Adjusting Page Edge Colors to Reduce Cutting Deviation Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When forming images of multiple pages on a single recording medium without margins between adjacent pages, portions of one page may include images from adjacent pages due to positional deviations during image formation or cutting, making these portions noticeable after cutting.
Innovation Solution
An image forming apparatus that adjusts the position or angle of adjacent pages in print data so that the edge portion colors of adjacent pages satisfy a predetermined condition, ensuring that even if there are positional deviations, the included portions are less noticeable during cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple pages are arranged without margins on a single recording medium, then productivity is improved by reducing the number of sheets, but manufacturing precision deteriorates due to noticeable image portions from positional deviations during cutting
Solution Approach 1:
The patent applies local quality by making the edge portions of adjacent pages have similar colors or patterns. Specifically, the edge portion of each page is designed to match the color characteristics of the adjacent page's edge portion, so that when positional deviations occur during cutting, the mismatch is minimized and less noticeable. This local modification of page edge characteristics resolves the contradiction by maintaining high productivity (no margins) while improving the perceived positioning accuracy.
2Manufacturing precision
If margins are provided between adjacent pages, then manufacturing precision is improved by preventing noticeable image overlap, but productivity deteriorates due to increased paper consumption
Solution Approach 1:
Instead of providing margins across the entire page, the patent applies local quality by modifying only the edge portions of pages. The edge portions are designed with color-matching characteristics that reduce the visibility of positional deviations. This allows the elimination of margins (improving productivity) while maintaining the appearance of precise positioning (maintaining manufacturing precision perception).
Solution Approach 2:
The patent changes the color parameters of the edge portions of pages to match adjacent pages. By adjusting the color characteristics of specific regions (edge portions) rather than the entire page, the invention achieves the effect of reducing noticeable image overlap without requiring margin spaces, thus resolving the contradiction between productivity and manufacturing precision.

AI summary
An image forming apparatus is configured to arrange a plurality of pages, including a first page and a second page adjacent to the first page, in print data, without providing a margin between adjacent pages in the plurality of pages. The image forming apparatus includes a changer configured to change at least one of a position or an angle of the second page, such that a color of a first edge portion region of the first page and a color of a second edge portion region, adjacent to the first edge portion region, of the second page, satisfy a predetermined condition.
