Printed Target for Cutting Accuracy Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing printing and cutting processes face challenges with accuracy due to potential medium distortion and misalignment during printing, leading to cutting errors that can result in visible white areas along cutting lines, making it difficult to assess the cutting process's accuracy with respect to printed objects on media sheets.
Innovation Solution
The use of a printed target on the media sheet with concentric circles and reference distance measures allows for the assessment of cutting accuracy by comparing the actual cutting line to the intended cutting line, enabling qualitative and quantitative evaluation of cutting errors through visual inspection or tools like magnifying glasses or microscopes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional printing and cutting processes are used without reference targets, then the printing process can be completed, but cutting accuracy deteriorates due to medium distortion and misalignment
Solution Approach 1:
The patent applies preliminary action by printing reference targets on the medium before the cutting process. These targets include geometric shapes with known dimensions and positions that serve as reference markers. By establishing these references in advance, the system can later detect and compensate for any medium distortion or misalignment, thereby maintaining cutting accuracy despite variations in the printing or handling process.
Solution Approach 2:
The patent implements feedback by using the printed reference targets to measure actual medium position and distortion after printing. The detected deviations from the intended reference positions are fed back to adjust the cutting process parameters, enabling real-time compensation for medium variation and ensuring consistent cutting accuracy across different batches.
2Measurement precision
If cutting is performed without reference targets, then the process is simpler, but it becomes difficult to assess cutting accuracy
Solution Approach 1:
The patent introduces reference targets as an intermediary element between the printing and cutting processes. These targets act as measurable mediators that translate physical medium distortion into quantifiable data. By incorporating these intermediary reference markers, the system gains the ability to precisely measure cutting errors while the added complexity remains limited to printing simple geometric patterns.
3Adaptability or versatility
If medium distortion occurs during printing, then printing flexibility is maintained, but cutting line accuracy deteriorates
Solution Approach 1:
The patent applies parameter changes by using reference targets to detect shifts in medium physical parameters (position, shape, orientation) after printing. The system measures actual versus intended reference positions and uses these measurements to dynamically adjust cutting parameters, compensating for medium distortion while preserving printing flexibility.

AI summary
A method is provided. The method includes printing a target (514) on a medium (10) and defining at least one intended cutting line (16) on the medium. The target includes at least one graphical element which defines at least one reference distance measure. The target is centered at the intended cutting line or has a defined distance to the intended cutting line. The accuracy of cutting the medium along the intended cutting line, therefore the cutting error of the actual cutting line (24), can be optically assessed. If making use of the printed target, the assessment of the accuracy of cutting can be qualitative and quantitative.
