Print System Wait State for Color Correction Data Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing color correction techniques in image forming systems are uncertain about the correction data used during printing, as they lack clear communication between the host computer and the printer regarding the generation and transmission of correction data.
Innovation Solution
A print system comprising a printer and a computer, where the printer generates and transmits correction data, and the computer corrects print data accordingly, with a wait state maintained until the correction data is transmitted, ensuring appropriate processing and preventing printing until the data is validated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the printer generates correction data during printing, then printing speed is improved, but color accuracy deteriorates because it is uncertain what correction data are used
Solution Approach 1:
The system performs preliminary action by having the printer generate correction data in advance and transmit it to the host computer before printing starts. The host computer stores this correction data and uses it for color correction during printing, ensuring that the correction data generation does not delay the printing process while maintaining color accuracy.
Solution Approach 2:
The host computer acts as an intermediary between the printer's correction data generation and the printing process. It receives, stores, and manages the correction data, then applies it during printing to ensure color accuracy while allowing the printer to operate independently during data generation.
2Manufacturing precision
If the host computer performs color correction processing, then color accuracy is improved, but device complexity increases due to additional communication and coordination requirements
Solution Approach 1:
The printer performs self-service by autonomously generating its own correction data and transmitting it to the host computer. This reduces the burden on the host computer, as it only needs to store and apply the correction data rather than actively managing the entire color correction process, thereby reducing system complexity.
Solution Approach 2:
The system implements feedback by having the printer generate correction data based on its own characteristics and transmit it to the host computer, which then uses this feedback information to perform accurate color correction. This closed-loop approach ensures color accuracy while keeping the system relatively simple.

AI summary
A print system, computer readable media, and printer are provided. The print system includes a printer and a computer. The printer includes a print unit that generates an image on a sheet from output data; a generation unit that generates correction data for correcting print data; and a transmission unit that transmits the correction data to the computer. The computer includes a correction unit that corrects the print data using the correction data transmitted from the transmission unit, thereby generating the output data; and an output unit that outputs the output data to the printer. The printer system also includes a wait state maintain unit that is configured to maintain a wait state so as not to start a printing of the output data corrected in accordance with the correction data generated during a period from a time at which generation of the correction data is commenced by the generation unit until a time at which the transmission unit transmits the correction data.
