Self-Adaptive Post-Printing Treatment Alignment via Printed Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the printing industry, post-printing treatments face challenges due to mechanical instability, leading to displacement, scaling, or skewing of printed content, which requires tedious manual adjustments to correct errors in positioning.
Innovation Solution
A method and system for self-adaptive adjustment in post-printing treatment that involves printing identifiers on the paper sheet, detecting their locations using a scanning head, and adjusting the treatment mechanisms accordingly to align with actual positions, enabling automatic correction of errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual measurement and manual input are used to amend the editing program in response to skewing, stretch or shrink errors, then the positioning accuracy can be corrected, but the operation becomes very tedious and time-consuming
Solution Approach 1:
The system enables automatic detection and correction of positioning errors through the scanning head that automatically identifies identifiers and the controller that automatically amends the editing program, eliminating the need for manual measurement and input operations while maintaining positioning accuracy
Solution Approach 2:
The patent replaces manual mechanical measurement and input operations with an automated optical-mechanical system consisting of a scanning head that detects identifier positions and a controller that automatically calculates and amends the editing program based on detected deviations
2Productivity
If automated detection and adjustment systems are implemented to correct positioning errors automatically, then the operation time is reduced and productivity is improved, but the device complexity increases
Solution Approach 1:
The patent introduces identifiers as intermediary elements that are printed on the paper sheet and serve as reference markers for the scanning head to detect positioning deviations. These identifiers act as a mediator between the printing process and the detection system, enabling automatic error correction without requiring complex direct measurement mechanisms
Solution Approach 2:
The system uses a copying approach where identifiers are printed on the paper sheet alongside the actual content, creating a duplicate reference system that can be detected by the scanning head. This allows the system to copy the positioning information and use it for automatic correction without requiring complex direct measurement of the actual content positions

AI summary
A method of self-adaption adjustment for post-printing treatment including steps of S1: printing a plurality of identifiers on a paper sheet for positioning actual locations of treatment on the paper sheet; S2: detecting the identifiers on the paper sheet, and locating the actual locations to be treated according to the locations of the identifiers and/or relative locations among the identifiers; and S3: adjusting locations of treatment from a post-printing treatment mechanism to the paper sheet according to the actual locations output in step S2. A system of self-adaption adjustment for post-printing treatment including a printing module, a detection module, a treatment module, a driving module and a post-printing treatment mechanism. The method and system realize the self-adaption adjustment, which effectively solves the problems that an actual value after skewing or stretching or shrinking the actual printing content is inconsistent with a theoretical value of typesetting, thus effectively improving the production efficiency and production quality, which has favorable economic and social benefits. The method and system can be widely applied in various post-printing treatment systems.
