Printer Patch Chart for User-Intended Color Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing devices struggle to perform color calibration based on the user's intended colors, especially when these colors are not among those with high occupancy ratios in the printing target data.
Innovation Solution
A printing device with a display, input unit, and printing engine that allows users to specify objects in a printing target image, generating a patch chart with first patches for specified colors and second patches for predetermined colors, enabling accurate color calibration suited to the user's intention.

1Extent of automation
If color calibration is performed based on colors with high occupancy ratios in printing target data, then the calibration process is automated and efficient, but the user's intended colors may not be properly calibrated
Solution Approach 1:
The system performs preliminary extraction and identification of user-intended colors from printing target data before calibration. By pre-identifying colors specified by the user (such as through color selection tools or designated color swatches in the design software), the system prepares a targeted list of colors that require calibration, ensuring these specific colors are addressed in the subsequent calibration process rather than relying solely on occupancy ratio-based selection.
Solution Approach 2:
The system incorporates feedback mechanisms where the printer measures the actual printed colors using color sensors or spectrophotometers, compares them against the user-intended colors from the printing target data, and adjusts the calibration parameters accordingly. This closed-loop feedback ensures that the calibration accurately reflects the user's color intentions while maintaining automation.
2Ease of operation
If the system extracts colors automatically based on occupancy ratios, then the calibration process is simplified, but it cannot capture specific user-intended colors
Solution Approach 1:
The system integrates multiple functions into a unified calibration process: it can automatically identify colors based on occupancy ratios, detect user-specified colors from printing target data, and perform calibration for both types of colors. This multi-functional approach allows the system to maintain simplicity while adapting to different user needs and color selection methods.
Solution Approach 2:
The calibration system dynamically adapts its behavior based on the input data. It can switch between occupancy-ratio-based color selection and user-intended color selection depending on what is present in the printing target data. The system flexibly adjusts its calibration strategy to match the specific requirements of each printing job, making it both simple to operate and highly adaptable.

AI summary
A printing device includes: a display; an input unit; a printing engine; and a controller. The display is configured to display a printing target image including a plurality of objects. The input unit is configured to input a specified object specified from among the plurality of objects in the printing target image displayed on the display. The printing engine is configured to print the printing target image on a print medium. The controller is configured to perform: a printing operation. The printing operation is to print a patch chart on at least one sheet of print media with the printing engine. The patch chart includes at least one first patch for at least one specified color and a second patch for a predetermined color. Each of the at least one specified color is a color included in the specified object.
