Description
BACKGROUND
Field of the Disclosure

The present disclosure relates to an information processing apparatus, a control method of an information processing apparatus, and a storage medium.


Description of the Related Art

In commercial printing services, a printing firm often receives quality terms for a printed product that have been designated by a customer. The quality terms refer to conditions related to quality of the printed product. Examples of the quality terms include an amount of a positional shift between images on front and back sides of a sheet, and an amount of fluctuation in a color value between images on a plurality of copies or a plurality of pages.


Variety of printed products is wide and includes a material to be distributed such as a flyer and a pamphlet, a photo collection, a book, a name card, and an exhibit panel. Since use applications and prices of such printed products range widely, the quality terms include various requirements and standards.


A printing firm creates a printed product while performing various adjustment work to satisfy these quality terms. For example, based on a sample printing result agreed to by a customer, the printing firm performs various adjustments to obtain a specific color on a specific sheet by a printing apparatus, and removes a printed product determined as not satisfying the quality terms as a defective product in an inspection conducted after printing. The printing firm checks whether the quality of the printed product achieved through such work satisfies the quality terms required by the customer, and submits a quality report to the customer as necessary.


In view of the foregoing, as a method of standardizing information formats for transmitting the quality terms and quality reports, print requirements exchange (PRX) and print quality exchange (PQX) respectively discussed in “ISO/AWI 20616-1, Graphic technology File format for quality control and metadata Part 1: Print requirements exchange (PRX) www.iso.org/standard/68565.html” and “ISO/CD 20616-2, Graphic technology File format for quality control and metadata Part 2: Print quality exchange (PQX) www.iso.org/standard/69572.html” are considered as standardization techniques.


The PRX refers to a standard data format of quality terms required of printing. By using the PRX, it becomes possible to describe the quality terms for different customers or different orders in a uniform standard data format.


The PQX refers to a standard data format of a print quality report. The PQX enables quality data of a printed product to be transmitted in a standard data format. By using the PRX and the PQX in this manner, it becomes possible to transmit the quality terms and quality reports that have not been conventionally standardized in a standardized information format.


Japanese Patent Application Laid-Open No. 2016-115362 discusses a technique of generating a quality requirement for each order for a printed product when the order is received. In a system discussed in Japanese Patent Application Laid-Open No. 2016-115362, required quality is estimated based on a history of past printed products of a customer to determine an image quality target value to be obtained.


Although information formats for transmitting quality terms and quality reports have been proposed, how to apply the information formats to an order reception system that determines print quality as discussed in Japanese Patent Application Laid-Open No. 2016-115362 has not been conventionally considered.

DESCRIPTION OF THE EMBODIMENTS

An exemplary embodiment of the present disclosure will be described in detail below with reference to the attached drawings. The following exemplary embodiment is not intended to limit the present disclosure set forth in the appended claims, and not all combinations of features described in the exemplary embodiment are always essential to the solving means of the present disclosure.


As for a quality standard of image quality or image displacement between front and back sides, a printing order reception firm or a printing firm usually has a standard setting. Thus, a customer only performs a predetermined print setting, and accordingly, printing is performed in such a manner as to satisfy the quality standard.


On the other hand, quality terms related to reproducibility and stability of color vary depending on customers or printed products, and there can be numerous methods for satisfying the quality terms.


The color reproducibility is an index indicating whether a color defined by Red, Green, Blue (RGB) or Cyan, Magenta, Yellow, Key plate (CMYK) is printed in the same color in a printed product.


The color stability is an index indicating whether print data of the same color is printed in an invariable color in a printed product in the printing of a plurality of pages or a plurality of copies.


A corporate color is a color representing a company or an organization. Thus, a customer usually demands high color reproducibility and stability therefore. More specifically, a customer generally demands, as quality terms, that the corporate color be printed in the same color as a color provided in print data and that a printing result thereof does not vary between pages. In addition, the printing result is often input to the customer as a numerical value indicating a color difference.


A conventional order reception system is unable to receive such a detailed setting related to print quality. The conventional order reception system only holds quality terms determined for each product type, and does not have a structure for reflecting detailed quality terms of a customer in the held quality terms. Thus, when introducing print requirements exchange (PRX), it is necessary to consider how the order reception system receives the detailed quality terms of a customer and converts the detailed quality terms into a format of the PRX.


In a first exemplary embodiment, there is discussed a printing order reception system that creates quality requirement data for satisfying quality terms required by a customer. The printing order reception system calculates necessary quality requirement parameters by analyzing print settings and quality terms set by the customer, so that the quality requirement parameters can be input to a print management workflow together with a job. Accordingly, a printing order reception system of a printing order reception firm, for example, can provide parameters indicating quality terms received from a customer to a system of a printing firm in a standardized predetermined format.


