Description

The present invention relates to an image inspection device and an image inspection program for inspecting an abnormality in a printed matter by comparing an image with an image obtained by reading a printed image.

The paper printed by the image forming apparatus may have abnormalities such as stains and scratches on the image for various reasons.
In order to detect an abnormality, there is a technique for detecting an abnormality by scanning the paper immediately after printing with a scanner or the like. In this technique, an abnormality is detected by first printing and scanning the first image, registering it as a correct image, and then comparing it with the scan result of the printed image.

On the other hand, in recent years, there is a technique called variable printing that generates a different image for each record according to the value of the record recorded in the database. In recent variable printing formats such as PPML and PDF / VT, information on whether or not they can be reused is embedded in each object. The reused object temporarily stores the data after the rasterization process (RIP), and then reuses the RIP-completed data each time the reused object is drawn, so that it can be compared with the conventional print image format. It is possible to improve the processing time. Even in such variable printing, it is required to inspect the printed matter for abnormalities.
However, in variable printing, since a part of the image is different for each paper, there is a problem that the output image of the first copy cannot be compared with the scanned correct image, and the image abnormality detection process cannot be performed.

On the other hand, in Patent Document 1, a reused object in variable printing is detected, an image after RIP is recorded as a correct image, and an inspection process is performed by comparing with the RIP result of the reused object used thereafter.
Further, in Patent Document 2, the correct image is generated from the information of the reused (fixed) object and the variable object, but since the reused object is always treated as a fixed object arranged in the same place, the arrangement of the reused object is performed. If is different for each page, it is treated as a variable object.

<Embodiment 1>
Variable printing performed by the image forming apparatus 10 will be described with reference to FIG.
FIG. 3 shows an example of the variable printed matter used in the present invention. Paper P has been printed, and the image on each page is composed of a reusable object area 201 and a variable unique object area 202. A reusable object is an object that is repeatedly used, and a variable unique object is an object whose contents are variable at a unique arrangement position.

FIG. 4 shows an example of output results arranged in page order in the example of FIG. At the location corresponding to the reused object in FIG. 3, any one of the reused object areas 201A, 201B, and 201C composed of three types of images "A", "B", and "C" is arranged. As the variable unique object in FIG. 3, the variable unique object area 202 of the image, which is used only once in the previous page, is applied.

FIG. 5 shows the types of correct image examples in the print example shown in FIG. Since the number of combinations of the arrangement information of the reused object and the variable unique object in FIG. 4 is three, the correct image is generated according to the number.
The variable eigen object area 212, which is used only once in the job in FIG. 4, has only the attribute information which is a variable eigen object in the correct image, and is blank as the image information. The reusable object areas 211A, 211B, and 211C that are repeatedly used have image information and attribute information, respectively.
At the time of inspection processing, the reused object areas 201A, 201B, 201C print the correct image data, compare the scanned image with the reused object areas 211A, 211B, 211C of the correct answer image, and determine whether there is a difference.
In the variable unique object area, an inspection process different from that in the reuse object area is performed. Examples of different processing referred to here include processing such as comparing with a RIP-completed image instead of a scanned correct image, comparing with a record value included in the database used when generating a variable print job, and not performing inspection processing. Can be mentioned.

FIG. 6 shows a table associated with the correct image corresponding to each page. The table is recorded in the image forming apparatus, and the inspection process is performed by comparing with the corresponding correct image at the time of image output of each page.
The correct image number is different for each page, and the content of the reused object and the content of the variable unique object are determined for each page.

<Embodiment 2>
FIG. 7 shows an example in which the reused object area 303, which is commonly arranged on all pages, is arranged in addition to the reused object area 301 and the variable unique object area 302 in FIG. The reused object area 301 is a variable area.
FIG. 8 shows an example of output results arranged in page order in the example of FIG. As the reused object area 301, the reused object areas 301A, 301B, and 301C are indicated by variable contents.
FIG. 9 shows an example of the correct answer image in the example of FIG. In this embodiment, in addition to the first embodiment, the reused object area 313 that is commonly arranged on all pages is arranged at the bottom of the page. Therefore, in the arrangement information of this embodiment, the number of correct images is set. As in the first embodiment, three types of correct image are generated without any influence, and the reused object areas 311A, 311B, 311C and the variable unique object area 312 are arranged.

