Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If basic proof image data is created without considering ink bleed, then the proof image creation process is simple and fast, but the proof image does not faithfully reproduce the state of printed matter on specific printing media
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing bleed parameters and bleed pattern data for different printing media types before actual proof image creation. When creating a proof image, the system simply retrieves the appropriate bleed parameters and applies the pre-defined bleed patterns, avoiding complex real-time calculations and maintaining both high fidelity and process simplicity.
Solution Approach 2:
The patent implements parameter changes by introducing bleed parameters (such as bleed amount, bleed direction, and bleed intensity) that can be adjusted based on the specific printing medium being used. These parameters modify the basic proof image data to simulate ink bleed effects, allowing the system to adapt to different media characteristics without changing the fundamental proof image creation process.
2Measurement precision
If bleed processing is applied to simulate ink bleed state, then the proof image faithfully reproduces printed matter state, but the processing time and computational load increase
Solution Approach 1:
The system performs preliminary action by pre-defining bleed patterns and characteristics for various printing media types in advance. During proof image creation, it simply applies these pre-established patterns using stored bleed parameters, rather than calculating ink bleed behavior in real-time, thereby maintaining high simulation accuracy while minimizing additional processing time.
Solution Approach 2:
The patent uses copying by creating and storing template bleed patterns that represent typical ink bleed behavior for different printing media. These bleed patterns are then copied and applied to proof images based on the identified media type, avoiding the need to recalculate bleed effects for each individual proof image and significantly reducing computational load.
3Measurement precision
If bleed parameters are introduced to represent ink bleed state, then the proof image data accurately simulates bleed conditions, but the data structure and processing complexity increase
Solution Approach 1:
The patent applies parameter changes by introducing a standardized set of bleed parameters (such as bleed amount, bleed direction angles, and bleed intensity factors) that capture essential ink bleed characteristics. These parameters are organized in a structured format that maps directly to the existing proof image data structure, allowing accurate bleed simulation while maintaining relatively simple data management and processing.
