1. Field of the Invention
The present invention relates to a color print control method and apparatus and, more particularly, to a color matching setting method when outputting data to a plurality of color printers via a network.
2. Description of the Related Art
These days, POD (Print On Demand) has been proposed and is widely prevailing as one business printing field. The POD implements printing of various materials in small volumes. In the POD, electronic data is generally input as a document, and, for example, an electrophotographic printer prints out without making the plate of the data.
Along with the development of electrophotographic printers toward color printing, color printers have been introduced into the POD. Similar to conventional printing, color management is one of important subjects. In the POD, color management generally adopts color matching using an ICC profile. When stricter color matching is required, a plurality of profiles must be prepared as the ICC profile (printer profile) of a printer and selectively used in accordance with printout paper.
Recently in the POD, a clustering configuration also appears, in which a plurality of printers are connected to print out the same data. For example, according to a technique disclosed in Japanese Patent Laid-Open No. 2002-084433, a printer profile is selected in correspondence with paper.
However, printouts in the clustering configuration slightly differ between individual color printers of the cluster even if the color printers are of the same model. For this reason, it is necessary to provide a profile corresponding to printout paper for each printer. The following operation is necessary in a rendering unit which renders input print data or a control unit for the rendering unit in a printer control which controls clustering printing. In executing clustering printing, the rendering unit or control unit identifies a destination color printer, and acquires, from a printer profile management unit, a printer profile optimum for each printer and output-designated paper.
However, according to the technique disclosed in Japanese Patent Laid-Open No. 2002-084433, a printer profile is selected in correspondence with paper, but the relationship between a profile and a printer which forms a cluster is not managed. Hence, the rendering unit or control unit must acquire a profile for each printer, and repeats profile acquisition, resulting in a cumbersome process.
The present invention has been made to overcome the conventional drawbacks, and has as its object to provide a color print control method and apparatus for acquiring an optimum profile by a simple profile acquisition process in consideration of the clustering configuration.
To solve the above-described problems, a color print control apparatus according to the present invention comprising:

Moreover, one client may incorporate the arrangements of clients A, B, and C.
<Description of Structure Example of Data Used in Embodiment>
Data mainly used in the embodiment will be described with reference to
(Structure Example of Color Setting Information)
As described above, the color setting information describes a color matching process in addition to a rendering intent and a profile applied to perform a color matching process for job data. The color management processor 16 in the front-end server 1 executes a color matching process complying with the description contents.
As shown in
The color setting information is made up of the following five categories. First, the color setting information has a printer profile field 502 which describes a printer profile name used in the color matching process. The color setting information has a text object setting category 503 which describes a target profile used in a color matching process for a text object, a rendering intent in color matching, other special process settings, and the like. The text object setting category 503 categorizes settings applied to a color matching process for a text object described in PDL of job data. The color setting information has an image object setting category 504 which categorizes settings applied to a color matching process for an image object described in PDL of job data, similar to the text object setting category 503. The color setting information has a graphic object setting category 505 which categorizes settings applied to a color matching process for a graphic object described in PDL of job data. The color setting information has a color setting name field 501 which manages, as one record, settings in the printer profile field 502 to the graphic object setting category 505.
A set of data in these five categories is managed as one record. In the embodiment, a plurality of records are stored in the color setting storage 17A and managed by the color setting manager 17.
The text object setting category 503 among the five categories includes an RGB target profile field 503A which describes a profile name applied when a text object is RGB data. The text object setting category 503 includes an RGB rendering intent field 503B which designates a color matching method when the RGB target profile field 503A is applied. The text object setting category 503 includes a CMYK target profile field 503C which describes the profile name of a simulation target when a text object is CMYK data or CMYK simulation is to be performed. The text object setting category 503 includes a CMYK rendering intent field 503D which designates a color matching method when the CMYK target profile field 503C is applied. The text object setting category 503 includes a spot color application color setting field 503E which describes a spot color set name (to be described later). The text object setting category 503 includes a CMYK simulation setting field 503F which sets whether or not to apply CMYK simulation. The text object setting category 503 includes a black guarantee setting field 503G which sets whether or not to apply black guarantee.
The image object setting category 504 and graphic object setting category 505 also have the same data items 52 as those of the text object setting category 503, a detailed description of which will not be repeated.
