The present invention relates to quality requirements on a print product.
In the field of commercial printing, it is conceivable that information on requirements and a report on the quality of a product for which a customer makes a request of a printing company is desired to be electronically exchanged. Standards, such as PQX/PRX (Print Quality eXchange, Print Request eXchange) and JDF (Job Definition Format), are examples of the specifications for achieving the above. A series of processes in which a customer transmits by PRX requirements on the quality of a product required of a printing company and the printing company reports the quality of a product produced to the customer by PQX is electronized.
PTL 1 describes how to set points (representative points) to compare image data.
At the time of providing requirements on quality, a customer needs to designate where the quality of a product is inspected.
For example, PRX that is an example of quality requirements data has specifications to designate an inspection position by coordinates. In other words, when arrangement of images of print data is changed, there is a problem that, even when only the arrangement of images is changed without changing the images, an inspection position needs to be designated again each time. In addition, a customer is also not able to flexibly designate an inspection target of a product.
In light of the above problem, it is an object of the present invention to provide a technology for a customer to be able to flexibly designate an inspection target of a product.
To achieve the above object, an information processing apparatus of the present invention includes acquisition means configured to acquire instruction information on quality inspection of a printed matter, determining means configured to determine whether the instruction information designates an inspection target by identification information of an object or by coordinate information, and inspection means configured to identify an inspection position in accordance with the determination result and perform quality inspection of the printed matter by using the identified inspection position.
Further features of the present invention will become apparent from the following description of exemplary embodiments with reference to the attached drawings.
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments do not limit the invention described in the appended claims. Not all combinations of features that will be described in the embodiments are indispensable for solutions of the invention.

The work flow control unit 707 is a functional unit of the information processing apparatus 102 in the printing company system 100 and is a functional unit for providing a work flow function. Under command of the work flow control unit 707, various apparatuses shown in
The print control unit further includes a job execution unit 812 and the PDF function program 407. The job execution unit is made up of an image generating unit 813 and a print setting unit 814. The print setting unit receives job data, that is, JDF 809, PDF 808, and PRX, transmitted from the job registration request unit 806 and provides an instruction for an image generating process to the image generating unit 813. The print setting unit also provides an instruction for a process of analyzing the received PDF 808 to the PDF function program 407. The print setting unit 814 provides an instruction to the inspection unit 214 to perform inspection for quality requirements items of the PRX 810 required for a product produced. The PDF function program 407 transmits intermediate data (not shown) generated after analysis to the image generating unit 813 and executes the following image forming process. In other words, the image generating unit 813 provides an instruction for the size and count by type of sheets used in a print process to the sheet count program 409, and executes a process of forming an image of intermediate data (not shown) generated after analysis on the printing unit 815. The inspection unit 214 executes a process of inspecting an image generated on a sheet by the printing unit 815 and registers the result in the quality report creation unit 817.
A post-processing unit 905 is further installed on the downstream end of the inspection unit 904. In the post-processing unit 905, printed sheets are subjected to processing, including a binding process, such as stapling, a perforating process, such as punching, and the like. One example of the type, number, and connection order of constituent apparatuses that make up the image forming apparatus 104 shown in the drawing is shown; however, the configuration is not limited to the example shown in the drawing.
A third inspection unit 912 and a fourth inspection unit 913 are further placed in the conveying path 906 downstream of the first inspection unit 907 and the second inspection unit 908. The third inspection unit 912 and the fourth inspection unit 913 each are a spectrophotometric colorimetry apparatus. The third inspection unit 912 and the fourth inspection unit 913, as well as the first inspection unit 907 and the second inspection unit 908, are respectively placed above and below the conveying path 906 so as to be capable of detecting the front and back surfaces of a sheet at the same time. The third inspection unit 912 and the fourth inspection unit 913 are intended to accurately inspect color information of an image at a specific point on a sheet conveyed to the conveying path 906.
A sheet having passed through the first to fourth inspection units (907, 908, 912, 913) is further conveyed in the following two-way directions depending on the position of a flapper 909. In other words, a sheet passes through a conveying path 910 and further conveyed to the post-processing unit 905 corresponding to a portion on the downstream end of the inspection unit 904. Alternatively, when a conveyed sheet is not part of a product but a sheet of collateral test print intended to check tint and an image condition, it is not a good idea to mix the sheet with a product. Therefore, the inspection unit 904 is also capable of controlling the position of the flapper 909 such that a sheet is conveyed to a conveying path 911 and guided to a discharge tray 914.
