Standard Class Driver Color Gamut Conversion for Accurate Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printer drivers, particularly standard class drivers, lack the ability to execute a color conversion function, which prevents printing in consideration of the color gamut of the printing device, making it difficult to convert print data into a color gamut reproducible by the printing device.
Innovation Solution
A non-transitory computer-readable storage medium storing a program that enables a control method to execute a color conversion function, allowing the conversion of print data color gamut into a reproducible color gamut by the printing device through a mechanism that includes a display control step for setting reception and an execution step for the color conversion function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard class driver is used for printing, then compatibility with multiple printing devices is improved, but the ability to execute color conversion function deteriorates
Solution Approach 1:
The patent introduces a color conversion function execution unit as an intermediary component between the standard class driver and the printing device. This unit acts as a mediator that enables color conversion functionality without requiring vendor-specific driver modifications, thus maintaining compatibility while adding the missing color conversion capability.
Solution Approach 2:
The patent makes the color conversion function executable within the universal standard class driver framework, allowing one driver to serve multiple printing devices from different vendors while incorporating color conversion capabilities. This eliminates the need for separate vendor-specific drivers for color conversion.
2Reliability
If vendor-specific printer driver is used, then color conversion function can be executed, but installation complexity and device compatibility deteriorates
Solution Approach 1:
The patent integrates color conversion functionality into the universal standard class driver, allowing a single driver to work with multiple printing devices from different vendors. This eliminates the need for separate vendor-specific drivers and simplifies installation while maintaining color conversion capabilities.
Solution Approach 2:
The patent extracts the color conversion function execution unit as a separate, standardized component that can be independently implemented within the standard driver framework. This separation allows color conversion to be provided universally without requiring complex vendor-specific driver installations.
3Productivity
If color conversion function is not executed, then printing process is simpler, but color gamut accuracy deteriorates
Solution Approach 1:
The patent performs color conversion as a preliminary action before the actual printing process. The color conversion function execution unit converts the color gamut of print data to match the printing device's capabilities in advance, ensuring color accuracy without adding complexity to the subsequent printing operations.
Solution Approach 2:
The color conversion function execution unit serves as an intermediary processing step between print data generation and physical printing. It transforms color data to match device capabilities, ensuring accurate color reproduction while maintaining a clean separation from the core printing process.

AI summary
A control method for converting color gamut of print data into color gamut reproducible in printing. A setting reception screen for receiving a setting of a color conversion function for converting a color gamut of print data to be printed by a printing device into a color gamut reproducible in printing by the printing device is displayed, and the color conversion function received on the setting reception screen is executed.