(Profile Management Form Example)
The RGB target 61 and CMYK target 62 manage pairs of color profile entities and profile names. Color setting information in the embodiment describes a profile name, and the color setting manager 17 specifies a paired color profile entity.
The printer profile 63 manages pairs of color profile entities and profile names for each printer engine 2. The profile name is a paper name. Although a detailed description of the color profile entity will be omitted, the following three data are managed on the assumption of correction by calibration. The three data are an initial profile immediately after creating a profile, a profile immediately before executing correction, and a current profile actually used for the color matching process.
The printer profile 63 manages pairs of paper names and profile entities as a reference profile serving as a color matching reference in clustering, in addition to profiles corresponding to the printer engines 2-1, 2-2, and 2-3.
Unlike color profiles, the entity of the spot color conversion set 64 is a set of data each made up of a pair of a color name (e.g., specific ink name) described in PDL, and C, M, Y, and K values in printer output. One unit data will be called spot color data, and one set will be called a spot color set. The spot color set is given a name (to be referred to as a spot color set name hereinafter). Color setting information in the embodiment describes the spot color set name, and the color setting manager 17 specifies a paired spot color set.
The color management processor 16 in the front-end server 1 executes color matching in the embodiment using an RGB target or CMYK target as an input profile and the above-mentioned reference profile as an output profile. The color management processor 23 in the printer engine 2 executes color matching using the reference profile as an input profile and a printer profile managed for each printer engine 2 as an output profile. The front-end server 1 applies a spot color when a job data file describes a color name instead of a color matching process using input and output profiles. The color matching process is achieved by a known technique.
(Structure Example of Virtual Printer Management Data)
A virtual printer in the embodiment means a combination of printer engines 2 when the printer engines 2 connected to the front-end server 1 are arbitrarily combined and clustered. By combining the printer engines 2, a plurality of printers can be treated virtually as one printer. Virtual printer management data 71 associates a virtual printer with the clustered printer engines 2. In the embodiment, virtual printer A corresponds to the printer engines 2-1, 2-2, and 2-3. Virtual printer B corresponds to the printer engines 2-1 and 2-3 and a printer engine 2-4 (not shown in
(Structure Example of Job Ticket)
Job data 80 is made up of job ticket data 81 which describes contents designating a process, and a job data file serving as actual output data such as PDF, PS, TIFF, or JPEG.
The job ticket data 81 contains, as layout information, paper size setting information, paper type information, and page orientation information. The job ticket data 81 contains color setting information 82 as information on color management.
The color setting information 82 is a description of color setting information in the job ticket data 81. The color setting information 82 contains a color setting name 821, printer profile 822, text object setting category 823, image object setting category 824, and graphic object setting 825.
The color setting information 82 can describe the same contents as color setting information described with reference to
The color setting manager 17 can recognize details of the setting contents of the color setting information 82. Thus, for color settings managed by the color setting manager 17, the color setting information 82 may also describe only the color setting name 821.
For color settings not managed by the color setting manager 17, the color setting information 82 describes the printer profile 822, text object setting category 823, image object setting category 824, and graphic object setting 825. The color setting name 821 describes a specific name representing that the color setting manager 17 does not manage these settings. In the embodiment, a character string “separate settings” is used as the color setting name.
<Operation Examples of Registration, Editing, and Deletion of Color Setting Information>
Registration, deletion, and editing of color setting information stored in the color setting storage 17A will be explained with reference to
According to the embodiment, based on an operation by the operator for color setting information, color settings are newly registered in the color setting storage 17A, or registered color settings are edited or deleted. At this time, the color setting editing unit 30 in client A communicates with the color setting manager 17 in the front-end server 1 via the network I/Fs 10A and 10B.
(Window Display Examples by Color Setting Editing Unit 30)
Window display examples by the color setting editing unit 30 in client A will be explained with reference to

By pressing the profile rollback button 114, a window further appears. The operator designates either the immediately preceding profile or initial profile via this window, and designates the start of rollback, rolling back the profile.
<Example of Color Setting Information Maintenance Process by Color Setting Editing Unit 30>
The sequence of a color setting information maintenance process by the color setting editing unit 30 of client A will be described with reference to
Upon activation, in step S1201, the color setting editing unit 30 requests the color setting manager 17 of the front-end server 1 via the network I/F 10A to acquire information managed by the color setting manager 17. Information to be acquired includes a color setting list of color setting names described in the color setting name field 501 for color settings, and values settable in the data items 52 of color settings. The color setting editing unit 30 acquires the color setting list and settable values transmitted from the color setting manager 17 in response to the acquisition request, and stores them in the temporary color setting information storage 30A.