Registration marks 917 are markers for inspecting whether an image is properly formed in a designated position on a sheet. This image information is read by the first inspection unit 907 and the second inspection unit 908. Even when registration marks 917 are not included as image information 915 of PDF data submitted by PRX, the image forming apparatus 104 is capable of forming an image by superposing registration marks on PDF data. Alternatively, registration marks can be included as image information in advance in submitted PDF data as in the case of second registration marks 918, and, in this case, the first inspection unit 907 and the second inspection unit 908 are capable of reading the registration marks 918 included in PDF data.
Color patches 916 are patch image parts for highly accurately reading color information at those points for an image at a designated position on a sheet with the third inspection unit 912 and the fourth inspection unit 913. Even when color patches 916, as in the case of the registration marks 917, are not included as image information 915 of PDF data submitted by PRX to the image forming apparatus 104, the image forming apparatus 104 is capable of forming an image by superposing registration marks on PDF data. It is also possible to perform colorimetry by reading an object, such as an image, included in PDF data. In this case, a color patch, as in the case of a second color patch 919, may be included as image information in advance in submitted PDF data, and not a color patch but an image of a product itself may be used as a target subjected to colorimetry. In the inspection unit 904, when the position of an image to be inspected is designated by coordinates, the third inspection unit 912 and the fourth inspection unit 913 are able to read a printed part of an object to be measured.
An image defect 922 is not included in image information 915 of submitted PDF data and represents a defective image part produced by a defect of the image forming apparatus 104 or a sheet. The image defect 922 is also able to be detected by the first inspection unit 907 and the second inspection unit 908, and the position of a detected defect is able to be acquired as relative coordinates (X1 (923), Y1 (924)) from the origin 921.
Registration marks 917 are set by a registration mark setting section 1013. When the registration mark setting section 1013 is used to provide an instruction to add registration marks to an image, the registration marks 917 are added to a setting target page of a PDF file. It is possible to add color patches 916 to a setting target page of a PDF file with a color patch setting section 1012.
A registration mark detail setting section 1015 and a color patch detail setting section 1014 are setting sections for setting detailed information, such as positions at the time when color patches 916 or registration marks 917 are added to an image. When, for example, these registration marks 917 or color patches 916 are superposed in an area of image information 915 of PDF, the original image is not obtained, so it is inconvenient. Therefore, the application in the present embodiment allows settings such that the positions of the color patches 916 or the registration marks 917 do not overlap the area of the image information 915 of PDF and coordinates of the image position are adjustable by these means.
Objects 931, 932, 933 are objects respectively having IDs with values of “5 0 obj”, “7 0 obj”, and “3 0 obj”. The ID of an object is a unique value automatically assigned by an application that creates PDF or given by a user. The ID of an object is a value that does not change depending on the position of the object in PDF. Therefore, when an object ID is designated in inspection position designation of PRX (described later), it is not necessary to designate again an inspection position even when the position of an object is edited after setting.
An object context menu 934 is a menu of operation to an object displayed when right-click operation is performed in a state where the object is selected. The object context menu 934 includes an inspection setting button for designating an inspection position for a selected object. When the inspection setting button is selected, a reference value of the ID of a selected object is added to an object select section 1042 of a PRX setting section 1003 (described later).
An output intent setting section 1009 is a setting section for output intent information, implemented by a PDF edit function. The output intent setting section 1009 is made up of an image formation process information setting section 1010 used by an image forming means applied during production and a color intent setting section 1011 applied to an image produced. These pieces of output intent information are configured to be able to be individually set page by page in combination with the page select section 1006.
A master information setting section 1020 is a setting section to input various master information needed at the time of creating PRX. Master information corresponds to various pieces of information including a date and company information required by the specifications of PRX, a name given to requirements specifications defined by PRX, and the like. These pieces of information are able to be edited by depressing a master information edit section 1021.
An integrated quality target setting section 1022 is a setting section for integrating at least one or more different types of quality requirements designated by PRX and defining an integrated quality level. Integrated quality is determined according to the following regulations. In other words, integrated quality is defined by a combination of a label 1023 that is readable information given to a quality level, a rank 1024 that is quantitative numeric value information corresponding to the label 1023, a value 1025 that defines a parameter and an expression for determining the rank 1024.
