Solution Overview

Problem

Existing methods for adjusting print colors on inkjet printers are cumbersome and costly due to the need for laminating protective films and transferring prints to different light sources, leading to inefficiencies in color reproduction and material waste.

Innovation Solution

A method and apparatus that determine a reference color based on designated color information, convert it for different conditions without the protective film, and print a color chart with patches to select the closest color, allowing for accurate color adjustment without laminating the film or transferring the print to the exhibition site.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If protective films are laminated on prints and prints are transferred to exhibition sites for color adjustment, then color reproduction accuracy can be maintained, but the number of processes and material costs increase significantly

Engineering Contradiction:
Improvecolor reproduction accuracyVSAvoidnumber of processes
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates a virtual copy of the color chart by generating image data that represents color patches under different protective film conditions. Instead of physically laminating films and transferring prints to exhibition sites, the system generates simulated color chart images through computer processing, allowing color selection without physical manipulation or site transfers.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent performs preliminary color conversion calculations by determining reference colors and converting them to other reference colors before actual printing occurs. This preliminary action includes calculating color values for multiple protective film types in advance, so when the actual color selection is needed, the system already has prepared data eliminating the need for physical laminating and site transfers.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If protective films are laminated on prints for color adjustment, then color reproduction accuracy is maintained, but material waste increases

Engineering Contradiction:
Improvecolor reproduction accuracyVSAvoidmaterial waste
Core Design Contradiction:
Measurement precisionVSLoss of substance

Solution Approach 1:

The patent creates a virtual copy of the color chart through image data generation, eliminating the need for physical color charts and protective films. The system stores and processes digital representations of color patches under various conditions, replacing physical materials with digital copies that can be reused indefinitely without waste.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent performs preliminary calculations to determine color values for multiple protective film types in advance, storing this data for future use. This eliminates the need to physically laminate protective films during each color selection process, thereby preventing material waste while maintaining color reproduction accuracy.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple color charts with different protective films are prepared for color selection, then color reproduction under various conditions is achieved, but the time required for color adjustment increases

Engineering Contradiction:
Improvecolor reproduction under various conditionsVSAvoidtime for color adjustment
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs preliminary color conversion and data generation for multiple protective film types in advance, storing the results as reference data. When color selection is needed, the system retrieves pre-calculated color values and displays corresponding color charts, eliminating the time-consuming process of physically preparing multiple color charts with different protective films for each selection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates digital copies of color charts under various protective film conditions through image data generation. These virtual copies can be displayed and selected without physical manipulation, allowing users to quickly review and compare color representations under different conditions without the time required for physical preparation and handling of multiple actual color charts.

Inventive Principle:
Principle #26Copying

AI summary

Color reproduction data of a print obtained by forming an image on a print medium corresponding to an input type thereof, and spectral data of a laminate film corresponding to an input type thereof are acquired. A reference color is determined based on color information of a designated color to be reproduced on a protective-film-covered print. Based on the acquired color reproduction data and the acquired spectral data, the determined reference color is converted into another reference color depending on the print without the laminate film thereon. A color value depending on a color patch that is selected as a color closest to the designated color, under a condition where the laminate film is not laminated, from a designated color adjusting color chart printed based on color values depending on the converted other reference color or colors close to the other reference color, is acquired.
