Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed matter inspecting apparatus, a printed matter inspecting system, a printed matter inspecting method and a storage medium, and more particularly to a technique suitable for use in a system for automatically inspecting printed matter printed by an ink jet type printing apparatus. It is about.

[0002]

2. Description of the Related Art In recent years, addresses, messages, and the like to catalogs, direct mails, and the like have been created using an inkjet printing apparatus.
Printing of logos, marks, illustrations, images, and the like has been widely performed. However, when printing is performed using an inkjet printing apparatus, a printing failure specific to the inkjet printing apparatus may occur.

[0003] For example, "ink dripping" in which ink is continuously ejected from the ink jet nozzle due to a failure of the ink jet nozzle or driver, "ink missing" in which ink is not ejected because the ink jet nozzle is blocked by a solid material, and the like. Is a failure.

[0004] Usually, an ink jet printing apparatus has a recording head having a plurality of nozzles, and there is an inherent problem that if even one of the plurality of ink jet nozzles fails, a printing failure occurs.

[0005]

In an ink-jet printing apparatus, since the above-described printing failure may occur, generally, a printed portion is visually inspected to determine whether there is any printing failure. Has been determined.

However, when variable information is printed by an ink-jet printing apparatus that prints at high speed, it is impossible to visually inspect all of the printing results. Inspection is underway. For example, a visual inspection is performed by sampling such that one printed material is inspected for 100 printed materials.

[0007] When a defect occurs, the printed matter printed before and after the defect is intensively inspected to sort out and remove the defective print. Performing such a task at all times is a heavy burden on the human and is a task that is extremely tired. In addition, in the case of visual inspection, there is a problem that the risk of defective products being mixed into products due to oversight is inevitable.

In order to solve such a problem, there has been known a method of detecting a print result by an image sensor and comparing the detected print image with a reference image to check the print result.

The inspection method based on the image comparison is a very effective method when the contents to be printed are the same. However, the content printed by the ink jet printing apparatus is mostly variable information that varies depending on each printed matter, such as personal information such as a destination and a name, billing information, etc., and the reference image differs depending on the individual printed matter. There are many. For this reason, the method of comparing and determining a print image and a reference image cannot be often adopted in the case of an ink jet printing apparatus.

Further, as a result of the recent increase in the speed of the printing apparatus, it is practically difficult to inspect all the printing results. For this reason, when performing the performance inspection of the print head, a predetermined pattern is printed at a predetermined timing, and if there is no problem in the result of printing the predetermined pattern, the actual printing is performed without any problem. It was an indirect test that was judged to have been performed.

That is, in most of the conventional high-speed ink-jet printing apparatuses, it is almost impossible to directly inspect the actual printing result, and it is detected that incorrect printing has been performed on important documents and personal data. There was always the danger of overlooking it if it couldn't.

Then, the images read by the three OCR cameras 12a to 12c and the barcode reader 13 are received and coded.

Next, the execution procedure of the printed matter inspection method of the present invention will be described with reference to the flowchart of FIG. When the inspection process is started, a layout is defined in a first step S31. As described above, this layout definition adds layout information based on variable information such as customer details and address data, and font files such as characters and designs. Next, the process proceeds to step S32 in which data is arranged in an interface suitable for the printing machine 7 (data merge) to generate print data.

Next, the process proceeds to step S33, where a verification field is defined. The verification field refers to a field for which the validity of the print data is checked, and in the present embodiment, the four fields 11a shown in FIG.
１１11d. Note that this verification field definition may be independently performed in addition to the case where the layout field is defined as in the present embodiment.

Next, the process proceeds to step S34, where the verification device 2
Is performed, and verification setting data is transmitted to the verification device 2. In addition, data corresponding to the field for which the verification has been set is extracted from the input data D1, the order (record number) is given, and the verification data D3 is created.

Next, the process proceeds to step S35, where the imaging state of the image recognition device 7 is adjusted based on the verification data D3 so as to match the imaging position defined in step S33. Thereby, the three OCR cameras 12a to 12
The imaging positions of the barcode reader 12c and the barcode reader 13 are set so as to correspond to the four fields 11a to 11d.