Specifically, details will be described below by using top-level quality 1031 as an example. The label of the top-level quality 1031 is defined as “Excellent”. Strings applied to these labels 1023 are able to be optionally set by the user 701 who uses the application shown in the drawing, operating on the information processing apparatus 110 in the customer system 109, that is, a customer. In other words, those strings are information provided in order for an operator to be able to easily determine the meaning of defined quality level and have properties different from information used in control and the like.
On the other hand, the rank 1024 of the top-level quality 1031 is defined as 10. This is a numeric value defined by a customer in order to quantitatively determine and manage the quality of a product for which the customer makes a request of a printing company and is information intended to be used in control and the like. However, the numeric value itself of the rank 1024 is able to be optionally defined by the customer as a quantitative numeric value of the quality of a product of its own.
An example in which a value 1025 for defining the rank 1024 of the top-level quality 1031 is “GT 8” is shown in the drawing. When the numeric value of a quantitative quality index, obtained from a defined evaluation formula, is greater than or equal to eight, the rank 1024 of the top-level quality 1031 is calculated as 10, and the quality of the product is determined as top-level quality.
The other quality levels are also defined such that the ranks and the labels “Good” 1032, “Acceptable” 1033, and “Poor” 1034, are uniquely determined according to similar numeric values and values calculated from the mathematical expression. For the quality levels, a configuration that information defined by a quality level edit section 1026 can be edited is adopted in the present embodiment.
The number of quality levels can be set optionally. In other words, where necessary, when more detailed levels are designated, a new quality level is able to be added to the integrated quality target setting section 1022 by depressing a level add section 1028. In addition, levels with a checkmark are able to be deleted with a level delete section 1027.
When a customer provides quality requirements to a printing company, the customer defines acceptable conditions depending on the numeric value of the rank 1024 defined by the quality level for the quality of a produced product. The acceptable conditions are defined by using a minimum acceptable quality setting section 1029 and a desired quality setting section 1030.
The minimum acceptable quality setting section 1029 is used for a customer to define acceptable quality, that is, the minimum value of the rank 1024, at the time of delivery of a product for a printing company. In other words, it is possible to communicate quality requirements to a printing company that a product with a numeric value of the rank 1024 below the numeric value defined in the minimum acceptable quality setting section 1029, that is, eight in the example of the drawing, does not satisfy acceptable quality.
The desired quality setting section 1030 is used for a customer to define desired quality conditions, that is, the desired value of the rank 1024, at the time of delivery of a product for a printing company. In other words, it is possible to communicate a product with a numeric value of the rank 1024 above the numeric value defined in the desired quality setting section 1030, that is, nine in the example of the drawing, as quality requirements to a printing company.
An image misregistration quality setting section 1035 also defines acceptable conditions depending on the numeric value of the rank 1024 defined by the above-described quality level for image misregistration quality of a product at the time of providing quality requirements on image misregistration. Acceptable conditions are defined by the minimum acceptable image misregistration quality setting section 1037 and a desired image misregistration quality setting section 1038 on image misregistration quality.
The image misregistration quality setting section 1035 is a setting section to input quality requirements information on image misregistration of a product at the time of creating PRX. As in the case of the integrated quality target setting section 1022, the image misregistration quality setting section 1035 is configured to be able to designate the level of quality requirements on image misregistration with a means to set the label 1023 and the rank 1024.
An image misregistration quality value 1036 is defined with reference to a deviation (length or a distance between a reference image and an image of a product) from a reference position that is a measurement result of a product with respect to a required image misregistration. In other words, an example in which top-level quality 1039 in image misregistration quality is less than or equal to a deviation of 0.002 mm is shown. In other words, the drawing shows an example in which the label 1023 in the case of the top-level quality 1039 is “Excellent” and the rank is 10. Similarly, the drawing shows an example in which “Acceptable” 1040 and “Poor” 1041 in image misregistration quality are similarly defined. A function to add and delete a rank is implemented by a mechanism similar to the integrated quality target setting section 1022, so the description is omitted.
