Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting printing forms on carriers, especially those made of polymer materials, face challenges in achieving dimensional stability and correct positioning, leading to distortions and inefficiencies in the printing process due to warping and concentricity errors.
Innovation Solution
An assembly device with a holder and pressing device that applies corrective forces using a roller arrangement, aligned transversely to the pressing axis, to compensate for offset and concentricity errors, coupled with a sensor system to ensure precise alignment and adhesion of the printing form to the carrier, utilizing a drive device and control system for controlled movement and force regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If polymer printing forms are used to reduce costs and improve structuring capability, then manufacturing cost and design flexibility are improved, but dimensional stability deteriorates causing warping and positioning errors
Solution Approach 1:
The device applies corrective forces during the mounting process itself, before the printing process begins. The pressing device with corrective force generation compensates for warping and concentricity errors in real-time during application, ensuring the printing form achieves the necessary dimensional stability just before use.
Solution Approach 2:
The system dynamically adjusts pressing parameters including corrective force magnitude and pressing movement characteristics to compensate for dimensional deviations. The control device modifies these parameters based on sensor feedback to maintain optimal adhesion while correcting warping and positioning errors.
2Device complexity
If conventional pressing methods are used, then the mounting process is simple, but positioning accuracy and concentricity deteriorate due to offset and concentricity errors
Solution Approach 1:
The device incorporates sensor devices that detect the actual position and concentricity of the printing form during mounting. This feedback is processed by the control device, which adjusts the corrective force and pressing movement in real-time to eliminate offset and concentricity errors, achieving high positioning accuracy.
Solution Approach 2:
The system replaces conventional simple mechanical pressing with an automated system that integrates sensors, control algorithms, and corrective force generation. This substitution enables precise detection and compensation of positioning errors while maintaining operational simplicity through automation.
3Ease of operation
If adhesive mounting is used to secure printing forms, then ease of application is improved, but adhesion quality and dimensional stability deteriorate due to warping during the process
Solution Approach 1:
The device applies corrective forces during the mounting process itself, before the printing process begins. The pressing device with corrective force generation compensates for warping and concentricity errors in real-time during application, ensuring the printing form achieves the necessary dimensional stability just before use.
Solution Approach 2:
The system dynamically adjusts pressing parameters including corrective force magnitude and pressing movement characteristics to compensate for dimensional deviations. The control device modifies these parameters based on sensor feedback to maintain optimal adhesion while correcting warping and positioning errors.

Function Achieved in This Case
Enables quick and high-quality mounting of printing forms with minimal distortion, ensuring a concentric and correct position on the carrier, thereby improving the quality and accuracy of the printed image by compensating for warping and concentricity issues during the printing process.
Implementation Method 1
a pressing device (9) designed as a roller or roller arrangement for transmitting a compressive force to the printing forme carrier (4)
Implementation Method 2
a correction means for introducing a corrective force whose direction of force deviates from a force direction of the compressive force on the printing forme carrier (4) and the printing forme (1) to be applied thereto in order to compensate for an offset error of the printing forme (1) along the pressing axis and/or a concentricity error of a cylindrically designed printing forme carrier (4)

AI summary
The device (6) has a retainer (7) for retaining a printing form carrier (4), and a pressing device (9) i.e. plate roll and rotatable roll, inserted into the retainer and performing a pressing movement transverse to pressing axles (24). The retainer, the pressing device, a coupling unit (10) and a positioning device (19) introduce correction force that is applied on a printing form (1) and the carrier to compensate offset error of the printing form and concentricity error of the carrier, where force direction of the correction force deviates a force direction of the pressing force. An independent claim is also included for a method for applying a printing form on a printing form carrier.
