Solution Overview

Problem

Current color management systems face challenges in efficiently managing color accuracy across multiple printing apparatuses, especially when these devices are remotely located and connected via a network, leading to increased operational burdens on color experts due to differences in conditions such as sheet types and print settings, which can result in inconsistent color verification and adjustment processes.

Innovation Solution

A color management system that includes an information processing apparatus capable of managing multiple print sites, featuring a processor to notify printing apparatuses of changes in color management settings, a color sensor to measure printed images, and a processor to determine if color adjustments are necessary based on preset criteria, with the ability to warn operators if printing settings are not feasible.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If color management settings are changed remotely for multiple printing apparatuses, then color consistency across different locations is improved, but the complexity of managing and notifying all apparatuses increases

Engineering Contradiction:
Improvecolor consistencyVSAvoidmanagement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the color management process into distinct functional modules: setting management unit for creating and storing color management settings, notification unit for transmitting settings to printing apparatuses, and execution unit for performing color verification and adjustment. This segmentation allows each module to handle specific tasks independently, reducing overall management complexity while maintaining color consistency across multiple apparatuses.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The information processing apparatus serves as an intermediary between the color expert and multiple printing apparatuses. It receives color management settings from the expert, stores them in a database, and automatically notifies relevant printing apparatuses of changes. This intermediary role eliminates the need for the expert to manually manage each apparatus, reducing management complexity while ensuring reliable color consistency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If color verification is performed with different sheet types and print settings, then adaptability to various printing conditions is improved, but measurement precision for color accuracy deteriorates

Engineering Contradiction:
Improveprinting condition adaptabilityVSAvoidcolor measurement precision
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system applies local quality by creating specific color management settings tailored to each combination of sheet type and print settings. Instead of using a single universal setting, the database stores multiple specialized settings optimized for local conditions. When a printing apparatus receives a notification, it uses the specific setting matching its current configuration, ensuring both adaptability to various conditions and precision in color verification for each local context.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system manages color management settings with varying parameters including sheet type, print settings, and color verification criteria. By changing and storing multiple parameter combinations in the database, the system adapts to different printing conditions while maintaining precise color measurement for each specific parameter set. The notification unit transmits the appropriate parameter combination to each apparatus based on its current configuration.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If color adjustment operations are performed manually by color experts, then color accuracy is improved, but the time and labor required increase significantly

Engineering Contradiction:
Improvecolor accuracyVSAvoidoperation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system implements preliminary action by having the color expert create and store comprehensive color management settings in advance in the database, covering various sheet types and print settings. When a printing apparatus needs color verification, the notification unit automatically retrieves and transmits the appropriate pre-prepared setting, eliminating the need for manual color adjustment operations at the time of verification. This preliminary preparation maintains color accuracy while significantly reducing operation time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The printing apparatus performs self-service by automatically receiving color management settings notifications, executing color verification using the received settings, and performing color adjustment operations autonomously based on verification results. This automation eliminates the need for continuous manual intervention by color experts, maintaining high color accuracy through systematic processes while dramatically reducing the time and labor required for color management operations.

Inventive Principle:
Principle #25Self-service

AI summary

A color management system includes an external apparatus and a printing apparatus. The external apparatus includes a first controller including a first processor and a first memory to send a color verification setting, including at least sheet information, that is set for a color verification operation, and a color verification execution condition that is set for the color verification operation to the printing apparatus. The printing apparatus includes a second controller including a second processor and a second memory to receive the color verification setting and the color verification execution condition from the external apparatus, print a chart image on a sheet corresponding to the sheet information included in the color verification setting in accordance with having satisfied the color verification execution condition, measure the chart image printed on the sheet, and transmit data obtained by a measurement of the chart image to the external apparatus.