In step S1202, the color setting editing unit 30 sets the color setting list acquired in step S1201 in the color setting list display column 93, and displays the color setting window 91. After displaying the color setting window 91, the color setting editing unit 30 waits in step S1203 for a work selection instruction from the operator. The process branches in accordance with work selected by the operator.
If the operator selects registration with the registration button 94 in step S1203, the process advances to step S1204. In step S1204, the color setting editing window described with reference to
If the operator selects deletion with the delete button 96 in step S1203, the process advances to step S1205. In step S1205, the color setting editing unit 30 deletes color setting information alternatively selected by the operator from the color setting list display column 93. In the embodiment, information representing the deletion instruction is associated with a color setting name stored in the temporary color setting information storage 30A. Upon completion of deletion, the process advances to step S1208.
If the operator selects editing with the edit button 95 in step S1203, the process advances to step S1206. In step S1206, the color setting editing unit 30 requests the color setting manager 17 to acquire the data item 52 corresponding to color setting information alternatively selected by the operator from the color setting list display column 93. The color setting editing unit 30 receives the requested data item 52. In step S1207, the color setting editing unit 30 displays the color setting editing windows 101 and 102 described with reference to
In step S1208, the color setting editing unit 30 refers to color setting names stored in the temporary color setting information storage 30A, and creates again a color setting list reflecting newly registered and deleted color settings. After that, the process returns to step S1202 to set the re-created color setting list in the color setting list display column 93 and display the color setting window 91.
The process in steps S1202 to S1208 is repetitively executed until the operator completes desired color setting information maintenance.
When the process returns to step S1203, and the operator completes desired editing and selects the end of the process with the OK button 97, the process advances to step S1209. In step S1209, the color setting editing unit 30 requests the color setting manager 17 to reflect the maintenance results. Upon receiving the process completion notification in response to the request, the process ends.
In
(Acquisition of Initial Information: Sequence Example in S1201)
Details of the process in the above-described step S1201 to acquire a color setting list and settable values from the color setting manager 17 by the color setting editing unit 30 will be described with reference to
In step S1301, the color setting editing unit 30 in client A issues a color setting list acquisition request. The acquisition request reaches the color setting manager 17 via the network I/F 10A and the network I/F 10 of the front-end server 1 connected to the network 3. In step S1302, upon receiving the acquisition request, the color setting manager 17 in the front-end server 1 collects color setting names from the color setting name field 501 in accordance with color settings stored in the color setting storage 17A. The color setting manager 17 creates a color setting list, and transmits it to the color setting editing unit 30.
Upon receiving the color setting list from the color setting manager 17, the color setting editing unit 30 issues a settable value acquisition request to the color setting manager 17 in step S1303 in order to acquire values settable in the data items 52 of color setting information. In step S1304, upon receiving the acquisition request, the color setting manager 17 acquires the settable values stored in the color setting storage 17A, and transmits them to the color setting editing unit 30.
Upon receiving the transmitted settable values, the color setting editing unit 30 stores, in the temporary color setting information storage 30A, the color setting list received in step S1302 and the settable values received in step S1304.
(Acquisition of Color Setting Details: Sequence Example in S1206)
Details of the process in step S1206 to acquire, from the color setting manager 17 by the color setting editing unit 30, the setting values of the data items 52 of color setting information to be edited will be described with reference to
In step S1401, the color setting editing unit 30 in client A issues a request to acquire the setting values of the data items 52 together with a data setting name to be edited, as detailed information of color setting information alternatively selected as an editing target by the operator. The acquisition request reaches the color setting manager 17 via the network I/F 10A and the network I/F 10 of the front-end server 1 connected to the network 3. In step S1402, upon receiving the acquisition request, the color setting manager 17 in the front-end server 1 acquires the data items 52 of the color setting information stored in the color setting storage 17A, and transmits them to the color setting editing unit 30. The data items 52 are those of color setting information having a color setting name which coincides with the color setting name transmitted from the color setting editing unit 30 and is described in the color setting name field 501 stored in the color setting storage 17A. The color setting editing unit 30 receives the transmitted data items 52, and stores them in the temporary color setting information storage 30A.
