Dynamic Color Gamut Adjustment for Printer Settings

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In image processing, when a specified color is outside the color gamut of a printer, the editing device must change the color to one within the gamut, potentially resulting in a printed color that is distant from the original specification.

Innovation Solution

A method and device that acquire a specified color, determine if it is within the printer's color gamut, and if not, display alternative print settings that minimize the distance between the specified color and the gamut, allowing the printer to produce a color closer to the original specification by adjusting settings such as resolution and pretreatment processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the editing device changes the specified color to a color within the printer's color gamut, then the color can be printed, but the printed color may be distant from the specified color

Engineering Contradiction:

Improvecolor reproduction accuracyVSAvoidcolor gamut constraint

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The system dynamically adjusts print settings (resolution, pretreatment processing, ink concentration) to expand or modify the effective color gamut, allowing the specified color to be reproduced more accurately without simple gamut mapping

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes multiple print parameters simultaneously (resolution, pretreatment processing type, ink concentration) to achieve the target color, rather than changing only the color values themselves

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the printer uses the first print settings with a larger color gamut, then more colors can be reproduced, but the device complexity increases

Engineering Contradiction:

Improvecolor gamut coverageVSAvoidprint settings complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the color reproduction problem into multiple independent print settings (resolution, pretreatment processing, ink concentration) that can be adjusted separately to achieve the desired color gamut expansion

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system makes existing print settings serve multiple functions - they not only control print quality but also dynamically adjust the color gamut to match the specified color requirements

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A non-transitory computer-readable medium stores computer-readable instructions. The instructions instruct a computer to perform processes including an acquisition step, a determination step, and a display step. The acquisition step includes acquiring a specified color. The determination step includes determining whether a device-independent color based on the specified color is present within a first color gamut based on first print settings of a printer. The display step includes displaying, when it is determined that the device-independent color is not present within the first color gamut, second print settings of the printer. The second print settings are different from the first print settings and cause a distance between the device-independent color and a second color gamut that is based on the second print settings to be smaller than a distance between the device-independent color and the first color gamut.
