Edge Printing on Trimmed Paper Cross-Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses struggle to print text and images on the edge of recording paper, especially in production printing, where printed matter is typically trimmed after printing, making it difficult to identify or track printed materials without additional special printing processes.
Innovation Solution
An image processing apparatus and method that includes a data position acquisition unit to acquire print data and the position of the cut line, and a cross-section drawing unit to draw fragments of text and/or images visible on the trimmed cross-section from the cut line to a specific range, allowing for visible printing on the trimmed edge of the paper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If printed matter is trimmed after printing using conventional methods, then the edges are clean and professional, but text and images cannot be printed on the trimmed edge for identification or tracking
Solution Approach 1:
The system performs preliminary action by calculating and marking the cut line position on the printed matter before actual trimming occurs. The edge printing position is determined based on the predetermined distance from the cut line, ensuring that identification text or images are printed at the correct location even before the cut line is physically marked or the trimming is executed.
2Ease of operation
If text and images are printed close to the edge for visibility after trimming, then readability improves, but the content may be cut off by the trimmer
Solution Approach 1:
The system applies local quality by setting different printing positions for different regions of the printed matter. Specifically, identification text or images are printed at a predetermined distance from the cut line position, while other content maintains its original positioning. This localized adjustment ensures that only the necessary identification elements are positioned to be visible after trimming, without affecting the completeness of other content.
3Productivity
If conventional printers are used for production printing, then printing speed and efficiency are high, but special printing processes are required to add identification marks
Solution Approach 1:
The system merges the identification printing function with the conventional printing process. By integrating the cut line position calculation and edge printing position determination into the existing printing workflow, the system enables identification marks to be printed using standard printers without requiring separate special printing processes or additional equipment, thus maintaining high printing efficiency while reducing process complexity.
Data Source
AI summary
Provided is an image processing apparatus that draws a cross-section to be trimmed. The data position acquisition unit acquires the print data and the position of the cut line trimmed after printing with the print data. The cross-section drawing unit draws, for each page of the print data, a fragment text and/or image visible on trimmed cross-section from the position of the cut line acquired by the data position acquisition unit to a specific range. At this time, the cross-section drawing unit may draw the fragment when the print data has equal or greater than a specific number of pages. Further, the cross-section drawing unit may adjust drawing of the fragment according to thickness of recording paper to be printed.
