The inspection device performs decoding of the image data printed on the printed matter, and decides a reading range of the printed matter based on the acquired position.

Description

  The present invention relates to a printing system including a printing apparatus that performs variable printing with layout change, and an inspection apparatus that performs inspection confirmation of printed matter, and a control method thereof.

  In a printing apparatus that performs variable printing (variable printing), a print image page that combines a print object with a fixed print content, a variable template that defines a variable print object, and record information stored in a database referenced from the print template. Generate data. This page data image has a plurality of pages of image data for printing having the same print format and different print contents for each record in one print job.

  There is no possibility that the print contents defined as the fixed print object in the variable template are changed between the prints corresponding to each record information printed in such an apparatus, and only the print contents in the variable print object may be different. .

  Further, as a printed matter inspection process, the printed matter inspection apparatus reads the printed content as an image, and determines that the printed matter is correctly printed if it matches the page data at the time of printing. In the inspection device used in combination with the variable printing device, in order to shorten the inspection processing time, the image and the record information are compared only for the area printed as the variable print object defined by the variable template. Do. Then, it is confirmed whether or not the printing is correctly performed. The inspection apparatus assumes that the printed matter is correctly printed if the content printed in the area of the variable print object is the same as the previous record information referenced when generating the image of the variable print object area.

  As a prior art of the inspection device, for a job in which the position of the image area to be inspected differs for each record in one print job, the printing device transmits the processing result in the layout process or the printing process to the inspection device through the network line The technique to do is disclosed by patent document 1. FIG. Upon receipt of the processing information, the inspection apparatus determines an area to be inspected of the printed product image during the inspection process, and compares the images.

  On the other hand, as another conventional technique, there is a paper-cut printing as a technique for reducing the number of print pages by changing the position of a print object such as an image or text in a print area in order to save the number of sheets used for printing. Spam printing is a type of layout change process. By applying this processing, the print object is moved to one side of the paper to create a blank area without the print object in the page. By placing a movable print object that exists on a subsequent page in the created blank area, the object is printed on a page before the page that should be printed. As a result, the blank area increases in the latter half of the page, and the page can be reduced as a whole by not printing this blank area. Alternatively, it is possible to print on a smaller size paper with the same contents by reducing the print area of the image by the margin area for each page.

JP2010-146374

  Assume a printing system including a variable printing apparatus having a variable printing function and a squeeze printing function shown in the prior art, and an inspection apparatus for inspecting printed matter. This printing system combines variable templates and record information for variable printing to generate page data for printing, and then performs a process of applying a thinning process to the page data. After the record information is combined with the variable print object of the variable template, the blank area is created in the reverse direction on the paper by bringing all the objects in a certain direction of the paper. In this case, the position of the area to be inspected after printing is not the position of the variable print object area defined by the variable template, and it is necessary to inspect the area moved from the area by the narrow-cut printing.

However, in an environment where the inspection apparatus described in Patent Document 1 is not connected to the variable printing apparatus via a network, the position of the variable print object to be inspected cannot be correctly transmitted to the inspection apparatus. In addition, it is not considered that the position of the inspection target is changed due to the movement of the object by the chamfered printing. Further, when the inspection apparatus does not support the transmission data format of the printing apparatus, the position of the variable print object that is the object of inspection processing cannot be correctly transmitted. In addition, there is a printing system in which information about inspection is written in a separate printed printing instruction document and transmitted to the inspection device. However, there is a possibility that the printed material must be handled separately from the printed material, resulting in a mistake in the printed material. .
An object of the present invention is to provide a printing system for solving at least one of the above-described problems.

  A printing system according to an embodiment of the present invention includes a fixed print object that is drawn in common for all records, and a variable print object that is drawn by being combined with record information for printing by changing the contents for each record. Based on the variable template and the record information stored in the storage means, the generation means for generating page data based on the record information prepared for each record, and the number of sheets used for printing In order to reduce, the position of the variable print object included in the page data is changed, and a culling unit that deletes a margin portion of the page data, and information on the position of the variable print object changed by the culling unit Encoded change processing result information including the changed image data expressed as image data by being encoded, A modified image in the printed matter read by the reading means, comprising: a synthesizer that synthesizes the page data from which the margin portion is deleted; and a synthesizer that generates the printed matter based on the synthesized page data. Decoding data, obtaining means for obtaining the position of the variable print object changed by the culling means, content of the printed matter printed within a range determined based on the obtained position, It is confirmed whether or not the record information stored in the storage means matches.

