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 7 is shown in , comprising the feeder 1 up to the receiver 3 for feeding the printing substrate 2 into the printing unit 4 in which the substrate is printed by the printing head 5 Substrate 2 is printed. 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 printing, so this occurs as follows: its mode is that t...

Abstract

A method for the automated calibration of a printing machine with an image capture system by using a computer, includes putting at least one printed sample substrate with defined deviations into the printing machine, generating a digital image of the printed sample substrate by using the image capture system, calculating current compensation values including defined deviations for configuration parameters of the printing machine relating to optimizing the printing quality by using the computer, and comparing the current compensation values created with target compensation values known from thedefined deviations of the printed sample substrate. Serviceability of the printing machine is checked by evaluating the comparison by the computer and/or calibrating the printing machine by using theevaluated comparison by the computer.

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...