<Embodiment 3>
FIG. 10 shows an example of a job in which a plurality of variable reuse objects are arranged. In addition to the three types of variable reuse object areas 401A, 401B, and 401C shown in Embodiments 1 and 2 at the top of the page, two types of "A" and "I" at the bottom of the page. The variable reuse object areas 404A and 404B of the above are arranged, and in addition, the variable unique object area 402 and the reuse object area 403 are arranged. The reused object area 403 is an area commonly used for each page.

FIG. 11 shows an example of the correct answer image in the example of FIG. Correct images are generated for the number of combinations of two types of variable reuse objects. In FIG. 10, the number of possible correct answer images is 3x2 = 6 types for a job of all 12 pages, but since there is no combination of "C" and "I" in FIG. 10, 5 types excluding the same combination. The combination is generated as a correct image. That is, in the correct image, the variable reuse object area 411A, 411B, 411C, the variable fixed object area 412, the reuse object area 413, and the variable reuse object area 414A, 414B are arranged.
FIG. 12 shows a table in which the output image of each page and the correct answer image in this embodiment are associated with each other. There are correct images according to the combination of the number of variable reuse object areas 411A, 411B, 411C and the number of variable reuse object areas 414A, 414B.

<Example 4>
FIG. 13 shows an example of variable printing assuming double-sided printing. Variable printing is often used for direct mail, in which case an address is printed on the front side and an individual advertisement is printed on the back side for each individual. In other words, the layout changes drastically for each page, such as the address for odd-numbered pages and the advertisement for even-numbered pages.
On each page, the variable unique object area 501 and the reused object area 502 are arranged on the odd-numbered pages, and the variable reuse object areas 503A, 503B, 503C, the variable unique object area 504, the reused object area 505, and the variable reuse on the even-numbered pages. The used object areas 506A and 506B are arranged.

FIG. 14 shows an example of the correct answer image in the example of FIG. There is only one type of correct image of the address page (odd page in FIG. 13) because the arrangement condition of the reused object does not change. That is, the variable unique object area 511 and the reused object area 512 are arranged. On the other hand, since the arrangement conditions of the reused objects vary from page to page in the advertisement page (even pages in FIG. 13), there are four types (the number of patterns of combinations of objects in the even pages in FIG. 13) according to the same concept as in the third embodiment. ) Correct image is generated. Including the number of combinations described above, the number of correct images in this embodiment is 5 types (1 + 4). That is, the variable reuse object area 513A, 513B, 513C, the variable unique object area 514, the reuse object area 515, and the variable reuse object area 516A, 516B are arranged.

<Example 5>
FIG. 15 shows an example of a correct image at the time of imposition output. In variable printing, the final output result is often a relatively small size paper such as direct mail or advertisement, and at that time, it is conceivable that the paper is impositioned on a large paper and then cut at the end. In this embodiment, correct images are generated for the number of imposition patterns at that time. More specifically, in the image before imposition, two types of variable reuse objects (“A or B or C” and “A or i”) are arranged. The maximum number of combinations that can be considered here is six, and in the present embodiment, four surfaces are provided for one page, so that a maximum of 24 (= 6x4) types of combinations can be considered. Only the combination pattern that is actually printed is extracted from it, and the correct image is generated. On each page, reused object areas 601A, 601B, 601C, variable unique object areas 602, and reused object areas 603A, 603B are arranged.

<Example 6>
FIG. 16 shows an example in which a reuse object and a variable unique object are superimposed.
In this embodiment, three types of reused object areas 701A, 701B, and 701C of "A", "B", and "C" are arranged on the entire surface of each page. A blank object area 702 surrounded by a dashed line superimposed on it indicates a variable eigen object. A part of the reused object is arranged under the broken line area, but the inspection process is performed in the same area as a variable unique object area.

