Print Information Processing Apparatus Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ink-jet printing technologies face an increase in data transmission bandwidth due to independent transmission of ink amount and overprinting order information, leading to inefficiencies in data processing.
Innovation Solution
A print information processing apparatus that combines print level information and print timing information to generate reduced data output, replacing part of the print level information with print timing information when the ink amount is not maximum or minimum, thereby reducing the overall data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If print level information and print timing information are transmitted independently, then the completeness of print information is improved, but the data transmission bandwidth increases
Solution Approach 1:
The patent combines print level information and print timing information into a single integrated data structure. The print head control information includes both the ink amount (print level) and the ejection timing for each nozzle in a unified format, eliminating the need for separate transmission channels and reducing overall bandwidth requirements while maintaining complete print control information.
2Quantity of substance
If the data bus bandwidth is enlarged to transmit independent print information, then the transmission capacity is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple information streams (print level and print timing) into a single integrated data bus transmission protocol. This consolidation allows the system to maintain full transmission capacity without requiring multiple separate data buses or complex multi-channel communication infrastructure, thereby reducing device complexity.
Solution Approach 2:
The integrated print information structure serves multiple functions simultaneously: it encodes both the amount of ink to be ejected and the timing of ejection for each nozzle. This multi-functional data structure eliminates the need for specialized separate channels for different types of print control information, simplifying the overall data bus architecture.

AI summary
A print level information generating unit generates print level information representing the amount of ink to be applied to a predetermined area on a print medium. A print timing information generating unit generates print timing information indicating a timing, at which the ink is applied to the predetermined area. A print information combining unit outputs the print level information as the print information in a case where the amount of ink to be applied to the predetermined area is maximum or minimum. Moreover, the print information combining unit replaces a part of the print level information with at least a part of the print timing information so as to output, as the print information, information obtained by combining the print timing information and the print level information in a case where the amount of ink to be applied to the predetermined area is not maximum or minimum.