Next, in step S36, a process of recognizing the print result by the image recognition device 7 is performed. That is, as described above, the three OCR cameras 12a to 12c
Are used to image the first to third verification fields 11a to 11c to generate image data, and to display the customer barcode on the barcode reader 13
A process for optically reading and encoding the data is performed.

Next, in step S37, the quality of the print quality is determined. If the result of this determination is that the print quality is good, the flow advances to step S38 to execute processing for normal printing. If the print quality is not good, step S3
Proceeding to 9, the processing at the time of printing failure is executed.

When the processing in step S38 or the processing in step S39 is completed, the process proceeds to step S40, in which it is determined whether or not the print quality inspection processing is to be completed. Repeated processing.

Next, an example of the normal printing process performed in step S38 will be described with reference to the flowchart of FIG. First, when the process starts, in step S41, a patrol lamp, which is one of the inspection result execution devices 4, is operated normally. This is, for example, if it is determined that the light is turned off when the print quality is normal and turned on when the print quality is poor,
It should be turned off. When the print quality is normal, the light is turned on, and when the print quality is poor, the light is turned on when it is determined to blink.

Next, the process proceeds to step S42, in which the flap is set in a state of receiving a normally printed product. This allows
All the printed materials 11 are conveyed to the next process without being excluded.

Then, the process proceeds to a step S43, wherein the printed matter 11
Is operated so as to perform an operation based on the normal print detection signal. In the next step S44, control is performed so that a binder for sandwiching another printed material into the printed material 11 operates normally.

Next, in step S45, control is performed so that various facilities including the paper transporting device 9 operate normally. When these processes are sequentially performed, the process returns to the main routine.

Next, referring to FIG.
An example of the processing at the time of a printing failure performed in No. 9 will be described. First, when the process starts, in step S51,
A patrol lamp, which is one of the inspection result execution devices 4, is operated when an abnormality occurs. This means that, for example, if the print quality is normal, the light is turned off, and if the print quality is poor, the light is turned on if it is determined that the light is turned on. If the print quality is normal, the light is turned on. If the print quality is not good, the light is turned on and off.

Next, the process proceeds to step S52, in which a flap, which is a device for removing defective prints, is operated to set a defective print removal state. As a result, all the printed materials 11 in which the printing failure has occurred are excluded.

Then, the process proceeds to a step S53, wherein the printed matter 11
The operation of the stacker, which is a device for classifying the print error, based on the print defect detection signal is performed. Further, the next step S5
In 4, the control is performed such that a binder for sandwiching another printed material in the printed material 11 is operated when a printing failure occurs.
These control contents can be arbitrarily set, for example,
Control is performed so that the printed matter 11 printed separately is not sandwiched between the printed matter 11 having poor printing.

Next, in step S55, various facilities including the paper transport device 9 are controlled so as to perform an operation when a printing failure occurs. The contents of the processing can be arbitrarily set, for example, by stopping the sheet transport equipment, operating an alarm, or the like.

Next, the process proceeds to step S56, in which print data and verification data relating to the printed matter 11 in which the printing failure has occurred are created. The timing for executing printing and inspection based on the created print data and verification data may be set arbitrarily. When these processes are sequentially performed, the process returns to the main routine.

According to the present invention, the print quality is inspected as described above. Therefore, even when the variable information is printed by an ink jet printing apparatus which prints the information at high speed, the print quality is inspected for all the print results. be able to.

As a result, when a printing failure occurs, it is possible to select and remove the printing failure from the printed matter, and it is possible to completely guarantee the printing data without imposing a human burden. In the case of visual inspection, there is a risk that a defective product may be mixed into a product due to oversight, but this can be reliably eliminated.

Furthermore, since the print inspection is executed based on the order, even if the content to be printed is variable information that differs depending on each printed matter, it can be performed well. This greatly reduces the likelihood of incorrect printing of important documents and personal data,
It is possible to completely guarantee the print data.
