Solution Approach 1:

The system performs automated color conversion and separation without requiring manual operator intervention. The server automatically converts RGB/CMYK data to xCLR format, generates calibration diagrams, and manages the printing process, making the system self-sufficient and eliminating the need for skilled operators to perform complex manual conversions

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical processes (operators physically performing color separation and conversion) with an automated digital system. The server apparatus automatically performs color space conversions, generates xCLR separated files, and manages calibration data, substituting human operators with automated computational processes

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If automated conversion from RGB/CMYK to xCLR format is implemented, then operator sensitivity is reduced, but system complexity increases

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system incorporates calibration diagrams that are printed and measured to provide feedback on the actual printing conditions. This feedback is used to automatically adjust and optimize the color conversion profiles, ensuring consistent results across different printing sessions and materials without requiring manual intervention

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary calibration by printing test diagrams and measuring them before actual production printing. This preliminary action establishes the correct color profiles and conversion parameters in advance, ensuring that subsequent printing operations produce consistent results without requiring operators to manually adjust settings

Inventive Principle:
Principle #10Preliminary action

3Productivity

If manual file management processes are used, then operators can manage printing data, but data safety and processing efficiency are compromised

Engineering Contradiction:
Improveprocessing efficiencyVSAvoiddata safety
Core Design Contradiction:

Solution Approach 1:

The patent replaces manual file management processes with an automated server-based system. The server automatically manages color conversion files, calibration data, and printing parameters, eliminating manual file handling and improving both efficiency and data safety through automated processes

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The server apparatus acts as an intermediary between the input data and the printing process. It automatically manages all file conversions, stores calibration data, and coordinates the printing operations, serving as a centralized mediator that improves data safety and processing efficiency by eliminating direct manual intervention

Inventive Principle:
Principle #24Intermediary (Mediator)
