoint of preferably improving the image quality, it is more preferable that the first input information D2a is adjusted.
The image quality obtained differs depending on the head, ink, and medium. When the image quality is poor, the poor image quality can be compensated for by changing the scanning condition such as increasing the number of times of scanning or using the same scanning direction. Depending on the printer manufacturer or printer user, the scanning condition that the head manufacturer did not anticipate may be set, there is a possibility that image quality compensation may not be sufficiently performed. For example, a case where a head manufacturer provides the scanning condition designed to appropriately compensate for image quality in the combination of the premises on the premise of a combination of a certain head, ink, and medium is considered as an example. For the sake of simplicity, the following description describes the case where the printer manufacturer and the printer user match, and the user who purchased the head manufactures the printer by himself or herself and further uses the printer, but it is basically the same even when the printer manufacturer and the printer user are different.
In particular, when the head manufacturer and the printer manufacturer are different, that is, the ink and medium recommended for use are determined by the printer manufacturer. At that time, a printer manufacturer who does not have much knowledge may not be able to determine what type of information on the scanning condition is optimal. It suffices when the head manufacturer can provide the information on the scanning condition in advance, but as described above, the ink and medium recommended for use differ depending on the printer manufacturer, and the information on the optimum scanning condition differs depending on the ink and medium. Therefore, in the past, even the head manufacturer could not determine what type of scanning condition is required to be performed.
For example, depending on the surface tension and viscosity of the ink, the critical surface tension and permeability of the medium, and the like, when a large amount of ink is applied to the medium per unit time, the inks before being fixed may come into contact with each other on the medium and wet to spread, causing blurring of image outlines, blurring of fine lines, and the like. By increasing the number of times of scanning per unit region, the amount of ink discharged per scan, that is, per unit time, is reduced, so that the above problem can be solved. In addition, when the head is scanned in the same direction, the direction where the head is scanned in the opposite direction is interposed between the scans without discharging the ink, so that the amount of ink discharged per unit time is reduced, and the above problem can be solved. However, when the number of times of scanning is unnecessarily increased or the scanning direction is set to the same direction, the recording time is extended. Therefore, it is preferable to vary the scanning condition according to the ink and medium. At this time, it is assumed that the printer manufacturer uses ink and medium different from those assumed by the head manufacturer. In this manner, even when the head manufacturer sets the scanning condition that compensates for the deterioration in image quality with the ink and medium that are assumed in advance and does not extend the extension of the recording time as much as possible, since the ink and medium are different than expected, there is a possibility that adverse effects may occur in image quality and recording time.
In addition, as still another example, the printer manufacturer may have a plurality of types of heads manufactured by the head manufacturer and having different discharge characteristics (different discharge amounts) from each other. When the amount of ink discharged increases, the amount of ink discharged per unit time that is applied onto the medium naturally also increases. Therefore, as in the case of ink and medium, when the printer manufacturer uses a different head than the head assumed by the head manufacturer, there is a possibility that the image quality and recording time may be adversely affected.
As described above, the information on the optimum scanning condition differs depending on the combination of the head, ink, and medium adopted by the printer manufacturer. It may be difficult for printer manufacturers to find the optimum information. On the other hand, even when the head manufacturer tries to provide information on the scanning condition according to the head, ink, and medium in advance, since the information on the scanning condition can be optionally determined by the printer manufacturer, it is difficult to recognize the information on the scanning condition at the time of manufacturing and selling the head. Therefore, it was difficult for the head manufacturer to provide appropriate information on the scanning condition.
In view of this point, in the present embodiment, as described above, the first processing device 200_1 in the hand of the printer manufacturer and the server 300 provided, maintained, and managed by the head manufacturer can be coupled via the communication network NW, and the head, ink, and medium used by the printer manufacturer can be directly input to the server 300 of the head manufacturer. As a result, the appropriate information on the scanning condition according to the head, ink, and medium can be easily provided from the head manufacturer to the printer manufacturer, and the burden on the printer manufacturer can be reduced.
