Print Direction Mark for Post-Processing Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the Print On Demand market, operators face difficulties in accurately setting print products to post-processing apparatuses due to limited information from printed register marks, leading to reduced work efficiency as the operator may not recognize the correct orientation of each print product relative to the finisher, often requiring communication with the job creator.
Innovation Solution
A document processing system that includes a printing apparatus capable of printing a mark indicating the sheet-feeding direction, allowing operators to accurately set print products to the post-processing apparatus by predicting and displaying the sheet-feeding direction, thereby eliminating orientation errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If register marks are printed on all pages for cutting processing, then cutting accuracy is improved, but mark registration deviation occurs and printed marks remain on the print product
Solution Approach 1:
The patent extracts the register mark information from all pages and concentrates it only on the leading page. The setting direction mark is printed exclusively on the leading page of the print product, eliminating redundant marks on subsequent pages while maintaining cutting accuracy and preventing mark registration deviation.
Solution Approach 2:
The setting direction mark is printed in advance on the leading page during the printing process. This preliminary marking provides the operator with orientation information before the print product reaches the post-processing apparatus, enabling correct setting without requiring marks on all pages.
2Device complexity
If only printed register marks are used for orientation information, then the system remains simple, but the operator cannot accurately identify the correct orientation of each print product
Solution Approach 1:
The patent applies local quality by placing a specific setting direction mark at a predetermined position on the leading page. This localized mark provides concentrated orientation information exactly where the operator needs it, improving information availability without adding system complexity.
3Adaptability or versatility
If the job creator and finisher operator are different people, then task specialization is improved, but communication overhead increases and work efficiency decreases
Solution Approach 1:
The patent enables the finisher operator to independently determine the correct setting direction by viewing the setting direction mark on the print product. The mark provides self-contained orientation information that eliminates the need for communication with the job creator, allowing task specialization to be maintained without communication overhead.

AI summary
A document processing system includes a printing apparatus configured to perform printing and a post-processing apparatus configured to execute post-processing on a print product. The document processing system includes a setting unit configured to set a sheet-feeding direction of the print product to be fed to the post-processing apparatus, and a print control unit configured to control the printing apparatus to print on the print product a mark indicating the sheet-feeding direction set by the setting unit.