FIG. 17 shows the flow of processing of this embodiment. The following processing is executed under the control of the image inspection control unit.
When the process is started, the correct image input data for each page is generated (step s1).
In the above step, the layout data of all pages is read, and the arrangement information of the reused object and the variable unique object is extracted. This layout data may be read on the layout generation application software for variable printing, or immediately before the variable print format (PPML, PDF / VT, etc.) generated on the application is RIPed by the printing device (controller). It may be the timing of.

A page-based layout pattern is calculated based on these layout information, and correct image data is generated for the number of the layout patterns. More specifically, when a plurality of images are arranged as reuse objects for the same object area on each page, correct image data is generated for the number of the arranged images. When there are a plurality of the regions, correct images are generated for the number of combinations. On the other hand, if variable (unique) objects are placed in the same object area on each page, the number of correct images will not be affected.

After that, variable printing data is generated and associated with the corresponding correct image input data (step s2). That is, in this step, variable print data generation processing (RIP) is performed for each page, and the image is associated with the correct image.

In the generation of variable print data, a layout is specified according to a user's print instruction, and a record is taken out from a customer database or the like and applied to a layout frame in order to assign an image to each of the specified layouts. The image is then mapped to the designated field in the layout to generate variable print data. Then, this process is repeated until the composition of one page is completed.

When the composition of one page is completed, the identification information for identifying the printed matter and the file name of the image mapped to each field are bar-coded and added to the variable print data so as to be combined with the page. Then, this process is repeated until the customer database or the like is completed.
Characters and images registered as variable objects are inserted in the variable area, characters registered as reused objects are inserted in the fixed character area, and images registered as reused objects are inserted in the fixed image area. Is inserted, and the other area becomes a margin area.

Next, only the correct image is printed out, and the result of scanning the result is confirmed (step s3). Next, the output of the correct answer image is repeated until it can be determined by the user's eyes that there is no problem (step s4).
If the user determines that there is no problem with the printed image, it is registered as a correct image (step s5).
The registration of the correct answer image is not limited to a specific method, and may be, for example, an image that has already been used in printing and has no abnormality in the inspection process.
A preview of the scanned image may be displayed when the correct image is created, a variable area may be manually set on the display screen, and the inspection process may not be performed in the variable area.

After the above processing is completed, the output of variable printing is officially started (step s6). After each page is output, the image is scanned and compared with the previously associated correct image (step s7).
As a result of the comparison, it is determined whether there is a problem in the output image (step s8). Whether or not there is a problem with the output image can be determined by an appropriate determination method, and the present invention is not limited to a specific method. For example, the difference can be detected by comparing the scanned image with the correct image, and the presence or absence of a defect on the paper can be determined based on the detection result of the difference. Further, instead of determining all the locations where the difference is detected as defects, it is also possible to determine the locations having differences exceeding the threshold value set by the user as defects.

If there is no problem with the output image (step s8, No), it is determined whether all the images have been output (step s9), and if all the images have not been output (step s9, No), the process proceeds to step s6 and the next step is performed. Print the page. When an abnormality is detected (step s8, Yes), the process proceeds to step s6, the page is re-output, and the process is repeated until normal output is performed.
These processes are repeated until all pages are output, and when all pages are output (steps 9, Yes), all the processes are completed.

In the present embodiment, the above variable area can be automatically set, and the inspection accuracy can be improved by comparing the variable object that is repeatedly used with the scanned image printed out.
Even if the same recycled object is used for variable printing, the adhesion characteristics of toner and ink will change depending on the position of the paper to be printed, and there will be a slight difference depending on how the scanner light hits when creating the correct image. .. In the present embodiment, the first printed result is visually observed, and the image judged by the user to have no quality problem is stored as a correct image and compared. Therefore, it is possible to detect an abnormality during printing.

Although the present invention has been described above based on the above-described embodiment, the scope of the present invention is not limited to the contents of the above-mentioned description, and the present invention is not limited to the above-described embodiment as long as it does not deviate from the scope of the present invention. Appropriate changes are possible.
