Color Verification Tolerance Screening for Commercial Printers

Solution Overview

Problem

Existing color management systems in commercial printers often fail due to stringent tolerance values exceeding printer performance, leading to frequent color verification failures and inefficient color correction processes.

Innovation Solution

An information processing device that performs preliminary verification of user-set tolerance values by comparing them to predetermined thresholds, ensuring they fall within acceptable ranges before registering color verification specifications, thereby preventing inappropriate tolerance settings that cause failures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If stringent tolerance values are set for color verification, then color accuracy requirement is improved, but color verification success rate deteriorates

Engineering Contradiction:

Improvecolor accuracyVSAvoidcolor verification success rate

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The system performs preliminary verification of tolerance values by comparing them against predetermined thresholds before actual color verification. This preliminary action identifies and flags tolerance values that are too stringent, preventing verification failures before they occur and allowing users to adjust inappropriate values.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to users when tolerance values exceed predetermined thresholds, indicating that these values are too stringent. This feedback mechanism guides users to adjust tolerance values to appropriate levels, balancing color accuracy requirements with verification success rates.

Inventive Principle:

Principle #23Feedback

2Manufacturing precision

If tolerance values are set too strict, then color accuracy standard is improved, but frequency of color verification failures increases

Engineering Contradiction:

Improvecolor accuracy standardVSAvoidcolor verification efficiency

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The system performs preliminary verification of tolerance values by comparing them against predetermined thresholds before actual color verification. This preliminary action identifies and flags tolerance values that are too stringent, preventing verification failures before they occur and allowing users to adjust inappropriate values.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system converts the potential harm of overly strict tolerance values (which cause verification failures) into a benefit by using predetermined thresholds to guide users toward appropriate tolerance settings. The threshold comparison mechanism transforms what would be failure-prone strict standards into a productive verification process.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Measurement precision

If color verification is performed with inappropriate tolerance values, then color accuracy check is performed, but unnecessary correction processing increases

Engineering Contradiction:

Improvecolor accuracy verificationVSAvoidcorrection processing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary verification of tolerance values by comparing them against predetermined thresholds before actual color verification. This preliminary action identifies and flags tolerance values that are too stringent, preventing verification failures before they occur and allowing users to adjust inappropriate values.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables users to self-correct inappropriate tolerance value settings by providing clear feedback when values exceed thresholds. Users can independently adjust tolerance values to appropriate levels without requiring external intervention or repeated verification attempts, reducing time loss from unnecessary corrections.

Inventive Principle:

Principle #25Self-service

AI summary

An information processing device control method for performing color measurement on a color patch arranged on a chart printed out from an image forming apparatus to verify color accuracy of the image forming apparatus is provided, which accepts a color verification specification regarding color accuracy verification, determines whether or not a tolerance value set in the accepted color verification specification is within an acceptable range, and registers the color verification specification if the set tolerance value is determined to be within the acceptable range.