A minimum acceptable image misregistration quality setting section 1037 is a setting section with which a customer defines acceptable image misregistration quality, that is, the minimum value of the rank 1024, at the time of delivery of a product for a printing company. It is possible to communicate image misregistration quality requirements to a printing company that a product with a numeric value of the rank 1024 below the numeric value defined by the minimum acceptable image misregistration quality setting section 1037, that is, five in the example of the drawing, does not satisfy acceptable image misregistration quality.
A desired image misregistration quality setting section 1038 is a setting section with which a customer defines desired image misregistration quality conditions, that is, the desired value of the rank 1024, at the time of delivery of a product for a printing company. It is possible to communicate, to a printing company, image misregistration quality requirements on a product with a numeric value of the rank 1024 above the numeric value defined in the desired image misregistration quality setting section 1038, that is, 10 in the example of the drawing.
The object select section 1042 is an area to display a button for selecting an object to be designated as an inspection position. The reference value of the ID of the object for which the inspection setting button is selected in the object context menu 934 is displayed in the object select section 1042. The drawing shows a state where “5 0 R” button 1043 that is a button corresponding to the reference value “5 0 obj” is selected. The display may be switched to the screen at the timing at which the inspection setting button is selected. Inspection of color is representatively described in the description of the embodiment; however, it may be used to designate an inspection position for other than color.
A target image display area 1044 is an area to display the image of an object selected in the object select section 1042.
A reference data select button 1045 is a button for selecting data of a comparative reference to evaluate an inspection result of the object selected in the object select section 1042. In the case of inspection of color, color reference data is selected. The reference data select button 1045 becomes selectable only when a button corresponding to the reference value of any one of objects is selected in the object select section 1042. When the reference data select button 1045 is selected, a file select screen (not shown) is displayed, and a file can be selected.
A color quality setting section 1046 is a setting section to, at the time of creating PRX, input quality requirements information on the color of a product. As in the case of the integrated quality target setting section 1022, the color quality setting section 1046 is configured to be able to designate the level of quality requirements on color with a means to set the label 1023 and the rank 1024.
A color quality value 1047 defines a color difference (also referred to as ΔE or delta E) of a color value that is a measurement result of a product for a required color as a reference. In other words, an example in which top-level quality 1048 in color quality is less than or equal to a color difference of 1.0 is shown. In other words, the drawing shows an example in which the label 1023 in the case of the top-level quality 1048 is “Excellent” and the rank is 10. Similarly, the drawing shows an example in which “Good” 1049, “Acceptable” 1050, and “Poor” 1051 in color quality are similarly defined. A function to add and delete a rank is implemented by a mechanism similar to the integrated quality target setting section 1022.
The color quality setting section 1046 also defines acceptable conditions depending on the numeric value of the rank 1024 defined by the above-described quality level for color quality of a produced product at the time when a customer provides quality requirements on color to a printing company. Acceptable conditions are defined by a minimum acceptable color quality setting section 1053 and a desired color quality setting section 1054 on color quality.
The minimum acceptable color quality setting section 1053 is used for a customer to define acceptable color quality, that is, the minimum value of the rank 1024, at the time of delivery of a product for a printing company. In other words, it is possible to communicate color quality requirements to a printing company that a product with a numeric value of the rank 1024 below the numeric value defined in the minimum acceptable color quality setting section 1053, that is, eight in the example of the drawing, does not satisfy acceptable color quality.
The desired color quality setting section 1054 is used for a customer to define desired color quality conditions, that is, the desired value of the rank 1024, at the time of delivery of a product for a printing company. In other words, it is possible to communicate, to a printing company, color quality requirements on a product with a numeric value of the rank 1024 above the numeric value defined in the desired color quality setting section 1054, that is, 10 in the example of the drawing.
As shown in the drawing, the media setting section 1061 is made up of a global job media setting section 1066 and a partition job media setting section 1068. The global job media setting section 1066 is provided to select a piece of media used in a job. In other words, the example shown in the drawing shows a state where “Media1” is selected in a global job media species select section 1067. In other words, it means that, in executing a print process with this JDF, a piece of media used during printing is set to “Media1”. On the other hand, the partition job media setting section 1068 is a setting means to be used in the case where a piece of media different from a piece of media set in the global job media setting section 1066 is set for a specific page or page range. In the example shown in the drawing, the partition job media setting section 1068 provides a means to create and delete a page range to be set with a page range add section 1069, checkboxes 1046, and a page range delete section 1070, to be set.
