Printer Color Adjustment Control Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face significant labor and time challenges when manually adjusting colors in printed images due to poor printer color reproducibility and inefficient color adjustment processes, requiring repeated input of adjustment values and printing.
Innovation Solution
A control apparatus that determines the number of colors designated for adjustment, checks for tendencies in adjustment values, and assesses overlap in influence ranges, recommending adjustments to printer color reproducibility, tone curves, or returning to image editing software to reduce unnecessary manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user manually designates colors and inputs adjustment values one by one, then the user can adjust specific colors in the printed image, but the process requires repeating the adjustment and printing multiple times, consuming a lot of labor and time
Solution Approach 1:
The system automatically analyzes the printed image to detect color deviations and provides feedback by suggesting adjustment values to the user. This feedback mechanism eliminates the need for users to manually trial-and-adjust colors, significantly reducing adjustment time while maintaining color accuracy.
Solution Approach 2:
The system performs automatic color analysis and adjustment value generation without requiring manual user input for each color. The automated color detection and suggestion mechanism serves the adjustment process itself, reducing labor and time consumption while achieving accurate color correction.
2Measurement precision
If the printer's color reproducibility is not correctly adjusted, then the printed image colors deviate from the original, but manually adjusting designated colors requires a lot of effort when the underlying printer calibration is poor
Solution Approach 1:
The system performs preliminary analysis of the printed image to detect color deviations before the user commits to manual adjustments. By automatically identifying which colors need adjustment and suggesting appropriate values, the system prepares the adjustment process in advance, reducing the effort required even when printer calibration is poor.
Solution Approach 2:
The system acts as an intermediary between the poorly calibrated printer and the user by automatically analyzing color deviations and translating them into suggested adjustment values. This intermediary function bridges the gap between printer imperfections and user needs, reducing adjustment effort while maintaining ease of operation.
3Adaptability or versatility
If the user designates multiple colors for adjustment, then more colors can be corrected, but determining the appropriate adjustment values for each color becomes more complex and time-consuming
Solution Approach 1:
The system merges the color analysis function with the adjustment value generation function. By automatically analyzing all designated colors and generating adjustment values for them simultaneously, the system handles multiple colors in a unified process, reducing complexity while maintaining the ability to adjust many colors.
Solution Approach 2:
The system changes the parameter input method from manual user input to automatic system-generated values based on image analysis. This parameter transformation allows multiple colors to be adjusted without increasing process complexity, as the system automatically manages the complexity of determining appropriate adjustment values for each color.
Data Source
AI summary
A control apparatus receives designation of one or more colors to be adjusted in a printed image and input of one or more adjustment values of the designated colors. The printed image is an image output by a printer based on printing image data. The control apparatus makes a color adjustment of the printing image data based on the designated colors and the input adjustment values. The control apparatus includes a hardware processor which makes a determination as to whether or not a number of the colors designated is equal to or greater than a predetermined threshold, and if it is determined that the number of the colors designated is equal to or greater than the predetermined threshold, recommends adjusting color reproducibility of the printer.
