Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing and printing apparatuses require significant time for high-resolution overcoat and undercoat processing, which hampers efficiency in ink application and image stabilization.
Innovation Solution
An image processing apparatus comprising high-resolution and low-resolution rasterizing processors generates coating data with lower resolution, reducing processing time by separating print data generation from coating data generation, allowing for efficient ink application and image stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution rasterization is used for coating data generation, then image quality is improved, but processing time increases significantly
Solution Approach 1:
The patent divides the data processing into two separate pathways: a high-resolution pathway for print data generation and a low-resolution pathway for coating data generation. This segmentation allows each pathway to operate at its optimal resolution level, preventing the coating data generation from being bottlenecked by high-resolution requirements while maintaining image quality where needed.
Solution Approach 2:
The patent applies different resolution qualities to different parts of the processing system. The print data generating section uses high-resolution rasterization to maintain image quality, while the coating data generating section uses low-resolution rasterization to reduce processing time. This local differentiation of quality levels resolves the contradiction between image quality and processing time.
2Reliability
If thickening is performed by one pixel around the image, then coating coverage is improved, but processing time increases
Solution Approach 1:
The patent changes the resolution parameter for coating data generation from high-resolution to low-resolution. This parameter change allows the system to achieve adequate coating coverage through the low-resolution thickening process while significantly reducing the processing time required for thickening operation.
3Productivity
If separate processing sections are used for print data and coating data, then processing efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the processing system into distinct sections: a high-resolution rasterizing processor for print data, a low-resolution rasterizing processor for coating data, and separate generating sections for each. This segmentation improves processing efficiency by allowing parallel operation at different resolutions while the modular architecture keeps the added complexity manageable.

AI summary
A print-data generating section generates print data in accordance with a high-resolution raster image generated by a high-resolution rasterizing processor. A low-resolution rasterizing processor generates a low-resolution raster image having lower resolution than that of the high-resolution raster image. An overcoating-data generating section generates coating data in accordance with the low-resolution raster image. Overcoating data is handled with low resolution, resulting in less processing time for overcoating than when the overcoating-data is handled with high resolution.
