Solution Overview

Problem

Conventional card issuing systems impair the design quality of cards by making transparent overcoat printed parts conspicuous, as they apply overcoat printing uniformly or only based on the print range, failing to address the specific requirements of design quality and durability for various types of cards.

Innovation Solution

A card issuing system that generates overcoat data based on pixels for areas requiring design quality and covers areas needing durability, allowing for customizable overcoat application without compromising the card's design, using a print image generation portion, overcoat image generation portion, and combining portion to manage print and overcoat data effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If uniform overcoat printing is applied to protect the print, then the durability of the card is improved, but the design quality of the card is impaired due to conspicuous overcoat printed parts

Engineering Contradiction:
ImprovedurabilityVSAvoiddesign quality
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent applies different overcoat printing treatments to different regions of the card based on their specific requirements. Design-sensitive areas receive pixel-based overcoating that matches the print pattern, while durability-critical areas receive full-area overcoating. This local differentiation resolves the contradiction by allowing each region to have the appropriate level of protection without compromising overall design quality.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments the card surface into multiple regions with different overcoat requirements. By dividing the printing area into design-quality zones and durability zones, the system can apply customized overcoat strategies to each segment, thereby achieving both aesthetic preservation and protective coverage where needed.

Inventive Principle:
Principle #1Segmentation

2Reliability

If overcoat printing is applied based on print range, then the print protection is improved, but the design quality is still impaired because the overcoat area is too large

Engineering Contradiction:
Improveprint protectionVSAvoiddesign quality
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

Instead of applying overcoat uniformly across the entire print range, the patent applies pixel-based overcoating only to specific pixels within the print area that require protection. This localized approach ensures print protection while minimizing the visible overcoat area, thereby preserving design quality.

Inventive Principle:
Principle #3Local quality

3Manufacturing precision

If pixel-based overcoating is applied to design-sensitive areas, then the design quality is maintained, but the processing complexity increases

Engineering Contradiction:
Improvedesign qualityVSAvoidprocessing complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent segments the processing into two distinct pathways: pixel-based processing for design-sensitive areas and full-area processing for durability-critical areas. This segmentation allows the system to apply complex pixel-level operations only where necessary, thereby managing processing complexity while maintaining design quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of applying pixel-based overcoating to the entire card surface, the patent applies this computationally intensive method only to design-sensitive regions. This partial application reduces overall processing complexity while still achieving the desired design quality preservation in critical areas.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

According to an embodiment, a card issuing system which issues cards includes: a print image generation portion which generates print data to perform printing on the card; an overcoat image generation portion which generates overcoat data, which is data on an overcoat for the print data generated by the print image generation portion; and a printing portion which performs printing of the print data generated by the print image generation portion, and the overcoat data generated by the overcoat image generation portion on the card. The overcoat image generation portion generates the overcoat data with which an area where a design quality is required in the print data is subjected to overcoating based on pixels to be printed by the print data, and an area where durability is required in the print data is subjected to overcoating which covers the area.