(Reflection in Color Setting Manager: Sequence Example in S1209)
Details of the process in step S1209 to request the color setting manager 17 to reflect a maintenance result, and receive a process completion notification will be described with reference to
In step S1501, the color setting editing unit 30 in client A issues a setting change request in order to reflect, in the color setting manager 17, the result of deleting, newly registering, or editing color setting information temporarily stored in the temporary color setting information storage 30A. The color setting editing unit 30 transmits a color setting name as for deleted color setting information, and transmits data items in addition to a color setting name as for newly registered or edited color setting information. The setting change request reaches the color setting manager 17 via the network I/F 10A and the network I/F 10 of the front-end server 1 connected to the network 3.
In step S1502, upon receiving the setting change request, the color setting manager 17 in the front-end server 1 stores newly registered color setting information as new color setting information in the color setting storage 17A. As for edited color setting information, the color setting manager 17 searches the color setting storage 17A for color setting information to be changed, and rewrites the change portion. As for deleted color setting information, the color setting manager 17 searches the color setting storage 17A for the color setting name field 501 subjected to deletion, and deletes color setting information corresponding to the color setting name field 501.
Upon completion of new registration, editing, or deletion requested by the color setting editing unit 30, the color setting manager 17 transmits a completion notification to the color setting editing unit 30 in client A. The color setting editing unit 30 receives the completion notification, and the process ends.
Registration, deletion, and editing of color setting information have been described with reference to
<Color Setting Operation Examples by Hot Folder Manager>
An operation to acquire, by a host folder or printer driver, color setting information managed by the color setting manager 17, and output a job to which color matching based on the acquired color setting information is applied will be explained.
Association of color setting information with a hot folder will be explained.
In the embodiment, job data is prepared by assigning a job ticket containing color setting information to a job data file input to the hot folder manager 11C in the front-end server 1. For this purpose, proper color setting information must be selected from pieces of color setting information managed by the color setting manager 17, and stored in the color setting information manager 11F to manage the selected color setting information and hot folder in association with each other. In the embodiment, the same color setting can be associated with a plurality of hot folders. One hot folder is associated with one color setting.
(Example of Hot Folder Setting Window)
In
A color setting selection column 163 displays the color setting name of a hot folder alternatively selected in the hot folder selection column 161. The initial display is a color setting information name associated with the alternatively selected hot folder. At this time, when color setting information associated with the alternatively selected hot folder has been edited and is not managed by the color setting manager 17, the color setting name is “separate settings”.
A color setting content check button 164 is used to display a setting content check window for color setting information selected in the color setting selection column 163. A color setting adjustment button 165 is used to display an adjustment window for adjusting the setting contents of color setting information selected in the color setting selection column 163. The adjustment window has a window display as shown
A virtual printer selection column 166 is used to acquire a virtual printer list managed by the printer manager 15 and alternatively select a destination virtual printer based on the acquisition result.
(Sequence Example of Associating Hot Folder with Color Setting)
A process sequence to store a color setting in the color setting information manager 11F in association with a hot folder managed by the hot folder manager 11C will be described with reference to the flowchart of
In step S1701 of
In this step, the process is complete within the front-end server 1, and no communication is done via the network I/F.
After acquiring the initial information, a color setting name described in the color setting list is set in the color setting selection column 163. If the color setting information manager 11F holds edited color setting information, the hot folder setting window 160 is displayed together with “separate settings”.
In step S1702, the process waits for a work selection instruction from the operator, and branches in accordance with work selected by the operator.
In step S1702, if the operator operates the hot folder management button group 162 in the hot folder setting window 160 or requests other settings including a paper setting (not shown), the process advances to step S1703. In step S1703, settings other than color setting information are made, and the process returns to step S1702. If the operator selects a destination virtual printer from the virtual printer selection column 166 in step S1703, the setting information manager 11E stores the selected virtual printer.
After the process returns to step S1702, if the operator changes selection of the color setting name in the color setting selection column 163 while alternatively selecting a hot folder from the hot folder selection column 161, the process advances to step S1704. In step S1704, the color setting name which is stored in the color setting information manager 11F and associated with the hot folder alternatively selected in step S1702 is replaced with the color setting name changed in the color setting selection column 163. If the color setting information has been edited in step S1706, that is, the color setting name is “separate settings”, the data items of the color setting information stored in the color setting information manager 11F are also deleted. If, for example, a hot folder is newly created in step S1703 and is not associated with any color setting, color setting information can be associated with the hot folder by executing step S1704. After the end of the process in step S1704, the process returns to step S1702.
