Cutting Position Control for Image Block Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses fail to consistently achieve desired cutting positions on a continuous printing sheet regardless of the printing order, leading to inconsistent segmentation when the total number of image blocks is not a multiple of the designated number per segment.
Innovation Solution
An image forming system that includes a printing setting unit to designate the printing order and the number of image blocks per segment, with a control unit determining cutting positions based on this information to ensure consistent segmentation independent of the printing order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image blocks are printed in normal order on a continuous sheet, then the first segment contains the first N blocks, but when printed in reverse order, the cutting position becomes inconsistent
Solution Approach 1:
The system performs preliminary calculation of cutting positions based on the printing order (normal or reverse) before actual printing. The control unit determines where to cut the continuous sheet in advance, ensuring that regardless of whether blocks are printed in normal or reverse order, the segments are correctly positioned after cutting.
Solution Approach 2:
The cutting position determination is made dynamic based on the printing order selection. When normal order printing is selected, cutting positions are calculated one way; when reverse order printing is selected, cutting positions are recalculated accordingly. This dynamic adjustment ensures consistent segmentation results regardless of printing direction.
2Adaptability or versatility
If the total number of image blocks is not a multiple of blocks per segment, then cutting positions differ between normal and reverse printing orders
Solution Approach 1:
The control unit performs preliminary determination of cutting positions that account for the total number of blocks and blocks per segment configuration. This preliminary calculation ensures that segments are properly composed regardless of whether the total block count is a multiple of blocks per segment, and regardless of printing order.
Solution Approach 2:
The system uses feedback from the printing order selection and block count configuration to adjust cutting position calculations. The control unit receives information about the printing order and total block count, then determines appropriate cutting positions that maintain segment composition consistency.
3Ease of manufacture
If conventional image forming apparatus cuts sheet every designated block number, then segmentation is simple, but cutting position becomes inconsistent when printing order changes
Solution Approach 1:
The cutting system transitions from a static fixed-position approach to a dynamic approach where cutting positions are determined based on printing order. The control unit adjusts cutting positions dynamically according to whether normal or reverse order printing is selected, maintaining both simplicity and consistency.
Solution Approach 2:
The system changes the parameter of cutting position based on the printing order parameter. When printing order changes from normal to reverse (or vice versa), the cutting position parameters are相应ly adjusted to maintain consistency in segment composition.

AI summary
An image forming system for printing a sequence of image blocks on a continuous printing sheet based on image data, includes an information processing apparatus and an image forming apparatus. A printing setting unit included by the information processing apparatus designates first information and second information. The first information indicates whether a printing order of the image blocks is to be a normal order or a reverse order. The second information indicates how many image blocks of the sequence are to be printed on each of a plurality of segments of the printing sheet. The image forming apparatus includes a cutting unit and a control unit. The cutting unit cuts the printing sheet. The control unit controls the cutting unit so as to separate the segments of the printing sheet. The control unit determines cutting positions on the printing sheet based on the first information and the second information.
