Image Processing Apparatus Selective Reprinting Error Pages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple pages are imposed on a single sheet and printed, printing errors such as stains can occur, leading to unnecessary reprinting of error-free pages and increased resource waste, as well as a large number of separate sheets being required for reprinting error-containing pages.
Innovation Solution
An image processing apparatus that identifies and reprints only the pages with printing errors on a single sheet, along with related pages, using a processor to impose and reprint the group of pages as a target, thereby reducing waste and the number of sheets needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all pages are reprinted when a printing error occurs, then the printing error is corrected, but error-free pages are also reprinted causing resource waste
Solution Approach 1:
The patent segments the reprinting process by identifying and isolating only the pages containing printing errors. The image processing apparatus divides the set of pages into error-containing pages and error-free pages, then reprints only the error-containing pages on a new sheet, thereby avoiding unnecessary reprinting of error-free pages and reducing resource waste.
Solution Approach 2:
The patent applies local quality by treating error-containing pages differently from error-free pages. Instead of uniformly reprinting all pages, the system identifies the specific location (pages) with printing errors and applies the reprinting action only to those local areas, preserving error-free pages and optimizing resource usage.
2Reliability
If each page with printing errors is reprinted on a separate sheet, then printing errors are corrected, but the number of sheets required increases
Solution Approach 1:
The patent merges multiple error-containing pages onto a single sheet for reprinting. The image processing apparatus collects pages that contain printing errors and combines them on one or fewer sheets, rather than printing each error-containing page on a separate sheet. This reduces the total number of sheets required while still correcting all printing errors.
3Loss of energy
If multiple pages are imposed on a single sheet, then resource usage is optimized, but printing errors can occur affecting multiple pages
Solution Approach 1:
The patent extracts and isolates the pages containing printing errors from the multi-page imposition. After detecting printing errors on a sheet with multiple imposed pages, the system extracts only the error-containing pages for reprinting, separating them from the error-free pages that were originally imposed on the same sheet. This maintains the efficiency of multi-page imposition while addressing the reliability issue.

AI summary
An image processing apparatus includes a processor configured to impose a group of pages on a single sheet as a target for reprinting and perform reprinting, the group of pages being referred to as printing-error pages, each of the pages having been printed with a printing error that occurred while multiple pages imposed on one or more sheets were printed.