After the process returns to step S1702, if the operator designates check or editing of color settings with the color setting content check button 164 or color setting adjustment button 165 while alternatively selecting a hot folder from the hot folder selection column 161, the process advances to step S1705. In step S1705, a color setting name stored in the hot folder manager 11C and color setting information manager 11F in correspondence with the alternatively selected hot folder is acquired. The color setting manager 17 is requested to acquire the data items of color setting information corresponding to the color setting name. The data items are then received as a result of the request. In step S1705, the color setting manager 17 is requested to acquire detailed color setting information from the hot folder manager 11C. The data items are then received as a result of the request. If the color setting name associated with the alternatively selected hot folder is “separate settings”, the data items of color setting information are read out from the color setting information manager 11F.
In step S1706, a window identical to the color setting name editing windows 101 and 102 described with reference to
In step S1702, if the operator designates the end of setting a hot folder, the process ends. Consequently, association of a hot folder managed by the hot folder manager 11C with color setting information is complete.
<Example of Inputting Job Data to Hot Folder by Print Data Creation/editing Unit 42>
A sequence example after the print data creation/editing unit 42 in client C inputs a job data file to a hot folder managed by the hot folder manager 11C in the front-end server 1 will be described with reference to
In step S1801, the hot folder manager 11C acquires information associated with the job data file-input hot folder from the setting information manager 11E and color setting information manager 11F. Subsequently, the hot folder manager 11C requests the job ticket generation/editing unit 11D to generate a job ticket based on the acquired information, and receives the job ticket as a result of the request.
In step S1802, the hot folder manager 11C composites the received job data file with the job ticket generated in step S1801 into job data as shown in
In step S1803, the hot folder manager 11C delivers the job data to the job manager 11A. The job manager 11A manages the job in preparation for printing.
The process until a job data file input from client C is delivered to the job manager 11A as job data containing color settings managed by the color setting manager 17 has been described.
<Example of Creating and Inputting Job Data by Printer Driver 40>
A process to create job data containing color setting information by the printer driver 40 in client B and input a job to the front-end server 1 will be explained with reference to

By giving an instruction with an output start button 194, a designated document is converted into PDL, and job ticket data is created with settings necessary for printing, including color settings and settings (not shown). The job ticket data and job data are composited to input the job to the front-end server 1.
(Sequence Example of Creating and Transmitting Job Data)
In step S2001 of
After acquiring the initial information, a color setting name described in the color setting list is set in the color setting selection column 191 and displayed in the print quality setting window 190. Then, the process advances to step S2002. In step S2002, the process waits for a work selection instruction from the operator, and branches in accordance with work selected by the operator.
In step S2002, if the operator has changed the print resolution setting, a setting other than color settings has been made, and the process advances to step S2003. In step S2003, the change of the print resolution is accepted to store the setting value in the setting information manager 40C. Thereafter, the process returns to step S2002.
After the process returns to step S2002, if the operator has changed color settings in the color setting selection column 191, the process advances to step S2004. In step S2004, the color setting information manager 40D stores the color setting name selected in step S2002, and the process returns to step S2002.
After the process returns to step S2002, if the operator designates check or editing of color settings with the color setting adjustment button 192 or color setting check button 193, the process advances to step S2005. In step S2005, the color setting name stored in the color setting information manager 40D in step S2004 is acquired. The color setting manager 17 is requested to acquire the data items of color setting information corresponding to the color setting name. The data items are then received as a result of the request. Step S2004 is the same as acquisition of color setting details described with reference to
In step S2006, a window identical to the color setting name editing windows 101 and 102 described with reference to
In step S2002, if the operator issues an instruction with the output start button 194, the process advances to step S2007 in order to start the output process. In step S2007, the settings of the job are read out from the setting information manager 40C and color setting information manager 40D. The job ticket generator 40A is requested to create a job ticket. Upon receiving the process result, the process advances to step S2008. If the color setting name is “separate settings” in generating a job ticket with color settings, it is described in the job ticket including detailed settings. If the operator has not edited any data item of color setting information corresponding to the color setting name, only the color setting name is described.