In the drawing, a state where two page ranges are created is shown. In a first page range setting section 1071, page 5, page 200 to page 210, and page 250 are targets to be set in a first page range 1073. Then, an example in which a piece of media to be used for pages to be set to “Media2 (coated)” in a first partition media select section 1074 is shown.
In a second page range setting section 1072, an example in the case where page 1 is a target to be set in a second page range 1075 and a piece of media to be used for the page to be set is set to “Media3 (cardboard)” in a second partition media select section 1076 is shown.

In S1310, the controller unit 205 acquires the object ID and count stored in association with the inspection position. After acquisition, the process proceeds to S1311.
In S1310, the controller unit 205 creates an inspection result by using the object ID. The inspection result has been described with reference to
In S1312, the controller unit 205 transmits the inspection result to the information processing apparatus 102. Transmission of the inspection result has been described in connection with the first transmission program 405 of
A continuous form sheet inspection position correspondence table 2000 is a table for storing an inspection position in a printer that handles a continuous form sheet in association with identification information of an object. An object ID 2001 and a count 2002 indicating the number of prints of the object are stored as identification information of the object, and a print position 2003 of the object on a continuous form sheet is stored as an inspection position.
A cut sheet inspection position correspondence table 2010 is a table for storing an inspection position in a printer that handles a cut sheet in association with identification information of an object. Identification information of an object is the same as in the case of a continuous form sheet; however, a sheet count 2011 indicating what number of sheet the inspection position is on and a print position 2012 of an object on a cut sheet.
As described above, the inspection unit 214 handles a position to perform inspection by a position on a printed matter. On the other hand, when an inspection result is transmitted to the information processing apparatus 102, the inspection result becomes identification information of the object as shown in

By similar calculation, even with any print settings or any PDF, it is possible to calculate the position of an object on printed paper from information on imposition setting, PDF page information, and position information of the object.
Since PQX that reports quality has specifications in which an inspection position is described by coordinates, it has not been clear what is the result of measurement in the case of object designation. In other words, when arrangement is different even for the same inspection target, PQX describes results for different coordinates, so it has been difficult to reference the report. In contrast, according to the present embodiment, a quality report is also described in association with identification information of an object to be inspected, with the result that it is clear what a quality report is made on.
As described above, the image forming apparatus according to the present embodiment is capable of designating an inspection position by an object ID in PDF, with the result that time and effort to create quality requirements again are omitted even when the position of an object changes. Furthermore, a customer is able to designate an inspection position not only by an object ID but also by coordinates and is able to acquire quality report data with a description method corresponding to designation, so it is easy to perform checking. When the result of quality measurement designated by an object ID is stored in association with the object ID and is provided as notification, which object is measured to obtain the inspection result is easily identified.
The first embodiment is applicable only when the inspection apparatus is an in-line apparatus. A second embodiment provides a configuration that can be implemented even with an off-line inspection apparatus. Portions common to the first embodiment will not be described.
An inspection apparatus 1401 is an off-line inspection apparatus, that is, an independent inspection apparatus not connected to the image forming apparatus 104. Here, it is assumed that the inspection apparatus 1401 is connected to the information processing apparatus 102 via a network and is able to receive an inspection instruction from the work flow control unit 707. The inspection apparatus 1401 may be not connected to the information processing apparatus 102 and may be configured to receive an inspection instruction by using a barcode or the like.
An inspection control unit 1402 is a portion that controls the operations of the inspection apparatus 1401.
In S1403, the work flow control unit 707 generates a print job to the print control unit 708 that is a component of the image forming apparatus 104. The print job does not include execution of inspection.
In S1404, the print control unit 708 starts a print process. After the print completes, a table that stores the correspondence between identification information of an object and a print position, created during analysis of PDF data, that is, information corresponding to
In S1405, the print control unit 708 provides an inspection instruction to the inspection control unit 1402. The inspection position designated by the ID of an object in quality requirements is converted to an inspection position that is coordinates on a printed matter by referencing the data stored in the RAM 302 in S1404, that is, the data shown in
In S1406, the inspection control unit 1402 transmits an inspection result to the work flow control unit 707. The inspection result is created in association with the inspection position included in the inspection instruction received in S1405. The description will be made with reference to
In S1407, the print control unit 708 converts the inspection position included in the inspection result received in S1406 to identification information of an object by referencing the data stored in the RAM 302 in S1404, that is, the data shown in
A continuous form sheet inspection result 1500 shows an example of an inspection result for a continuous form sheet.