  In a printing system consisting of a variable printing device that performs variable printing with layout changes and an inspection device that inspects the printed matter, the variable content information that differs for each record information in the printed matter to be inspected is included in the printed content. The device acquires variable part information from the printed material. Thereby, the position of the area to be inspected can be appropriately determined.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

[First embodiment]
FIG. 1 is a schematic diagram of the proposed printing system 101. A record database 103 for storing record information; a variable printing apparatus 102 for combining the specified variable template and the record information acquired from the record database 103 to perform layout change processing of the combined page data and printing; and An inspection device 104 for inspecting printed matter printed by the variable printing device is connected via a network.

  A process of combining the layout change process result information with the page image and printing after the layout change process by the process of reducing the objects in the page by the variable printing apparatus 102 in the print system 101 will be described with reference to the flowchart of FIG.

  In step S <b> 201, the control unit 302 of the printing apparatus 301 illustrated by the variable printing apparatus 102 in FIG. 1 acquires record information of the database 103 from the communication unit 306 in step 201. The control unit 302 generates page data by combining the acquired record information with the variable template. As shown in FIG. 13, the variable template is composed of a fixed print object drawn in common for all records and a variable print object for changing the contents for each record. The variable print object has an ID for each object. In a database that stores record information prepared for each record, an ID is associated with each key attribute of the record database.

  In step S202, the control unit 302 refers to the key data corresponding to the ID of each variable print object included in the acquired record information, and combines the data with the variable print object. Data corresponding to each record information is combined with all the variable print objects in the page to generate page data for one record. This process is repeated for the number of records acquired. The generated page data is composed of a fixed print object defined in advance in the variable template and a print object data group arranged in the variable print object. The print object data group can change the position in the page data in units of objects.

  In step 203, the control unit 302 causes the layout processing unit 203 to perform a thinning process on the object data group synthesized in step 202, and causes the image generation unit 305 to generate a page image based on the result after application. The thinning process changes the position of the drawing object in the page data and moves it to one direction of the drawable area. By combining the drawn area and the non-drawn area, the paper used for printing Save the number. Although the drawing position of the object is changed by the thinning process, the same amount of information can be printed with a small number of pages by changing the position so as not to impair the readability of the reader. Note that each unit illustrated in FIG. 3 is realized by a CPU (Central Processing Unit) reading and executing a program for realizing each unit loaded in the memory.

  An outline of the procedure of the thinning process will be described with reference to FIG. Before the culling process, the print position of the variable part is standardized for all records according to the variable template, but after applying the culling process, the information content differs for each synthesized record. Page data in which the printing position of the variable part is different is generated.

  In step 204, the control unit 302 generates layout change process result information from the result of the thinning process performed in step 203. The layout change process result information has information indicating what position has been changed for each drawing object by the thinning process.

  FIG. 5 shows an example of layout change processing result information. The layout change processing result information in FIG. 5 includes an ID 502 that uniquely identifies an object included in the table 501, an object type 503 that indicates whether the object is a variable object, and a movable that indicates whether the object can be moved by the layout changing process. A key 504, coordinate values 505 before layout change processing is applied, and coordinate values 506 after layout change processing are applied. In step 205, the control unit 302 selects how the layout change processing result information generated in step 204 is printed on a sheet.

  When the layout change process result information is printed as visible barcode information, the process proceeds to step 206, and the control unit 302 causes the barcode data generation unit 307 to convert the layout change process result information into barcode data. After the conversion, the control unit 302 causes the image generation unit 305 to synthesize the converted barcode data with the blank portion of the page image so as not to overlap other object data. The bar code is a two-dimensional code, and includes a QR code, a glyph code, and other two-dimensionally expressed codes. The barcode image is a representation of the barcode as an image, and corresponds to a two-dimensional code image.

  When the layout change process result information is printed as digital watermark information, in step 208, the control unit 302 causes the watermark data generation unit 307 to convert the layout change process result information into digital watermark information. The contents of the digital watermark information actually printed on the paper are invisible. After the conversion, the control unit 302 causes the image generation unit 305 to synthesize the digital watermark information converted into a page image.

  When printing the layout change processing result information as registration mark information, in step 210, the control unit 302 causes the registration mark data generation unit 309 to convert the layout change processing result information into registration mark data. The registration mark data is visible and points to a rectangular area on which an object to be inspected is printed. After the conversion, the control unit 302 synthesizes the registration mark data converted by the image generation unit 305 with the outer area of the page image. After combining the layout change processing result information with the page image, in step 212, the control unit 302 causes the printing unit 304 to print the page image.