In step S2008, the PDL generator 40B is used to generate PDL from a document held by the document creation application 41. In step 32009, the job ticket generated in step S2007 and the PDL generated in step S2008 are composited into job data. In step S2010, the job data is transmitted to the job controller 11 of the front-end server 1 via the network I/F 10C.
Upon receiving the job data, the job manager 11A in the job controller 11 manages the job in preparation for printing.
The process until client B delivers job data containing color settings managed by the color setting manager 17 to the job manager 11A in order to print a document created by the document creation application 41 has been described.
<Operation Examples of Print Process and Change of Color Settings for Job Data>
Change of color settings for job data which is created by the hot folder manager 11C or printer driver 40 and managed by the job manager 11A, and a print process will be described.
(Example of Print Job Management Window)
A job management window displayed by the job controller 11 will be explained with reference to
A job management window 210 has a hot folder display column 211, a printed job display column 212, and a held job display column 213 which displays jobs held in the job manager 11A.
The hot folder display column 211 displays a list of hot folders managed by the hot folder manager 11C. The printed job display column 212 displays a list of job data which are managed by the job manager 11A and have already been printed. The held job display column 213 displays a list of jobs (held jobs) which are managed by the job manager 11A and wait for the start of printing. The held job display column 213 displays, as a held job, a job created by the hot folder manager 11C or printer driver 40.
<Sequence Example of Job Data Print Process>
A held job print process will be explained with reference to the flowchart of
In step S2201, the operator alternatively selects a held job and designates work. In step S2202, the process branches in accordance with the work designation.
If the work designation is change of job settings, the process advances to step S2203; if it is printing, to step S2204. In step S2203, the print condition settings of the alternatively selected job data are changed. The color setting change process in step S2203 will be described with reference to
In step S2204, only job ticket data is extracted from the job data, and the process advances to step S2205. In step S2205, the job analyzer 11B analyzes the job ticket data, and the process advances to step S2206. In step S2206, output paper type information in the job ticket data of
(Change of Job Settings: Color Setting Change Process Sequence in S2203)
When changing the print conditions of a held job, the settings are changed in step S2203 described above. Details of step S2203 will be described with reference to
In changing settings, the job controller 11 displays a window having the same items as those of the print quality setting window 190 described with reference to
In step S2301, only job ticket data is extracted from job data, and the process advances to step S2302. In step S2302, the job analyzer 11B analyzes the job ticket data to store the analysis result. Then, the process advances to step S2303.
Step S2303 is the same as the initial process in step S1201 described with reference to
In step S2304, the process waits for a work selection instruction from the operator, and branches in accordance with work selected by the operator.
In step S2304, if the operator has changed the print resolution setting, the process advances to step S2305. In step S2305, the change of the print resolution is accepted to change the job ticket analysis result in step S2302. Then, the process returns to step S2304.
After the process returns to step S2304, if the operator has changed color settings in the color setting selection column 191, the process advances to step S2306. In step S2306, the color setting name as a result of analyzing the job ticket in step S2302 is changed to the color setting name selected in step S2304. After that, the process returns to step S2304. If the job ticket holds “separate settings”, detailed data items are described in addition to the color setting name, and thus erased.
After the process returns to step S2304, if the operator designates check or editing of color settings with the color setting adjustment button 192 or color setting check button 193, the process advances to step S2307. In step S2307, the color setting name described in the job ticket is acquired. The color setting manager 17 is requested to acquire the data items of color setting information corresponding to the color setting name. The data items are then received as a result of the request. If the color setting name described in the job ticket is “separate settings”, the data items of color setting information are read out from the color setting information manager 11F.
In step S2308, a window identical to the color setting name editing windows 101 and 102 described with reference to
In step S2304, if the operator issues an instruction with the output start button 194, the process advances to step S2309 in order to start the output process. In this process, the output start instruction is the completion of changing settings. In step S2309, the job ticket generation/editing unit 11D is requested to create a job ticket from the job ticket analysis result changed by the above-mentioned process. Upon receiving the process result, the process advances to step S2310. If the color setting name is “separate settings” in generating a job ticket with color settings, it is described in the job ticket including the data items of the color setting information; otherwise, only the color setting name is described. In step S2310, the job ticket in the job data is updated to the job ticket created in step S2309.
