Print Magnification Control for Sheet Connection Margins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print processing devices face issues with paper size mismatch, leading to unwanted margins when printing images of varying sizes, as they typically use standard paper sizes, resulting in inefficient use of paper and unsightly margins.
Innovation Solution
An information generating device that determines optimal connection lengths between sheets of paper based on image size and paper dimensions, using a connection region determination unit to set magnification ratios and distribute margins evenly, allowing for precise alignment and reduction of unwanted margins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard paper sizes are used for printing, then paper availability and standardization are improved, but image fit and margin reduction deteriorate
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the magnification ratio based on the relationship between image dimensions and paper dimensions. The control unit calculates the appropriate magnification ratio to scale the image so that it fits the paper size precisely, thereby eliminating unnecessary margins while maintaining standard paper size usage.
2Manufacturing precision
If image size is adjusted to fit standard paper, then margin reduction is improved, but image quality and aspect ratio preservation deteriorate
Solution Approach 1:
The patent changes the magnification ratio parameter to scale the image while preserving its aspect ratio. By calculating the magnification ratio based on the smaller dimension match between image and paper, the system ensures the image fits the paper without distortion or unnecessary margins, maintaining both shape integrity and precise fit.
3Productivity
If magnification ratio is set based on paper length in connection direction, then connection length determination is improved, but paper width utilization deteriorates
Solution Approach 1:
The patent applies parameter changes by setting the magnification ratio based on the paper length in the connection direction. The control unit calculates the magnification ratio using the paper length and image length in the connection direction, which determines the connection length between multiple sheets. This approach optimizes the connection process while the system also considers paper width to ensure comprehensive utilization.

AI summary
An information generating device generates data for use in a print processing device capable of printing in a state where sheets are connected to each other, and includes a memory, an input device, and a controller. The memory stores predetermined image data. The input device receives sheet information relating to the sheets which are to be connected to each other by a sheet print processor. The controller sets a magnification ratio indicating either an enlargement ratio or a reduction ratio of the image data, based on a length of the sheet in a second direction orthogonal to a first direction in which sheets are to be connected. In addition, the controller determines a connection length indicating a length of a connection region which is formed between sheets in the first direction, based on the set magnification ratio and the lengths of sheets in the first direction.