In the present exemplary embodiment, a description will be given of an example of using the above-described PRX as a data format for issuing a print quality requirement. By using such a standard format, it is possible to easily transmit quality terms between a plurality of different customers and printing firms. In addition, it becomes possible to compare the quality terms of different printed products.



FIG. 1 is a block diagram illustrating an overview of a printing system according to the present exemplary embodiment. A role of each apparatus and details of operation of the printing system will be described in detail with reference to FIG. 2 and subsequent diagrams. In FIG. 1, a parallelogram-shaped item indicates data. In the present exemplary embodiment, an order reception system server 110 serving as an information processing apparatus generates PRX data, and transmits the PRX data to a workflow management server 100. The workflow management server 100 analyzes the PRX data received from the order reception system server 110, and transmits print data, a job ticket, operation setting information, and a control instruction that are based on an analysis result to a production system 120. The workflow management server 100 is a control system that controls a printing apparatus to output a printed product satisfying a required print quality.



FIG. 2 is a diagram illustrating a configuration of a commercial printing system according to the present exemplary embodiment.


The workflow management server 100 is an apparatus that manages an entire workflow for a commercial printing product.


The workflow management server 100 receives, from the order reception system server 110, print data and PRX data, which is quality terms information. Then, the workflow management server 100 interprets the PRX data received from the order reception system server 110, and determines the production system 120 and executes prepress processing of the print data for each received job.


In addition, the workflow management server 100 generates data to be processed by the production system 120 (e.g., print data, a job ticket, operation setting information, and a control instruction that are illustrated in FIG. 1), and transmits the generated data to apparatuses included in the production system 120. The apparatuses included in the production system 120 will be described below.


Furthermore, based on information acquired from the apparatuses (control result illustrated in FIG. 1), the workflow management server 100 generates print quality exchange (PQX) data, and transmits the PQX data to the order reception system server 110.


In the present exemplary embodiment, the workflow management server 100 is described as an on-premises server installed at a site where workflow management is performed, but the workflow management server 100 is not limited to this.

A PRX analysis unit 521 analyzes PRX data received from the order reception system server 110, and identifies a print quality requirement and part of required prepress processing.


For example, the print quality requirement requires an average color difference obtained from measurement results of predetermined color patch images to fall within a specific standard. An example of the prepress processing is processing of adding the color patch images to be subjected to color measurement in color quality check processing to a margin of image data.


A process management unit 522 determines the production system 120 and issues a command to a prepress control unit 524 by using the product type information received from the order reception system server 110 and analysis result information from the PRX analysis unit 521.


Depending on product types, a product can include a plurality of types of parts. In such a case, the process management unit 522 generates a job for each part from one order.

The print control unit 541 also has an adjustment function of adjusting print quality, and executes the adjustment function based on a control instruction received from any of the workflow management server 100, the print server 122, and the production operator terminal 125.


The print control unit 541 includes a measurement control unit 5411. The measurement control unit 5411 executes measurement control using the measurement unit 322 based on a control instruction received from any of the workflow management server 100, the print server 122, and the production operator terminal 125.


A post-processing control unit 542 executes post-processing control based on a control instruction received from the workflow management server 100.


An inspection control unit 543 executes inspection control using the inspection apparatus 124 based on a control instruction received from the workflow management server 100.


The inspection control unit 543 compares image data read by a sensor included in the inspection apparatus 124 with reference image data. If a difference exceeding a predetermined acceptable range is detected as a result of comparison, the inspection control unit 543 identifies an inspection target object as a defective product and performs predetermined control such as notification to the user.


A data management unit 544 transmits information, such as control results of the various apparatuses included in the production system 120, to the workflow management server 100. Furthermore, the data management unit 544 transmits and receives other data to and from the various apparatuses. The data management unit 544 may be individually included in each of the apparatuses.


The color management unit 545 manages the color quality of a product output by using the printing apparatus 121 and the print server 122. More specifically, the color management unit 545 controls known color adjustment processing and color quality check processing.



FIG. 6 is a diagram illustrating an example of a UI displayed on the order reception system server 110 according to the present exemplary embodiment. When placing a printing order, the end user selects the type of a product to be created using a UI 601 illustrated in FIG. 6.



FIG. 7A is a diagram illustrating an example of a UI displayed on the order reception system server 110 according to the present exemplary embodiment. The UI is displayed on the order reception system server 110 by the end user pressing a quality detailed setting button 602 provided on the UI 601 illustrated in FIG. 6.