(Detailed Sequence Example of Outputting Job Data)
In step S2401, the process of a job file held in the job manager 11A restarts, and the process advances to step S2402.
In step S2402, detailed information of color settings is acquired from the color setting manager 17 in accordance with the job ticket analysis result in step S2205 of
In step S2403, the PDL interpreter 12 analyzes job file data to generate intermediate data, and the process advances to step S2404. In step S2404, the intermediate data storage 13 stores the intermediate data generated in step S2403, and the process advances to step S2405. In step S2405, the color management processor 16 executes a color matching process for the intermediate data stored in the intermediate data storage 13 by using a profile described in the color settings of the job ticket analysis result. The color matching process adopts a normal sequence to perform a color matching process for RGB or CMYK data, and uses an RGB or CMYK target profile and a reference profile. Thereafter, the process advances to step S2406.
In step S2406, the intermediate data stored in the intermediate data storage 13, the profiles, and detailed information of color settings are transmitted to the printer engines 2 which form a destination virtual printer described in the job ticket. The printer engines are obtained from the virtual printer by inquiring them of the printer manager 15. In step S2407, the rendering unit 22 in the printer engine 2 rasterizes the data into bitmap image data, and the process advances to step S2408. In step S2408, the color management processor 23 performs a color matching process for the rasterized bitmap image data in accordance with a profile and detailed information of color settings corresponding to a paper name described in the color settings of the job ticket analysis result in S2402. At this time, color matching is done using a printer profile corresponding to the reference profile and paper name.
In step S2409, paper is selected based on Info_media information, and the process advances to step S2410. In step S2410, data is printed on the selected paper, and the process ends.
By designating a paper name as a color setting, the front-end server analyzes the virtual printer and paper name. As a result of the analysis, each printer engine which forms the virtual printer can perform color matching using a profile corresponding to paper. Thus, it suffices to designate a profile not for each printer engine which forms the virtual printer, but for each virtual printer. Since a profile can be designated by the paper name, color matching can be executed for an image signal representing a printing material (toner or ink) whose limit amount is determined by the paper type.
(Acquisition of Detailed Information of Color Settings: Sequence Example in S2402)
The process in S2402 to acquire detailed information of color settings and a profile from the color setting manager 17 by the job controller 11 based on the contents of a job ticket analyzed in step S2205 will be described.
In step S2501, the job controller 11 notifies the color setting manager 17 of a virtual printer. In step S2502, the job controller 11 determines whether the color setting name is “separate settings”. If the color setting name is “separate settings”, the process advances to step S2509; if the color setting name is not “separate settings”, to step S2503. In step S2503, the job controller 11 notifies the color setting manager 17 of a color setting name. In step S2504, the job controller 11 requests the color setting manager 17 to acquire detailed information of the color settings notified in step S2503. The color setting manager 17 searches for color setting information corresponding to the color setting name, and notifies the job controller 11 of detailed information of the detected color settings. In step S2509, the job controller 11 separately acquires a profile.
In step S2505, the job controller 11 requests the color setting manager 17 to acquire a spot color set, and profiles corresponding to RGB and CMYK target profile names and a spot color set name which are described in the acquired detailed information of color settings. The color setting manager 17 delivers, to the job controller 11, a profile entity associated with the notified profile name or spot color set name.
In step S2506, the job controller 11 requests the color setting manager 17 to acquire a printer profile. In step S2507, the color setting manager 17 acquires, from the printer manager 15, the printer engines 2 which form the virtual printer notified in step S2501. In step S2508, the printer profile 63 is searched for a paper name described in the detailed information of color settings in correspondence with the printer engines 2 obtained in step S2507. The color setting manager 17 acquires a current profile from printer profiles associated with the detected paper name, and delivers it to the job controller 11 in association with the printer engines 2. Each printer engine 2 which forms the virtual printer can execute color matching using the current profile.
According to the embodiment, the printer driver 40 acquires color setting information upon receiving a printing instruction. However, the printer driver 40 can also acquire color setting information at a timing different from the printing instruction.
From the beginning of configuring the system, the hot folder manager 11C and printer driver 40 may hold all or some pieces of color setting information identical to color setting information managed by the color setting manager 17. It is also possible to, at a predetermined timing when, for example, color setting information managed by the color setting manager 17 is updated, acquire or receive the updated color setting information and mirror the management contents in the color setting manager 17.
