Mark Arrangement for Post-Cut Image Sorting in MFPs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing and forming technologies require manual visual inspection to sort multiple types of printed images after cutting, which is cumbersome due to the need to distinguish between images with different print counts on stacked sheets.
Innovation Solution
An image processing apparatus, such as an MFP, is equipped with a CPU, ROM, RAM, image reading, and forming units, which performs imposition patterns on a sheet by allocating images in segmented areas and arranging marks at scheduled cutting positions, allowing for easy identification and sorting of images post-cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple types of images are printed on stacked sheets, then productivity is improved by printing multiple images per sheet, but manual visual inspection becomes necessary to sort images with different print counts, increasing operation complexity
Solution Approach 1:
The patent applies preliminary action by pre-printing identification marks on the sheets during the printing process. These marks are placed in advance to enable automatic or easy identification of image types after printing, eliminating the need for manual visual inspection during sorting operations.
Solution Approach 2:
The patent uses identification marks as an intermediary element between the printed images and the sorting operation. These marks serve as a mediator that provides visual or detectable information about image types, allowing for automated or simplified sorting without requiring direct visual inspection of the images themselves.
2Difficulty of detecting and measuring
If marks are printed on the sheet surface, then image identification is enabled, but the marks may be visible on the final printed output affecting image quality
Solution Approach 1:
The patent applies local quality by placing identification marks in specific locations on the sheet (such as margins or corners) that are separate from the main image areas. This ensures that the marks are visible for identification purposes while maintaining the quality and appearance of the printed images in their designated areas.
Solution Approach 2:
The patent segments the sheet into distinct areas: one for the printed images and another for the identification marks. This segmentation allows the marks to be printed on the sheet without interfering with the image printing process, as they are placed in separate zones that do not overlap with the image areas.

AI summary
An MFP (Multifunction Peripheral) (100) is an image processing apparatus used for a printing method. In the printing method, plural kinds of images (IMa, IMb, IMc, IMd) are printed on paper. The paper is trimmed after printing. Thereby, each of plural kinds of images (IMa, IMb, IMc, IMd) can be obtained. The MFP 100 includes a mark attaching unit that arranges marks (MKa, MKb, MKc, MKd) corresponding to each of a plurality of kinds of images at scheduled cutting positions (LN1, LN2). As a result, it is possible to easily sort the sheets after cutting.