The end user can perform the detailed setting of quality terms for the quality of a printed product using a UI 703. For example, the end user can input a quality standard required for each job based on the standard of Japan Color. Thus, the end user can designate specific numerical values of an acceptable value and an ideal value of an average value of a color difference ΔE00 (CIE DE2000) between a colorimetric value of a produced printed product and a Japan Color specified value. As another example, the end user can specify a quality term of importance among a plurality of quality terms. Accordingly, the end user can set a quality term of particular importance to each print job.


As a method of designating a color difference between a standard color value such as a Japan Color specified value and a colorimetric value of a printed product, as illustrated in FIG. 7B, the user may be allowed to select any option from among a plurality of options for different quality levels. In the example illustrated in FIG. 7B, the level of the average value of the color difference ΔE00 (CIE DE2000) from the Japan Color specified value can be selected from among 3 or less, 5 or less, and 10 or less.



FIG. 8 is a flowchart illustrating software processing according to the present exemplary embodiment.


A control program of the flowchart illustrated in FIG. 8 is stored in a ROM 212 included in the order reception system server 110, loaded into a RAM 213 by a CPU 211, and executed by the CPU 211.


In step S801, the order reception unit 501 receives an order from the end user. The order includes PDF data serving as print data and a product type of a product. The product type is information indicating a type of a product that is predefined by the order reception system server 110. For example, the order reception system server 110 can define two product types, i.e., “Photo Book” and “Name Card”. The product type “Photo Book” indicates the type of a product for which a finished sheet size is set to A5 size, a bookbinding type is set to Perfect Binding, a sheet type of a body portion is set to “Glossy Paper”, and finishing of the body portion is set to “Lamination”. The product type “Name Card” indicates the type of a product for which a finished sheet size is set to “Name Card”, a bookbinding type is set to “No Bookbinding”, and a sheet type is set to “Quality Paper”. Such product types are provided so that the type of a product to be produced using the order reception system server 110, the workflow management server 100, and the production system 120 can be defined. In the present exemplary embodiment, a case is described where the end user selects the product type “Photo Book”. In the present exemplary embodiment, a configuration where the order reception system server 110 defines the product types is described, but the configuration is not limited to this. A configuration where a sales representative manually inputs an order from the end user may also be used.


The order reception unit 501 transmits, to the PRX generation unit 503, a product type of the product ordered from the end user via the UI 601. If the end user selects the product type “Photo Book” from among the product types, the order reception unit 501 transmits information indicating that the selection by the end user is the product type “Photo Book” to the PRX generation unit 503.


The PRX generation unit 503 generates PRX data based on the product type selected via the UI 601 and received from the order reception unit 501.


First, an overview of the PRX data to be generated in the processing will be described. As exemplified in FIG. 9, the PRX data includes requirements regarding quality such as MessageInfo, BusinessInfo, and QualitySpec.


The QualitySpec includes fields regarding quality specifications and an evaluation standard. BasisOfCalculation represents information regarding a calculating formula for deriving a score or a grade of print quality that is designated by a buyer. OverallGradingScale represents an overall score and a meaning and a range of the grade. MinimumAcceptableRank represents a lowest acceptable quality level. QualityParameterSet represents a score standard of each of color, registration, image defect, and barcode. QualityParameterSetType represents the type of a quality specification of color, registration, image defect, or barcode. QualityParameterSetName represents the name of a quality specification. ParameterSetScoringScale represents the definition of a score standard defined by a buyer. In the present exemplary embodiment, the information is described in a part of QualitySpec, but the configuration is not limited to this. Another field of the PRX may be used.


As a first example of QualityParameterSet, a color fluctuation inspection is performed by the print control unit 541. The print control unit 541 includes the measurement control unit 5411, and can monitor a color fluctuation of the production system 120 while producing a product. An example of printed color standard is Japan Color. The production system 120 satisfying the standard is verified that the quality of a printed product is a certain level or more.


