Abstract

A method for configuring the further processing of printing substrates in a digital printing machine includes modifying settings for configuring the further processing while the machine is in operation. The settings of the further processing are created by using a configuration program running on a control unit of the digital printing machine. The modified settings have an effect on at least one region to be further processed on the printing substrate and the settings are printed onto the printing substrate so as to be allocated to a corresponding region to be further processed.

First claim

The invention claimed is:

1. A method for configuring a further processing of printed printing substrates in a further processing unit of a digital printing machine, the method comprising the following steps:
creating different settings to configure the further processing of the printed printing substrates by the further processing unit while the machine is in operation by using a configuration program running on a control unit of the digital printing machine;
printing test contents in different test regions on the printing substrate by using the digital printing machine controlled by the configuration program, while also printing the different settings on the printing substrate so as to be allocated to correspond to the test regions with the test contents on the printing substrate;
assigning a single setting to every test region with the test contents to configure the further processing of a printed printing substrate by the further processing unit;
printing the different settings in empty regions on the printing substrate being free to be used; and
using the different settings to affect the test regions with the test contents of the printed printing substrate to be further processed by the further processing unit by applying the assigned setting for further processing for every test region.

2. The method according to claim 1 , which further comprises using an operator to compile the different settings by using the configuration program.

3. The method according to claim 1 , which further comprises using the configuration program formed as an unvarying calibration program to compile the different settings.

4. The method according to claim 1 , which further comprises implementing the further processing of the printing substrate as an application of varnish by a varnishing unit wherein the settings refer to a configuration of the varnishing unit.

5. The method according to claim 4 , wherein the different settings include process parameters.

6. The method according to claim 5 , wherein the process parameters are selected from the group consisting of a name of the varnish, a batch number of the varnish, a screen roller number, target register settings and target dryer settings for the varnishing unit.

7. The method according to claim 1 , which further comprises visibly applying the different settings next to the at least one region to be further processed.

8. The method according to claim 7 , which further comprises applying the different settings in such a way as to be machine-readable and evaluated in an automated way.

9. The method according to claim 7 , which further comprises applying the different settings as a QR or bar code.

10. The method according to claim 1 , which further comprises simplifying the printed image in register-relevant areas to simplify a visualization of the further processing in comparison with an actual printed image.
