Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems using standard drivers cannot perform vendor-specific functions like calibration due to performance degradation concerns and increased cost when installing correction modules in printing apparatuses, limiting user functionality and efficiency.
Innovation Solution
A mechanism that allows a computer to execute a control method for generating print data using calibration results, either by utilizing existing modules in the printing apparatus or generating corrected data when such modules are absent, ensuring compatibility and functionality across different vendors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the host computer executes image correction using the calibration result obtained from the printing apparatus, then the calibration function can be provided, but the performance of the host computer may be degraded
Solution Approach 1:
The patent introduces an intermediary mechanism where the host computer sends calibration instructions to the printing apparatus, and the printing apparatus performs the actual image correction using its dedicated correction module. This mediator approach allows the calibration function to be available without requiring the host computer to execute the image correction process, thus avoiding performance degradation.
Solution Approach 2:
The printing apparatus performs self-service by executing the calibration and image correction processes using its own dedicated correction module. The printing apparatus receives calibration instructions from the host computer, then independently completes the correction process, eliminating the need for the host computer to bear the computational burden of image correction.
2Adaptability or versatility
If a correction module is newly installed in the printing apparatus to provide the calibration function, then the calibration function becomes available, but the cost of the printing apparatus increases
Solution Approach 1:
The printing apparatus is designed with a built-in correction module that enables it to perform calibration and image correction independently. This self-service capability allows the printing apparatus to provide the calibration function without requiring the host computer to install additional software or modules, thereby avoiding increased cost for the printing apparatus while maintaining functionality.
Solution Approach 2:
The correction module is pre-installed in the printing apparatus during manufacturing, so that when the printing apparatus receives calibration instructions from the host computer, it can immediately execute the correction process without requiring additional installation or configuration. This preliminary preparation ensures the calibration function is available without incurring additional costs.
3Power
If the printing apparatus executes image correction using the calibration result, then the performance is maintained, but the printing apparatus must have a correction module installed
Solution Approach 1:
The printing apparatus uses its pre-installed correction module to execute image correction independently, maintaining high performance without requiring additional external modules or complex configurations. The correction module is designed to work autonomously when receiving calibration instructions from the host computer, simplifying the overall system architecture.