In the present exemplary embodiment, the print control unit 541 performs the color fluctuation inspection by checking whether each job satisfies the Japan Color standard. The print control unit 541 inspects a printed product for a color fluctuation using an average value of the color difference ΔE00 (CIE DE2000) between the Japan Color specified value and a colorimetric value of the printed product produced by the production system 120. In this case, “Color Fluctuation Inspection” is set in the QualityParameterSetName, and “Color” is set in the QualityParameterSetType. In addition, the following terms are described in the ParameterSetScoringScale: “RankColor1” in DisplayLabel, “1” in Rank, and “Average ΔE is 4 or More” in ValueRange; “RankColor2” in DisplayLabel, “2” in Rank, and “Average ΔE is Less Than 4 and 3 or More” in ValueRange; and “RankColor3” in DisplayLabel, “3” in Rank, and “Average ΔE is Less Than 3” in ValueRange. The higher the numerical value of a rank is, the higher the quality is. In addition, by setting “2” in Rank in the MinimumAcceptableRank in the QualityParameterSet, the minimum quality level can be described. As a second example of QualityParameterSet, an appearance inspection of toner scattering is performed by an inspection apparatus. Before the production is started by the production system 120, a correct image is acquired with a camera included in the inspection apparatus, and the correct image is registered in the inspection apparatus. During the production, the inspection apparatus inspects toner scattering by acquiring an image of a printed result using the camera and comparing the image of the printed result with the correct image. In this case, “Scattering Inspection” is set in the QualityParameterSetName. Then, “Defects” is set in the QualityParameterSetType. In addition, the following terms are described in the ParameterSetScoringScale: “RankDefects1” in DisplayLabel, “1” in Rank, and “Scattering Diameter is 3 mm or More” in ValueRange; “RankDefects2” in DisplayLabel, “2” in Rank, and “Scattering Diameter is Less Than 3 mm and 2 mm or More” in ValueRange; and “RankDefects3” in DisplayLabel, “3” in Rank, and “Scattering Diameter is Less Than 2 mm” in ValueRange. The higher the numerical value of a rank is, the higher the quality is. In addition, by setting “2” in Rank in the MinimumAcceptableRank in the QualityParameterSet, the minimum quality level can be described. Using QualityParameterSet as described above, the rank of quality is calculated by the BasisOfCalculation. For example, a calculating formula for total quality that is based on the Ranks of the color fluctuation inspection and the scattering inspection is described in the BasisOfCalculation. For example, a calculating formula such as TotalRank=Rank(Color Fluctuation Inspection)*0.6+Rank(Scattering Inspection)*0.3 is described. TotalRank represents the total quality, and Rank(QualityParameterSetName) represents a Rank corresponding to QualityParameterSetName. The meaning of the rank of the quality that has been calculated using the above-described BasisOfCalculation is represented by the OverallGradingScale. The meanings of the ranks of the quality are described as the following: “Poor” in DisplayLabel, “1” in Rank, “Good” in DisplayLabel, “2” in Rank, “Excellent” in DisplayLabel, and “3” in Rank. The PRX data holding unit 5033 included in the PRX generation unit 503 holds the PRX data representing the above-described quality standards as fixed reference values.


In step S802, the PRX generation unit 503 acquires PRX data suitable for the ordered printed product among PRX data held by the PRX data holding unit 5033. For example, if the product type “Photo Book” is selected via the UI 601, the PRX generation unit 503 acquires PRX data for photo book from the PRX data holding unit 5033.


In step S803, the PRX generation unit 503 determines whether the end user has performed the detailed setting of quality terms for the ordered printed product. For example, if the user sets, as an average value of the color difference ΔE00 from the Japan Color specified value, a required ΔE00 average value to 3 or less and an ideal ΔE00 average value to 2 or less using the UI 701, it is determined that a detailed printing condition setting is performed. If it is determined that the detailed printing condition setting is performed (YES in step S803), the processing proceeds to step S804. If it is determined that the detailed printing condition setting is not performed (NO in step S803), the processing proceeds to step S805. In step S805, the PRX data acquired in step S802 is transmitted to the workflow management server 100.


In step S804, the quality requirement generation unit 5032 reflects the detailed setting of quality terms in the PRX data acquired in step S802. In the present exemplary embodiment, the description will be given of an example case in which the user sets, as an average value of the color difference ΔE00 from the Japan Color specified value, a required ΔE00 average value to less than 3 and an ideal ΔE00 average value to less than 2 using the UI 701. The quality requirement generation unit 5032 performs editing processing on the quality terms in which the following terms are set: “Color Fluctuation Inspection” in QualityParameterSetName, and “Color” in QualityParameterSetType of the PRX data acquired in step S802.


As illustrated in PRX data for photo book 1001 in FIG. 10A, standard quality requirements for a photo book are preset in QualityParameterSet. The following terms are set in the ParameterSetScoringScale: “RankColor1” in DisplayLabel, “1” in Rank, “ΔE00 Average Value is 4 or More” in ValueRange, “RankColor2” in DisplayLabel, “2” in Rank, “E00 Average Value is Less Than 4 and 3 or More” in ValueRange, “RankColor3” in DisplayLabel, “3” in Rank, “ΔE00 Average Value is Less Than 3” in ValueRange, and “2” in Rank set in MinimumAcceptableRank.