In the present embodiment, the layout change processing result information is expressed as image data and combined with page data. The image data of the layout change processing result information to be combined is referred to as changed image data. The process executed to express the layout change process result information as image data is referred to as encoding. In addition, the process executed to acquire the contents of the layout change process result information expressed as image data by being encoded is referred to as decoding.

  FIG. 4 is a flowchart showing the thinning process in the present embodiment. In step S <b> 401, the control unit 302 selects an object closest to the top side of the paper from the object group in the page. Next, in step 402, it is determined whether the object can be moved with respect to the upper side direction of the object sheet. If there is an area that can be moved without overlapping another object in the upper side direction of the sheet, it is determined that the object is movable in S403, and the object is moved to the movable area. If it is determined that it cannot be moved, the control unit 402 proceeds to step 404.

  When the control unit 302 finishes moving the object, in step 404, the control unit 302 searches for the next object from the object toward the bottom side of the sheet. If the thinning process is not applied to all the objects and there are other objects, the process returns to step 401, and the process is performed again on the objects found in step 404. When the control unit 302 completes the determination as to whether the thinning process is possible for all objects in the page, the control unit 302 ends the thinning process for the page.

  FIG. 6 illustrates the result of application of the above-described thinning process shown in the flowchart of FIG. In the page data before processing indicated by 601, layout change processing is performed for the print object group on the drawable area. Reference numeral 602 denotes the result of applying the thinning process to 601. Each object is moved in the direction of the top side of the paper to eliminate the margin in the vertical direction of the paper. As a result, a blank area is collected at the bottom of the sheet. If there is a subsequent page in the target page and it is not necessary to divide the page between the subsequent pages and print objects can be placed consecutively, the print object of the subsequent page is continued in the blank area. It is also possible to arrange. As a result, the number of pages can be reduced by deleting the blank portion of the entire variable print job.

  FIG. 7 shows an example of a print result obtained by printing a page data image obtained by combining the layout change process result information in the print process shown in step 212. Reference numeral 701 denotes a printed matter that is a printing result obtained by combining the barcode image with the blank portion of the page data in step 207. The barcode image 704 is a changed image obtained by converting the difference information before and after the change process of the variable print object whose position on the page data has been changed. By analyzing the changed image data, it is possible to specify a new position of the variable print object whose drawing position has been changed.

  Reference numeral 702 denotes a printed matter of page data obtained by synthesizing digital watermark information in step 209. The print object 705 combined with the digital watermark information includes information before and after the print object change process. The digital watermark information 705, that is, the watermark image, is a changed image obtained by converting the difference information before and after the change processing of the variable print object whose position on the page data is changed. In this embodiment, the watermark image is synthesized on the variable print object. However, the watermark image may be applied on at least one print object of the variable print object or the fixed print object. Reference numeral 703 denotes a printed matter of page data generated by the registration mark data synthesis process in step 211. The register mark information 703 indicates the rectangle of the object to be inspected.

  The inspection process of the inspection apparatus that inspects the sheet on which the page image including the layout change processing result information in the printing system is printed will be described with reference to the flowchart of FIG. 8 and FIG. Each unit illustrated in FIG. 9 is realized by the CPU reading and executing a program for realizing each unit loaded in the memory. In step S <b> 801, the control unit 902 of the inspection apparatus 901 illustrated by the inspection apparatus 104 in FIG. 1 reads an image of a printed material to be inspected printed by the variable printing apparatus 102 in the image acquisition unit 903.

  After acquiring the printed image, the control unit 902 acquires record information from the database 103 as a storage unit via the communication unit 905 as comparison source information corresponding to the page image acquired in step 801. In step 803, the control unit 902 reads the type of layout change processing result information combined with the page image from the printed material image acquired in step 801.

  In accordance with the type of layout change process result information acquired in step 803, the control unit 902 determines a means for acquiring layout change process result information. If the layout change processing result information is a barcode, in step 804, the control unit 902 causes the barcode data decoding unit 906 to decode the barcode data. The control unit 902 acquires layout change process result information included in the barcode data as a result of the decoding process.