Specifically, in the present embodiment, the first processing device 200 outputs the first output information D1a regarding the head unit 110, the second output information D1b regarding the ink, and the third output information D1c regarding the medium toward the server 300. The server 300 uses the correspondence information D4 to calculate the input information D2 corresponding to the input first output information D1a, the second output information D1b, and the third output information D1c (including the first input information D2a, the second input information D2b, the third input information D2c, and the fourth input information D2d) and outputs the result to the first processing device 200.

Hereinafter, examples of combinations of the number of times of scanning and scanning directions of the head unit 110 will be described with reference to
Thereafter, after the medium M is transported by a predetermined amount, as indicated by Pass3 in
By increasing the number of times of scanning for the unit region RP1 in this manner, the amount of ink discharged per unit time to the unit region RP1 can be reduced, and the number of nozzles N used in the unit region RP1 can be increased, so that image quality can be compensated. However, the width in the Y1 direction of each unit region illustrated in
Thereafter, after the medium M is transported by a predetermined amount, printing is performed for the unit region RP2 in the same manner as the unit region RP1.
By increasing the number of times of scanning for each of the unit region RP1 and the unit region RP2 in this manner, the image quality can be improved compared with the case illustrated in
Next, after transporting the medium M by a predetermined amount and returning the position of the head unit 110 to the original position where Pass1 was started, as indicated by Pass2 in
By setting the scanning directions for the unit region RP1 and the unit region RP2 to be the same in this manner, the amount of ink discharged per unit time for the unit regions RP1 and RP2 can be reduced, and the order of ink discharge can be the same between the unit region RP1 and the unit region RP2, so that image quality can be compensated. However, as described above, since a period is required to move the head unit 110 without discharging ink, the throughput is lower in the case illustrated in
Thereafter, after the medium M is transported by a predetermined amount and the position of the head unit 110 is returned to the original position where Pass1 was started, printing is performed for the unit region RP2 in the same manner as the unit region RP1.
By setting the scanning direction for the unit region RP1 to be the same for Pass1 and Pass2 in this manner, the image quality can be improved as compared with the case illustrated in
As described above, the ink jet system 10 includes the head unit 110, the acquisition portion 251, the first coupling portion 231, the first output portion 252, the first input portion 253, and the determination portion 254. The head unit 110 includes the nozzle N for discharging ink, the pressure chamber C communicating with the nozzle N, and the drive element 111f for applying pressure fluctuation to the ink in the pressure chamber C by supplying the drive pulse PD. The acquisition portion 251 acquires the output information D1 including one or both of the first output information D1a regarding the head unit 110 and the second output information D1b regarding the ink used for the head unit 110. The first coupling portion 231 is communicably network-coupled to the server 300. The first output portion 252 outputs the output information D1 toward the server 300 via the first coupling portion 231. The input information D2 is input to the first input portion 253 from the server 300 via the first coupling portion 231. The determination portion 254 determines the number of times of scanning or the scanning direction of the head unit 110 with respect to the unit region RP1 on the medium M based on the input information D2.
In the above ink jet system 10, since the first output portion 252 outputs the output information D1 toward the server 300 via the first coupling portion 231, the output information D1 can be provided to the head manufacturer. Therefore, by utilizing the knowledge of the head manufacturer in addition to the output information D1, the input information D2 can be efficiently obtained as the information necessary for determining the scanning condition of the print processing. Since the determination portion 254 determines the scanning condition of the print processing based on the input information D2 input from the server 300 to the first input portion 253 via the first coupling portion 231, the scanning condition of the print processing can be determined while reducing the burden on the printer manufacturer.
In the present embodiment, the output information D1 includes the first output information D1a that is information regarding the discharge characteristic of the head unit 110, the second output information D1b that is information regarding the color development property of ink, and the third output information D1c that is information regarding the color development property of the medium M. The output information D1 may include one or both of the first output information D1a and the second output information D1b, and may not include the third output information D1c.
As described above, the determination portion 254 determines the number of times of scanning based on the input information D2. Therefore, the number of times of scanning can be optimized as a scanning condition for print processing.
Here, as described above, when the number of times of scanning in a case in which the discharge characteristic indicated by the first output information D1a is the first discharge characteristic “low discharge performance” is set as the first number of times, the number of times of scanning when the discharge characteristic indicated by the first output information D1a is the second discharge characteristic “high discharge performance” higher than the first discharge characteristic is the second number of times smaller than the first number of times. Therefore, it is possible to reduce the difference in image quality in these cases where the discharge characteristics are different from each other.
