Poster Printing Control Apparatus for Image Division and Scale Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing poster printing techniques require users to go back and forth between applications to adjust image sizes and positions, leading to potential formation of unnecessary white spaces on roll paper.
Innovation Solution
A control apparatus and method that allows users to efficiently set and process poster printing by dividing images into multiple print media, using a setting unit to determine the number of divisions, obtaining the print media width, and calculating a scale factor to avoid white spaces through a display control unit that shows a preview screen for processing instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users use general drawing applications to complete drawing data in advance, then the image can be prepared for poster printing, but the user has to go back to the application screen to change image size and position if the print result is not desired
Solution Approach 1:
The patent merges the poster printing control functions directly into the drawing application interface. The setting unit, obtaining unit, determining unit, and display control unit are integrated into the existing drawing application, allowing users to perform poster printing setup and image adjustment within the same application environment without switching between multiple applications.
Solution Approach 2:
The system provides self-service capabilities by automatically calculating scale factors and displaying preview screens with processed images. When users instruct processing through the processing instruction item, the system automatically determines the appropriate scaling and displays the result, eliminating the need for manual intervention in multiple applications.
2Manufacturing precision
If users drag the image on the print preview to change size and position, then the print result can be adjusted, but unnecessary white spaces may be formed on the roll paper
Solution Approach 1:
The display control unit provides visual feedback by showing a preview screen that displays the processed input image reflecting the processing based on the processing instruction. This allows users to see exactly how the image will be scaled and positioned before printing, enabling precise adjustment without forming unnecessary white spaces.
Solution Approach 2:
The determining unit automatically calculates and adjusts the scale factor parameter based on the set number of divisions, width of the print medium, and width of the input image. This parameter adjustment ensures optimal utilization of the roll paper width while maintaining image quality, preventing unnecessary white spaces.

AI summary
Provided is a technique that enables efficient setting of poster printing and efficient processing of an image. To this end, a control apparatus of the present invention is a control apparatus that allows a printing apparatus to print multiple divided images, into which an input image is divided, on print media, including: a setting unit that sets the number of divisions of the input image based on user input; an obtaining unit that obtains a width of the print media; a determining unit that determines a scale factor of the input image based on at least the set number of divisions, the width of the print medium, and a width of the input image; and a display control unit that displays a preview screen of the input image and a processing instruction item for instructing processing of the input image together, in which in a case where processing of the input image is instructed by user operation through the processing instruction item, the display control unit displays a processed input image reflecting the processing based on the processing instruction, and the determining unit determines a scale factor of the processed input image based on a width of the processed input image.
