Printed Image Boundary Blending on Complex-Shaped Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing methods result in gaps or overlaps at boundaries between adjacent print image regions, making them conspicuous.
Innovation Solution
The printed matter is formed by transferring ink onto a base body with adjacent print image regions having curved peripheral edges with irregularities, where each edge is disposed within the range of the other region, and the ink density gradually increases from the edge to the center, ensuring seamless integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a picture is divided into multiple print image regions for printing, then printing on complicatedly shaped materials becomes possible, but gaps or overlaps occur at boundaries making them conspicuous
Solution Approach 1:
The printing pad surface is divided into multiple printing regions corresponding to different print image regions. Each region can be independently pressed against the base body, enabling printing on complicated shapes while maintaining control over boundary quality through the curved peripheral edge design
Solution Approach 2:
The peripheral edges of print image regions are designed with curved shapes including irregularities instead of straight lines. This curvature allows the edges to overlap within each other's ranges, creating seamless transitions and making boundaries inconspicuous on the printed surface
2Manufacturing precision
If peripheral edges of adjacent print image regions are made to overlap, then boundaries become inconspicuous, but ink placement precision requirements increase
Solution Approach 1:
The peripheral edges are designed with specific curvature parameters and irregularities that allow overlapping. By controlling the curvature radius and edge profile, the invention ensures that even with manufacturing variations, the overlapping regions create seamless transitions rather than visible boundaries
Solution Approach 2:
Different regions of the printing pad have different surface properties. The peripheral edge regions are specifically designed with curved profiles that facilitate overlapping, while central regions maintain standard printing characteristics. This local differentiation allows boundary regions to blend seamlessly

AI summary
An object is to obtain a printed matter in which a boundary of a print image including a plurality of print image regions is inconspicuous, and a method of manufacturing the printed matter. A printing apparatus is a printed matter formed by transferring ink placed on a printing surface of a printing pad through pressing the printing surface. The printed matter includes a base body and a print image region formed by placing the ink on a surface of the base body. The print image region includes two print image regions disposed adjacent to each other. Each of the two print image regions includes a peripheral edge facing the other of the two print image regions. The peripheral edge of each of the two print image regions has a curved shape including irregularities, and is disposed within a range of the other of the two print image regions.