A continuous form sheet inspection position 1501 is that an inspection position at which inspection is performed is indicated by coordinates on a printed matter. When the inspection position corresponding to the coordinates shown here is stored in the continuous form sheet inspection position correspondence table 2000, it indicates that the inspection position in quality requirements is the result of inspection designated by object ID.
A cut sheet inspection result 1510 shows an example of an inspection result for a cut sheet.
A sheet count 1511 is a value indicating a sheet on which inspection is performed. A cut sheet inspection position 1512 is that an inspection position at which inspection is performed is indicated by coordinates on a printed matter. By referencing two values, an inspection position on a printed matter can be uniquely identified. When the inspection position corresponding to the sheet count and the coordinates, shown here, are stored in the cut sheet inspection position correspondence table 2010, it indicates that the inspection position in quality requirements is the result of inspection designated by object ID.
As described above, in the system described in the present embodiment, the work flow control unit 707 takes correspondence of inspection position between the identifier of an object designated as an inspection position in quality requirements and an inspection position on a printed matter. Thus, even when the off-line inspection apparatus performs inspection, it is possible to designate an inspection position by object ID.
In the first and second embodiments, the image forming apparatus 104 performs ripping of PDF and creates correspondence between an object ID and an inspection position. A third embodiment describes an embodiment in which the information processing apparatus 110 is configured to execute a rip process.
In the first and second embodiments, it is not necessary to designate an inspection position again even when the position of an object is changed in the same PDF; however, it is necessary to designate an object again even when the same object ID is used in different PDFs. The third embodiment describes an embodiment in which it is not necessary to designate an object again even in different PDFs.
Object ID column 1601, inspection details column 1602, reference data column 1603, and evaluation data column 1604 respectively store the ID of an object to be inspected, the details of inspection to be performed, a file name of data referenced to evaluate an inspection result, and evaluation data. Evaluation data includes label, rank, and value that are criteria of evaluation. In the row of the object ID “5 0 R” in

In S1902, the CPU 301 analyzes JDF with the JDF function program 1801, and stores the analyzed result in the RAM 302 in association with identification information of a job. After memory, the process proceeds to S1903.
In S1903, the CPU 301 analyzes PRX (quality requirements data) with the quality requirements receiving program 507 and stores the analyzed result in the RAM 302 in association with the identification information of the job. After memory, the process proceeds to S1904.
In S1904, the CPU 301 analyzes PDF data with the PDF function program 1802, and stores the analyzed result in the RAM 302 or the HDD 311 in association with the identification information of the job. After memory, the process proceeds to S1905.
In S1905, the CPU 301 determines whether a quality measurement position is designated by object ID or designated by coordinates in the PRX analyzed in S1903. When the quality measurement position is designated by object ID, the process proceeds to S1907. When the quality measurement position is designated by coordinates, the process proceeds to S1913.
In S1905, the CPU 301 calculates a point on an object as an inspection position from imposition acquired by analysis of the JDF, and the object ID and PDF coordinates of the object, acquired by analysis of the PDF. Calculation of an inspection position will be described with reference to
In S1908, the CPU 301 provides a print instruction to the image forming apparatus 104 and transmits the analyzed result of the JDF, the analyzed result of the PDF, and the analyzed result of the PRX. At this time, the inspection position is designated by the inspection position on a printed matter, acquired in S1907. When the inspection apparatus is an off-line apparatus, it is not necessary to transmit the analyzed result of the PRX.
In S1909, printing and inspection end in the image forming apparatus 104, and the CPU 301 receives the inspection result of
In S1910, the CPU 301 determines whether there is an object corresponding to the inspection position described in the inspection result received in S1909. The table shown in
In S1911, the CPU 301 acquires the identification information of the object corresponding to the inspection position on a printed matter. When the identification information of the object is acquired, the process proceeds to S1912.
In S1912, the CPU 301 creates a report. The report is PQX described with reference to
As described above, the system described in the present embodiment allows to designate an inspection position by object ID even with a configuration to execute a rip process in the information processing apparatus 110. By storing the ID of an object and information on a quality inspection performed on the that object in association with each other, it is possible to perform quality inspection without resetting quality inspection even for different PDFs.