In addition, as described above, when the number of times of scanning in a case in which the color development property indicated by the second output information D1b is the first color development property “low color development” is set as the third number of times, the number of times of scanning when the color development property indicated by the second output information D1b is the second color development property “high color development” higher than the first color development property is the fourth number of times smaller than the third number of times. Therefore, it is possible to reduce the difference in image quality in these cases where the color development properties of the inks are different from each other.
Furthermore, when the number of times of scanning in a case in which the color development property indicated by the third output information D1c is the third color development property “low color development” is set as the fifth number of times, the number of times of scanning when the color development property indicated by the third output information D1c is the fourth color development property “high color development” higher than the third color development property is the sixth number of times smaller than the fifth number of times. Therefore, it is possible to reduce the difference in image quality in these cases where the color development properties of the mediums are different from each other.
In the present embodiment, as described above, the determination portion 254 determines the scanning direction based on the input information D2. Therefore, the scanning direction can be optimized as a scanning condition for print processing.
Here, as described above, when the scanning direction in a case in which the discharge characteristic indicated by the first output information D1a is the first discharge characteristic “low discharge performance” is unidirectional, in a case in which the discharge characteristic indicated by the first output information D1a is the second discharge characteristic “high discharge performance” higher than the first discharge characteristic, the scanning directions may be bidirectional. Therefore, it is possible to reduce the difference in image quality in these cases where the discharge characteristics are different from each other.
In addition, as described above, when the scanning direction in a case in which the color development property indicated by the second output information D1b is the first color development property is unidirectional, in a case in which the color development property indicated by the second output information D1b is the second color development property higher than the first color development property, the scanning directions may be bidirectional. Therefore, it is possible to reduce the difference in image quality in these cases where the color development properties of the inks are different from each other.
Furthermore, as described above, when the scanning direction in a case in which the color development property indicated by the third output information D1c is the third color development property is unidirectional, in a case in which the color development property indicated by the third output information D1c is the fourth color development property higher than the third color development property, the scanning directions may be bidirectional. Therefore, it is possible to reduce the difference in image quality in these cases where the color development properties of the mediums are different from each other.
As described above, the ink jet system 10 further includes a reception portion 255 that receives an instruction by the user as to whether or not to execute the print processing in the number of times of scanning or in the scanning direction indicated by input information D2. When the reception portion 255 receives an instruction to execute the print processing in the number of times of scanning or in the scanning direction indicated by the input information D2, the determination portion 254 determines to execute the print processing in the number of times of scanning or in the scanning direction indicated by the input information D2. On the other hand, when the reception portion 255 receives an instruction not to execute the print processing in the number of times of scanning or in the scanning direction indicated by the input information D2, the determination portion 254 determines to execute print processing in another number of times of scanning or in another scanning direction input by the user. As described above, by making the determination of the determination portion 254 based on the instruction received by the reception portion 255, the convenience of the printer manufacturer can be enhanced.
In addition, as described above, the ink jet system 10 includes the ink discharge device 100, the first processing device 200, and the server 300. The ink discharge device 100 is provided with the head unit 110. The first processing device 200 is coupled to the ink discharge device 100 and includes the display device 210 which is an example of a “display portion” that displays information regarding the ink discharge device 100. Therefore, printing based on the recorded data DP from the first processing device 200 can be performed by the ink discharge device 100. In addition, various information can be communicated between the ink discharge device 100 and the first processing device 200. Furthermore, various information necessary for the user of the ink discharge device 100 can be notified via the display device 210.
Here, as described above, the server 300 includes the storage circuit 340, which is an example of a “storage portion”, and the calculation portion 353. The storage circuit 340 stores in advance the correspondence information D4 regarding the correspondence relationship between the output information D1 and the number of times of scanning or the scanning direction of the print processing to be executed. The calculation portion 353 performs a calculation to generate the input information D2 based on the output information D1 and the correspondence information D4. In such a configuration in which the input information D2 is generated using the correspondence information D4, the input information D2 can be rapidly generated.
