Image Processing Apparatus Line Width Correction by Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing systems face issues where line widths for different colors are not consistently reproduced across various printing apparatuses due to variations in ink application, leading to differences in line width output.
Innovation Solution
An image processing apparatus that acquires drawing commands, determines correction amounts based on line color, and adjusts line widths accordingly to match the target line width, using tables or lookup tables to account for ink application variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If ink application amount is reduced for pale color lines, then ink usage is optimized, but line width becomes thinner than intended
Solution Approach 1:
The system performs preliminary analysis of the line color and determines the appropriate ink application amount before printing. By pre-calculating the ink quantity based on color characteristics, the system optimizes ink usage while maintaining the intended line width, resolving the contradiction between ink conservation and printing precision.
2Manufacturing precision
If ink application amount is increased for dark color lines, then line width is maintained, but ink usage increases
Solution Approach 1:
The system dynamically adjusts the ink application amount parameter based on the color characteristics of each line. By changing the ink quantity parameter according to color depth requirements, the system maintains accurate line width representation while optimizing ink consumption, preventing both over-inking and under-inking scenarios.
3Manufacturing precision
If color-specific ink application is implemented, then line width accuracy is improved, but processing complexity increases
Solution Approach 1:
The system applies different ink application characteristics to different color lines based on their local requirements. Each color receives customized ink treatment tailored to its specific needs, ensuring optimal line width accuracy for each color while maintaining overall system efficiency through localized optimization rather than uniform processing.

AI summary
An object is to reduce a difference between a target line width and a width of a line that is printed by a printing apparatus by correcting the line width in accordance with color information indicating a color of the line in a case where an image is printed by the printing apparatus based on image data including the line based on print data. The present disclosure is an image processing apparatus having an acquisition unit configured to acquire a drawing command in which a color and a line width of a line are specified, a determination unit configured to determine a correction amount for correcting the line width specified in the drawing command based on the color of the line specified in the drawing command, and a correction unit configured to correct the line width specified in the drawing command in accordance with the correction amount.
