Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing printing methods, particularly ink-jetting, often experience bleeding between adjacent different color inks due to low absorbability of the base material, use of aqueous inks, or layering of color and clear inks, leading to color mixing and visibility issues.

Innovation Solution

The solution involves printing different color inks with a clearance between them, which can be achieved by adjusting the printing process to form a gap between the colors, thereby preventing bleeding. This method can be applied to various base materials, including plastic films, using ink-jetting technology with aqueous inks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If different color inks are adjacently used without clearance to print images, then printing coverage and productivity are improved, but bleeding between adjacent different colors occurs causing color mixing

Engineering Contradiction:

Improveprinting coverageVSAvoidcolor boundary precision

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The invention divides the printed area into multiple regions including first colored areas, second colored areas, and intermediate areas positioned between them. This segmentation prevents direct contact between adjacent different colors, eliminating bleeding while maintaining high printing coverage and productivity.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If ink-jetting is used to eject microscopic ink drops for printing, then printing flexibility and adaptability are improved, but bleeding between adjacent colors is likely to occur

Engineering Contradiction:

Improveprinting flexibilityVSAvoidcolor separation precision

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The invention introduces intermediate areas as buffer zones between first colored areas and second colored areas. These intermediate areas act as mediators that prevent direct interaction between adjacent different colors, eliminating bleeding while preserving the flexibility of ink-jetting printing methods.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Manufacturing precision

If printing is performed on base material with no or low absorbability, then printing quality on plastic films is improved, but bleeding between colors is markedly observed

Engineering Contradiction:

Improveprinting quality on plastic filmVSAvoidcolor bleeding

Core Design Contradiction:

Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

By segmenting the printed design into separated colored areas with intermediate areas between them, the invention prevents ink migration between colors on low-absorbability plastic film surfaces, maintaining both printing quality and color integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The intermediate areas serve as protective buffers between adjacent different colors on plastic film, preventing direct ink contact and eliminating bleeding while preserving the ability to print on low-absorbability surfaces.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Ease of operation

If aqueous ink is used for printing, then environmental friendliness and ease of operation are improved, but bleeding between different colors is likely to be caused

Engineering Contradiction:

Improveease of printingVSAvoidcolor boundary precision

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The intermediate areas introduced in the invention act as protective barriers between adjacent different colors when using aqueous inks, preventing capillary action and ink migration that cause bleeding, while maintaining the ease of operation associated with aqueous ink printing.

Inventive Principle:

Principle #24Intermediary (Mediator)
