[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed matter that assists the human visual inspection by, for example, processing and displaying image data on the printed matter when the human visually inspects the print quality of the printed matter. Of the visual inspection auxiliary device.

[0002]

2. Description of the Related Art Conventionally, in order to inspect the print quality of a printed matter, a method based on human visual inspection and an automatic inspection method based on image processing have been used. For the former method of visual inspection by humans, see, for example, JP-A-63-244.
As disclosed in Japanese Laid-Open Patent Publication No. 173, there is known a labor-saving technique related to a mechanism for handling a printed matter that allows the printed matter itself to be transported and facilitates inspection.

In visual inspection, an afterimage inspection is often carried out in which the same printed matter is continuously observed by turning pages, and it is known that this method is suitable for detecting a slight difference that occurs suddenly. Has been. Among the printing defects, if a defect occurs on the plate, the defect is repeatedly generated at the same position on the printed matter, and therefore it is easier to detect in the afterimage inspection.

In the latter automatic inspection method by image processing, for example, as disclosed in Japanese Examined Patent Publication No. 1-47823, the printed matter is regarded as image data and compared with the reference image data so that There is known a technique of detecting a print defect if there is a difference between the two.

[0005]

SUMMARY OF THE INVENTION The above-mentioned apparatus for assisting human visual inspection by transporting printed matter only assists transportation of printed matter, and the labor-saving effect of visual inspection in printing inspection is low. In the afterimage inspection, it is easy to detect if defects appear repeatedly at the same position, but for example, in the case of a large printed matter in which a plurality of the same images (printing patterns) are present on one printed matter,
The target to be inspected is wide, and it is difficult to perform the afterimage inspection on the entire range.

Even if such a printed matter is taken as an image and inspected, a plurality of images existing in one printed matter are collected one by one, so that the images do not appear continuously and the images are displayed. Visual inspection makes it difficult to notice defects.

Further, in the automatic inspection apparatus by image processing,
It is difficult to distinguish between normal printed matter variations and subtle print defects, and correct printing may be mistaken for defects.
There is a problem that defective printing cannot be detected. Therefore, an automatic inspection apparatus capable of performing 100% erroneous determination with the same determination as a print inspection performed by a human cannot be realized at present, and it is unavoidable to rely on visual inspection.

In view of the above, the present invention reduces the labor of the inspector by processing and displaying the image data on the printed matter in the visually inspected printed matter, and
An object of the present invention is to provide a visual inspection auxiliary device for printed matter, which can eliminate misjudgment and reduce inspection errors.

The judge inputs the judgment data of print quality from the judgment input unit 110 in response to the display on the image display unit 108. The inspection result storage unit 109 stores the determination data input from the determination input unit 110, together with the number (number of sheets) and the column number of the printed matter output from the read control unit 111.
It is stored in a data format such as.

The display image control signal input section 112 is composed of, for example, as shown in FIG. 11, a reproduction switch 408, a pause switch 407, a reverse reproduction switch 406, a fast forward switch 405, and a reverse return switch 404.
By inputting control input information for reconfirmation during inspection by the high-speed page turning operation, the read control unit 111 is given the number of the printed matter P to be read.

As described above, all the image data of the printed matter P can be collected, the image data can be processed and displayed for easy inspection, and the inspection result can be stored. As described above, according to the first embodiment, image data is continuously collected for a printed matter, one printed matter is divided into a plurality of print areas, and the print areas are continuously collected. The image data is stored in order, and then the image data of a plurality of printed materials is continuously read and displayed for each print area, reducing the labor of the inspector (judgment person) and reducing inspection errors. Thus, visual inspection can be facilitated.

Further, according to the second embodiment, image data is continuously collected and stored on a printed matter, and then the stored image data is controlled and read out for each printing area to obtain a plurality of sheets. By displaying the image data obtained by continuously collecting the printed matter, it is possible to reduce the labor of the inspector, reduce inspection errors, and facilitate visual inspection. In this case, although the read control becomes a little complicated, there is a feature that it can be configured with only one data storage unit.

Further, according to the third embodiment, image data is continuously collected for a printed matter, one printed matter is divided into a plurality of print areas, and the print areas are displayed so that the visual observation can be performed. An image can be presented by a plurality of inspectors for inspection and in a form in which a defect can be easily found. As a result, the labor of the inspector can be reduced, inspection errors can be reduced, and visual inspection can be facilitated. In this case, a plurality of inspectors are required, but there is a feature that it can be configured without using a data storage unit.

Further, according to the fourth embodiment, image data is continuously collected for a printed matter and compared with the standard data to mechanically perform a print inspection, and at the same time, one printed matter is printed. Image data that is continuously read for each print area, is combined with the mechanical inspection result and stored, and then the composite image data for multiple prints is continuously created for each print area. By displaying as, it is possible to reduce the labor of the inspector, reduce inspection errors, and facilitate visual inspection. In this case, since the visual inspection is performed while simultaneously knowing the mechanical print inspection result, a more accurate inspection can be realized.