  Similarly, when the layout change processing result information is a watermark image, in step 805, the control unit 902 causes the watermark data decoding unit 907 to perform the digital watermark data decoding process. The control unit 902 acquires layout change process result information included in the watermark data as a result of the decoding process. Based on the layout change processing result information obtained in step 904 and step 905, the control unit 902 obtains the position of the variable print object in the image data of the printed matter obtained in step 801, and determines the image range to be inspected. To do.

  When the layout change process result information is register mark information, the control unit 902 acquires the position of the register mark from the image. The variable print portion of the image data of the printed matter acquired in step 801 is acquired from the obtained registration mark information, and the image range to be inspected is determined.

  The control unit 902 compares the content printed in the image range determined based on the specified position with the record information acquired in step 802, and the print content of the variable part of the printed material matches the record information. Make sure that

  In a printing system 101 including a variable printing device 102 that performs variable printing with layout change and an inspection device 104 that inspects the printed matter, information on variable portions that differ for each record information in the printed matter to be inspected is printed. It can be included. As a result, the inspection apparatus can acquire information on the variable part from the printed matter and specify the range to be inspected accurately. More specifically, in variable printing, when a part where record information is recorded is inspected, even if the position of the object of the print data is moved by the ending process, an appropriate inspection process is performed. Become.

[Second Embodiment]
FIG. 7 is a diagram illustrating a process for determining a composite position in consideration of after the print process when the layout change process result information is combined with the page image and printed after the layout change process by the in-page object narrowing process in the printing system 101. This will be described with reference to the flowchart of FIG.

  In step S1002, the control unit 302 of the variable printing apparatus 102 generates page data by combining the record information acquired via the communication unit 306 in step 1001 with a variable template. In step 1003, the layout processing unit 303 performs the narrowing process on the combined page data, and generates layout change process result information from the information of the object whose position has been changed as a result of the narrowing process.

  In step 1005, the control unit 302 refers to the print setting of the page data and determines whether or not to perform the cutting process for the printed material after the printing process. The cutting process is used in the case where printing is performed in advance on a sheet having a size larger than the printed product, and the surroundings are trimmed by the size of the printed product, thereby improving the appearance. In this case, since the outside of the drawing area of the paper is cut, the content printed in that portion does not remain in the final product.

  After determining that the cutting process is to be executed, the control unit 302 determines whether it is possible to synthesize the changed image data in which the layout change process result information is represented by image data at the cutting position. When combining the changed image data as visible barcode data, if the cutting width is smaller than the barcode data area, it is determined that the barcode information cannot be drawn in the cutting area, and the combining is not performed. When the composition is not performed, the process proceeds to step 1009, and the control unit 302 determines whether or not the modified image data can be rendered in a blank area in the page data where no rendering object exists.

  When the changed image data is combined with the cut portion, in step 1007, the control unit 302 causes the barcode data generation unit 307 to generate barcode data as changed image data based on the layout change processing result information. Thereafter, the control unit 302 synthesizes the barcode data with the area to be deleted after the page data cutting process, in which it is determined in step 1005 that the barcode data can be synthesized.

  When the control unit 302 determines not to perform the cutting process in step 1005, the control unit 302 searches for a position where the layout change process result information in the page data can be combined, and in step 1009, a margin in the page data. Find an area.

  In step 1009, the control unit 302 determines whether or not it is possible to synthesize the changed image data in a blank area where no drawing object exists in the page data without overlapping the drawing object. At this time, the size of the visible barcode data is compared with the size of the margin area, and if the margin area is larger than the size of the barcode data, it is determined that synthesis is possible. The composition control unit 302 synthesizes the barcode data with the searched blank area. That is, when the changed image data expressed by the two-dimensional code image fits in the cut portion of the page data, the changed image data expressed by the two-dimensional code image is combined with the cut portion of the page data.

  In step 1022, the control unit 302 determines that there is no area in the page data where the layout change processing result information can be combined, and generates and synthesizes digital watermark data so that it can be drawn overlapping the existing drawing area. To do. That is, when the changed image data expressed by the two-dimensional code image fits in the cut portion of the page data, the changed image data expressed by the two-dimensional code image is not combined with the cut portion of the page data.

After combining the changed image data with the page data in any format, the control unit 302 causes the printing unit 304 to execute a printing process based on the page data, and the printing unit 304 generates a printed matter. After printing, an inspection process is performed on the printed matter. After inspection, the printed matter of page data for which cutting processing is set is subjected to cutting processing, and layout change processing result information drawn at the position of the paper to be cut and discarded is deleted.
With the layout change process described above, the layout change process result information can be reliably transmitted to the inspection apparatus, and the post-printing process can delete the combined information from the actual printing.

