Conventionally, the mainstream method for inspecting printed matter has been offline and relying on one person's visual sense. This stems from the fact that each piece of printed matter has a different pattern, and because the inspection items for printed matter have been thought to involve subtle differences that require relying on human vision.℃・ru . On the other hand, in response to the desire to evaluate the printed matter being printed, attempts have been made to use strobe lighting synchronized with the printing speed and to use mirrors that rotate synchronously at high speed to judge the printed matter as a still image count. It was. However, these methods were not systems that could be called inspection machines in that they relied on human vision for inspection. In addition, attempts have been made to print a color punch at the same time as the pattern on the printed matter and inspect the color batch, thereby allowing the inspection of the printed matter to be performed on behalf of the user. However, with this method, if a printing problem (oil dripping, stains, etc.) occurs in the pattern area, it will be overlooked, and it could not be said that the function of the inspection machine was fully fulfilled.

On the other hand, recently, Japanese Patent Application No. 1051/1983 or Japanese Patent Application No. 1987-
A system has been proposed in which a licensor is used to inspect printed matter in-line, as seen in the "printed matter inspection device" proposed in No. 220515 and the like.

A strip of printing paper (2) is fed from a roll of paper (1) attached to a part of the feeder of the printing machine. ) is printed, and then transported to a dryer and a folding machine (not shown). In order to inspect the printing condition after the front and back sides have been printed in four colors, the printed matter inspection device uses a rotary encoder (5) installed in the printing section to time the sampling, and the image information is processed by the licensor in the detection section (4). It is taken into circuit (6) and judgment work is performed. As a result, if it is determined that the printing condition is abnormal, it becomes possible to take measures such as alarms, markings, and rejects.

Here, the image information input from the detection section (4) plays two roles in the processing circuit (6): reference information and inspection information. The reference information is the image information of the pattern of the printed material at the time when the operator determines that the printing is normal.
The image information is stored in a reference information memory and is used as a reference for inspection. On the other hand, inspection information is information that is input from the detection unit (4) after the reference information is stored in the memory, and is compared (difference, differentiation, etc.) with the reference information to determine a predetermined tolerance range. By determining whether the printed matter is good or bad by determining whether or not it exceeds the limit, in-line inspection of the printed matter becomes possible.

As a result, it is understood that in this system, inspection is impossible before the reference information is input, that is, during the transition from the start of printing to normal printing.

In actual printing, a large amount of defective printed matter is generated during the transition from the start of printing to the normal printing state.In particular, rotary printing machines have a large loss of printing paper, so at what point after printing has started is it possible to print normally? There is a desire to automatically determine whether the transition has been made. It is clear that the printed matter inspection apparatus of the invention is completely ineffective in meeting this demand, and a solution to this problem has been desired.

For this reason, the standard information setting device of the present invention prepares a plurality of proof prints in advance, and prepares a spare proof print that will not be given to the orderer, that is, a proof print that does not have red or other red pattern information written on it. Further, a characteristic of proof printed matter is that it is often printed in units different from those used in printing on an actual printing press. This is due to the difference in size (printing area) between the printing machine for proof printing and the actual printing machine, and the fact that for printed matter such as books and magazines, the destinations for submitting proof printing for advertisements and body text are different.

This process is especially necessary when the proof print differs in some respects from the final print. In other words, due to the nature of the proof print, the ordering party wishes to make a partial correction, but due to deadlines, etc., there are cases where the actual printing material is used without creating a proof print with that part corrected again. . In this case, by setting the inspection standard loosely (increasing the tolerance) for a part of the proof print (for example, changing the color of text, etc.), it is possible to prevent the number of input strokes from being slightly different from the final print. Information can also be inspected to some extent.

For example, we have already mentioned that it is necessary to set loose inspection standards for the parts of the proof print that have been corrected, but since the proof print is strictly speaking a different print from the print that should be inspected, it is necessary to set lenient inspection standards. Compared to testing based on information, it is often better to perform testing using temporary reference information with a rough overall tolerance. For this reason, data representing rough inspection standards may be simultaneously recorded on a floppy disk and delivered to the print inspection apparatus.

Further, there is no problem even if the temporary reference information is coarser than the pixel size in the regular inspection, and in this case, it is sufficient to make a plurality of pixels of the print inspection device correspond to the same data of the temporary reference information.

As described above (according to the standard information setting device for printed matter inspection according to the present invention, it is possible to perform inspection by the printed matter inspection device from the start of printing to normal printing, which was impossible in the past). As a result, it is possible to easily determine the point at which normal printing will occur, reduce the workload of printing press operators such as monitoring duties, stabilize the quality standards of printed matter, and prevent defects that occur at the start of printing. By early detection and feedback of printed matter, the number of defective printed matter can be kept to a minimum, making it possible to reduce the cost of materials such as printing paper and printing ink.
