Print Speed Enhancement via Pre-Processed Data Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses, such as printers, experience significant slowdowns in print speed due to the time-consuming process of interpreting and processing large quantities of color and pattern information, leading to repetitive operations that decrease efficiency.
Innovation Solution
Implementing a print speed enhancing mode that allows for pre-processing of print data, storing anticipated result values in a storage unit, and using these values to generate print data without additional processing when a print command is received, thereby avoiding repetitive operations and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the image forming apparatus performs real-time color conversion and pattern generation for each print command, then processing accuracy is maintained, but print speed decreases sharply
Solution Approach 1:
The patent performs color conversion and pattern generation in advance before actual printing. A pre-processing unit converts input data to print data and generates anticipated result values (including color corrections and pattern information) before the print command is executed. These pre-processed values are stored and reused during actual printing, eliminating the need for real-time processing and significantly improving print speed.
2Productivity
If the image forming apparatus processes all color and pattern information in real-time, then output quality is maintained, but operational efficiency decreases due to repetitive operations
Solution Approach 1:
The patent creates copies of processed data in the form of anticipated result values. The pre-processing unit generates these result values (including color conversion results and pattern information) and stores them in a storage unit. During subsequent print operations, the system retrieves and uses these stored copies instead of reprocessing the original data, thereby eliminating repetitive operations and improving operational efficiency.
3Manufacturing precision
If the image forming apparatus performs complete color conversion (RGB to CMYK) and pattern generation for every print command, then print accuracy is maintained, but processing time increases
Solution Approach 1:
The patent performs the complete color conversion process (RGB to CMYK) and pattern generation in advance during a pre-processing stage. The pre-processing unit executes the full color conversion algorithm and generates accurate anticipated result values before printing. These pre-converted values are then stored and directly used during actual print operations, maintaining color accuracy while eliminating time-consuming real-time processing.

AI summary
A print data processing method of an image forming apparatus that has a storage unit includes: setting at least one print speed enhancing mode; performing a pre-processing corresponding to the set print speed enhancing mode; and processing the print data by using a result of the pre-processing.