  When the cutting process is performed on the printed material by the above processing, the changed image data expressed by the two-dimensional code image is combined with the cutting portion of the page data corresponding to the portion of the printed material to be cut. In addition, when there is a margin part in which the changed image data can be combined with the page data in which the position of the variable print object has been changed by the thinning process when the cutting process is not performed, the margin part of the page data The modified image data expressed by the two-dimensional code image is synthesized. In other cases, composition is performed so that the changed image data represented by the watermark image overlaps at least one of the variable print object of the page data or the variable print object.

In addition, when the cut processing is performed on the printed matter, if the changed image data expressed in the two-dimensional code image fits in the cut portion of the page data, the change expressed in the two-dimensional code image in the cut portion of the page data Synthesize image data. If the image does not fit, the modified image data represented by the two-dimensional code image is not combined with the trimmed portion of the page data. Also, if the modified image data represented by the two-dimensional code image fits in the margin of the page data. Then, the modified image data expressed by the two-dimensional code image is synthesized with the margin portion of the page data. If the image does not fit, the modified image data represented by the two-dimensional code image is not synthesized with the margin of the page data.

  As a result, when the layout change processing result information is combined with the page image and printed, the combined position can be determined in consideration of the post-print processing, so that appropriate changed image data can be added.

[Third embodiment]
A process of changing the layout on the condition that the image of the layout change result information is combined after the layout change process in the layout change process by the in-page object narrowing process in the printing system 101 will be described with reference to the flowchart of FIG. To do.

  In the processing shown in this embodiment, in order to ensure that the visible data generated from the layout change processing information is combined with the designated area in the page data, the print objects other than the layout change result information are preliminarily combined. Determine the position.

  In the inspection device 104 that reads barcode data, when the area on the printed material that can be read is fixed, or when it is desired to print the barcode data at a designated location to make the print appearance easy to see, the barcode data is printed. The position may be fixed.

  In step 1102, the control unit 302 of the variable printing apparatus 102 acquires record information, combines it with a variable template, and creates page data. When the printed product is automatically inspected by the inspection device after printing, the control unit 302 performs composition processing of layout change result information to page data.

  In step 1104, the control unit 302 determines whether the print position is fixed when the layout change processing result is printed as barcode data. When the barcode data printing position is fixed, the control unit 302 arranges the barcode data area at a predetermined position on the page data in step 1105. The object of the barcode data area arranged at this time is added to the table 501 of FIG. 5, and information 0 indicating that the object is not fixed to the movable key 504 is fixed as the attribute value of the object. If the position is not fixed, the control unit 302 arranges the barcode data area as an object that is not fixed at the margin position on the page data in step 1106. As in the fixed case, the bar code area data is added to the table 501 as a movable object for the arranged object, but the movable key 504 records information 1 indicating that the object is movable. The

  After arranging an object indicating the barcode data area in the page data, the control unit 302 causes the layout control unit 303 to execute a thinning process in step 1107. In step 1108, the control unit 302 causes the layout processing unit 303 to perform the thinning process, and then updates the table 501 to generate layout change process result information.

  After the controller 302 generates barcode data from the updated table information in the barcode data 307, in step 1110, the barcode area on the page data arranged in steps 1105 and 1106, and the generated barcode data are displayed. Synthesize. The control unit 302 causes the printing unit 304 to perform printing using the page data obtained by combining the barcode data.

  FIG. 12 is a flowchart illustrating an example of a result of the process of changing and arranging the layout of the object on the page data in the flowchart illustrated in FIG. 5 of the third embodiment. A print object group is arranged in the page data 1201 before the layout change. For example, it is assumed that the barcode data area is fixed to the area indicated by 1204 on the page data 1202. Then, the print object 1205 should be moved and arranged in the direction of the upper side of the page if the process is based on the thinning process algorithm. However, since the bar code data area is fixed in the area 1204, the print object 1205 is moved. Can not do it.

  Similarly, if the barcode data area is arranged and fixed at the position indicated by 1206 of the page data 1203, the print object 1207 moves in the upper side of the page because there is no fixed object that has priority over the position of the movement destination. Arranged. With the layout change process described above, the position where the layout change process result information is displayed on the printed matter is fixed, and the inspection apparatus can read the information from the position determined when reading the layout change process result information from the printed matter. Become.
