Embodiment Construction

[0023] The field of application of a preferred embodiment variant of the method according to the invention is inkjet printers 7 . exist figure 1 An example of the basic structure for such a machine / sheet inkjet printing machine 7 is shown in , comprising the feeder 1 for feeding the printing substrate 2 into the printing unit 4 up to the receiver 3, in the printing unit 4 Printing is performed on the printing substrate 2 by the printing head 5 . This is a sheet inkjet printing press 7 , which is controlled by a control computer 6 .

[0024] When (or after) such an inkjet sheet printing machine 7 is assembled, a complete functional test at this point (including eliminating any errors found by means of calibrating the newly constructed sheet inkjet printing press 7) is worth looking forward to. This application scenario is in the preferred implementation variant in figure 2 in public. Because this cannot be carried out by (as in an offset printing press) real proof printin...

Abstract

The invention relates to a method for automatically calibrating a printing press (7) with an image detection system by means of a computer (6), comprising the steps of introducing at least one printing sample substrate (9) with defined deviations into the In the printing machine (7); the digital image of the printing sample base (9) is generated by the image detection system; the configuration parameters (17) for the printing machine (7) are calculated by the computer (6) Actual compensation values ​​(15) including defined deviations for optimizing print quality; compare the created actual compensation values ​​(15) with the known defined deviations of the printing sample substrate (9) Comparing the nominal compensation value (18) of the above-mentioned printing machine (6) by computer (6) to check the functional capability of the printing press (7) and / or by means of the computer (6) to calibrate by means of the analyzed comparison The printing press (7).

Description

technical field [0001] The invention relates to a method for automatic calibration of a printing press with an image detection system by means of a computer. Background technique [0002] The invention belongs to the technical field of test automation. [0003] In practice, conventional offset printing presses are checked for their complete functional capability after the individual components have been produced after their assembly. This usually takes place by carrying out a test print which covers the widest possible range of aspects of the functionality of the printing press concerned. As a result, errors detected in the printing press concerned can also be eliminated during production at the manufacturer. The printing press can then be released (freigegeben) and delivered to the respective customer. [0004] A similar process is currently not possible in inkjet printers. The reason for this is that between this functional test (also referred to as proof printing) and...
