Digital Printing Varnishing Unit Configuration via Automated Region Labeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for configuring further processing units in digital printing machines, such as varnishing units, are time-consuming and costly due to manual adjustments and the difficulty in allocating settings to specific regions on printed sheets, especially when multiple sets of parameters are tested simultaneously.
Innovation Solution
A method where a configuration program on the digital printing machine creates and applies different settings for further processing regions on the printed substrate, printing these settings next to the corresponding regions for easy identification and evaluation, allowing for automated testing and efficient allocation of settings.

Engineering Contradiction Analysis
1Productivity
If multiple sets of settings are tested simultaneously on one print sheet, then productivity is improved by reducing the number of copies needed, but the difficulty of detecting and measuring increases because it becomes harder to allocate individual regions to their corresponding settings
Solution Approach 1:
The print sheet is segmented into multiple distinct regions, each associated with a specific set of varnishing unit settings. Each region is clearly demarcated and labeled with its corresponding settings, allowing simultaneous testing of multiple settings on a single sheet while maintaining clear traceability between settings and results.
Solution Approach 2:
A configuration program acts as an intermediary between the operator and the varnishing unit settings. This program automatically generates the test sheet with multiple regions, assigns settings to each region, and provides a systematic method for tracking which settings were applied to which regions, eliminating the manual tracking burden.
2Ease of operation
If settings are adjusted manually by the operator, then ease of operation is maintained, but loss of time increases due to the iterative process of producing copies and evaluating settings
Solution Approach 1:
The configuration program performs preliminary actions by automatically generating test sheets with multiple pre-configured regions, each with different settings. It also prepares the tracking system that links settings to regions before the actual varnishing process begins, eliminating the need for manual setup and iterative copying.
Solution Approach 2:
The system enables self-service operation where the configuration program automatically manages the entire testing process - from generating the test sheet with multiple regions to tracking which settings were applied where. The operator simply initiates the process and the system handles the configuration and evaluation automatically.
3Manufacturing precision
If the varnish image is adapted to the printed image by varying registers, then manufacturing precision is improved, but loss of time increases due to the iterative adjustment and copying process
Solution Approach 1:
The system dynamically adjusts multiple register settings (circumferential, lateral, and diagonal) across different regions of the test sheet. Each region can have different register configurations, allowing comprehensive testing of register alignment options in a single operation rather than through iterative adjustments on separate copies.

AI summary
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.