The parameters in the PRX data are changed as illustrated in edited PRX data 1002 in FIG. 10. More specifically, the parameters are changed as follows: “RankColor1” in DisplayLabel, “1” in Rank, “ΔE00 Average Value is 3 or More” in ValueRange, “RankColor2” in DisplayLabel, “2” in Rank, “ΔE00 Average Value is Less Than 3 and 2 or More” in ValueRange, “RankColor3” in DisplayLabel, “3” in Rank, “ΔE00 Average Value is Less Than 2” in ValueRange, “2” in Rank set in MinimumAcceptableRank of the QualityParameterSet, and “3” in Rank set in DesiredRank.


The DesiredRank in the PRX can represent a quality standard expected by the user. By using the DesiredRank, it becomes possible to notify the workflow management server 100 of an ideal quality standard expected by the end user together with the minimum quality standard. Accordingly, it becomes possible for a printing firm to achieve higher customer satisfaction measurement.


As another example, the description will also be given of a case where the user sets an important quality term using the UI 701. As stated in the above description of the PRX data, the rank of quality of a printed product that is based on a plurality of quality terms can be calculated using the BasisOfCalculation. For example, a calculating formula for total quality that is based on the ranks of the color fluctuation inspection and the scattering inspection is described in the BasisOfCalculation. For example, as illustrated in PRX data for photo book 1101 in FIG. 11, a calculating formula like “TotalRank=Rank(color fluctuation inspection)*0.6+Rank(scattering inspection)*0.3” is described in the PRX data as a standard quality setting for a photo book. If the user sets image defect as the important quality term in this case using the UI 701, the value of a weighting of the scattering inspection in the calculating formula included in the BasisOfCalculation is changed to a smaller value. In the present exemplary embodiment, setting image defect as the important quality term means lowering an acceptable level of image defect. For example, setting image defect as the important quality term means tightening a standard of the toner scattering inspection as the image defect. For example, as illustrated in edited PRX data 1102 in FIG. 11, the calculating formula is changed to “TotalRank=Rank(Color Fluctuation Inspection)*0.6+Rank(Scattering Inspection)*0.1”. To heighten the rank set in the OverallGradingScale by changing the calculating formula in this manner, an inspection result of the scattering inspection desirably indicates quality higher than the standard quality standard in such a manner as to satisfy a quality requirement as the entire printed product. Thus, it becomes possible to conduct an inspection using a stricter standard for the setting of an important quality term of the end user. In step S805, the PRX generation unit 503 transmits the PRX data edited in step S804 to the workflow management server 100.


In the present exemplary embodiment, the description has been given of the detailed setting of a color difference from Japan Color being a standard color. Alternatively, detailed settings regarding an image positional shift caused by elution of a sheet, readability of a barcode, or an image defect may be received and reflected. In addition, the structure of the PRX data illustrated in FIGS. 10A, 10B, 11A, and 11B is not limited to an extensible markup language (XML) format. In addition, a description method of a parameter describing each of the quality terms and a description method of a calculating formula may use another format such as a method that uses a mathematical formula.


In the present exemplary embodiment, the CPU 211 of the order reception system server 110 performs display control to display, on a display unit, a user interface for prompting the user to select a print quality setting of print data from among predetermined options. For example, as illustrated in FIG. 7A, a user interface for prompting the user to select an item to be prioritized, from among a plurality of items related to print quality, is displayed on the display unit. The plurality of items related to print quality includes barcode accuracy, registration accuracy, image quality, and the level of an acceptable image defect. From among these items, the user selects an item to be prioritized.


In the present exemplary embodiment, only by the user selecting an item from options, quality requirement data is automatically generated. For example, by setting a weighting of the item selected by the user as an item to be prioritized to a value larger than values of weightings of other items, a total value (e.g., TotalRank in FIG. 11) indicating a total print quality of a printed product is generated. In particular, the quality requirement data is generated in conformity to a format such as PRX that can be used in a plurality of printing control systems. Accordingly, the user does not have to generate a quality requirement compliant with a predetermined format, and a printing request convenient for the user can be received.


Moreover, in the present exemplary embodiment, by providing an order reception system with a setting unit of a detailed quality requirement aside from a setting unit of a normal print setting, it becomes possible to receive the detailed quality requirement from the end user even in a printing order reception environment in which a quality standard fixed for each order type is used.
