Image Preview Color Distinction for White Toner on Colored Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing systems fail to distinguish between white areas specified in print jobs and the background of the recording medium, leading to indistinguishable preview images, especially when white toner is used on colored backgrounds.
Innovation Solution
An image processing apparatus that determines the display color of a drawing area corresponding to a recording medium as a color other than white when a white color material is specified, using available color materials and considering the color of the recording medium to simulate the actual print appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If white toner is used on colored recording medium backgrounds, then the print output achieves the desired white areas, but the preview image cannot distinguish between white areas and the recording medium background
Solution Approach 1:
The patent applies color changes by displaying the recording medium background in its actual color (e.g., yellow for yellow toner) rather than always showing it as white. When white toner is specified, the background area is displayed in the recording medium's actual color to distinguish it from true white areas, while non-white areas maintain their intended colors. This resolves the contradiction by making the preview accurately represent what will be printed while maintaining visual distinction between different areas.
2Ease of operation
If the background is displayed in white, then the preview image appears clean and simple, but it becomes indistinguishable from white areas specified in the print job
Solution Approach 1:
The patent applies local quality by differentiating the display treatment of different areas: the recording medium background is displayed in its actual color (e.g., yellow), while white areas specified in the print job are displayed in white. This localized differentiation allows both areas to be visually distinct in the preview, resolving the contradiction between simplicity and accuracy by applying different display qualities to different regions based on their semantic meaning.

AI summary
An image processing apparatus includes a display control unit that displays, on a display unit, a first area, in which a display image generated from print data included in a print job subjected to printing performed by an image forming apparatus is to be disposed, a second area, which corresponds to a recording medium on which an image to be printed corresponding to the display image is recorded and in which the display image is to be disposed, and a third area, which corresponds to a background of the recording medium and includes the second area, an identification unit that identifies a color of the recording medium specified by attribute information that specifies a process performed by the image forming apparatus in accordance with the print job, a setting unit that sets a background image of the recording medium, and a generation unit that generates the display image.
