Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses fail to effectively display the positional relationship between images to be printed and processing positions on print media, leading to inaccuracies and inefficiencies in printing operations.
Innovation Solution
A printing apparatus equipped with a display controller that superimposes the image to be printed and processing positions on a preview image, allowing for correction based on the shrinkage ratio of the print medium, and includes a data acquisition section to obtain and correct processing positions, enabling accurate alignment and positioning of images during printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a preview image is displayed showing the image to be printed on the print medium, then the visual representation of printing positions is improved, but the accuracy of processing position alignment deteriorates due to print medium shrinkage not being accounted for
Solution Approach 1:
The system performs preliminary correction of processing positions based on predicted shrinkage ratios before displaying the preview image. By calculating and applying shrinkage compensation in advance to the processing position data, the system ensures that the displayed preview image accurately reflects both the visual layout and the corrected processing positions that will be used during actual printing operations.
Solution Approach 2:
The system incorporates feedback by using detection results from the detection device (which measures actual print medium dimensions) to correct and update shrinkage ratio information. This feedback loop allows the system to continuously refine shrinkage predictions and adjust processing positions accordingly, improving alignment accuracy while maintaining clear visual representation in preview images.
2Manufacturing precision
If processing positions are corrected based on shrinkage ratio, then the manufacturing precision of processing position alignment is improved, but the device complexity increases due to additional correction processes
Solution Approach 1:
The system implements self-service by automatically detecting print medium dimensions, calculating shrinkage ratios, and correcting processing positions without requiring manual intervention. The detection device and control unit work together to autonomously perform measurements, computations, and corrections, reducing the need for complex manual adjustment mechanisms while maintaining high precision.
Solution Approach 2:
The system manages complexity by dynamically adjusting parameters (processing positions and shrinkage ratios) based on detected conditions rather than requiring complex structural changes. By modifying numerical parameters through calculation and correction algorithms, the system achieves high precision without adding mechanically complex components.
3Manufacturing precision
If shrinkage ratio data is acquired and used for correction, then the manufacturing precision is improved, but the loss of time increases due to additional data acquisition and correction steps
Solution Approach 1:
The system performs shrinkage correction in advance during the preview image generation phase rather than during actual printing operations. By calculating and applying shrinkage compensation beforehand, the system minimizes time loss during critical printing operations while maintaining high precision through pre-computed corrected processing positions.
Solution Approach 2:
The system replaces time-consuming manual measurement and calculation processes with automated detection devices and computational algorithms. By using electronic detection and digital correction methods instead of manual procedures, the system significantly reduces the time required for data acquisition and correction while maintaining or improving precision.

AI summary
A printer includes a printing mechanism, a display device, a print controller configured to control the printing mechanism to print an image on a print medium, and a display controller configured to make the display device display a preview image in which the image to be printed on the print medium and a processing position where processing is performed on the print medium after the printing are superimposed with each other.
