Printing Apparatus Opposite-Surface Image and Adhesive Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printed materials lack a three-dimensional appearance and design freedom as the foil and image layer are formed on the same surface, limiting their aesthetic and design capabilities.
Innovation Solution
A printing system that forms an image layer and an adhesive layer on opposite sides of a base material, allowing a foil to be transferred onto the adhesive layer, creating a three-dimensional appearance with different shapes for the image and foil, thereby enhancing design freedom and contrast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a foil is formed on the entire surface of the base material, then the printed material has uniform coverage, but it lacks a three-dimensional appearance and design freedom
Solution Approach 1:
The patent divides the base material into two opposite surfaces, placing the image layer on one surface and the adhesive layer with foil on the other surface. This segmentation allows independent design of image and foil shapes, enabling three-dimensional appearance and high design freedom while maintaining uniform coverage through systematic arrangement.
Solution Approach 2:
The patent transitions from forming both image layer and foil on the same surface (two-dimensional arrangement) to forming them on opposite surfaces of the base material (three-dimensional arrangement). This dimensional change enables the foil to be positioned at a distance from the image, creating three-dimensional appearance and allowing different shapes for image and foil independently.
2Device complexity
If the image layer and adhesive layer are formed on the same surface, then the structure is simple, but the design freedom and three-dimensional appearance are limited
Solution Approach 1:
The patent utilizes the third dimension (depth/thickness of base material) to separate the image layer and adhesive layer onto opposite surfaces. This maintains structural simplicity by using a single base material while dramatically increasing design freedom, as image and foil can now have different shapes and positions without spatial constraints.
3Shape
If multi-layer printing is used to create three-dimensional appearance, then the aesthetic value increases, but the printing time increases
Solution Approach 1:
The patent segments the printing process into two independent single-layer printing operations: one for the image layer on the first surface and another for the adhesive layer on the opposite surface. This avoids the need for complex multi-layer printing on the same surface, reducing printing time while achieving three-dimensional appearance through the spatial separation of layers.
Solution Approach 2:
By utilizing opposite surfaces of the base material, the patent achieves three-dimensional appearance through spatial arrangement rather than through multiple printing layers on the same surface. This dimensional approach reduces the number of printing passes required, thereby reducing printing time while maintaining aesthetic value.

AI summary
A printing apparatus (100) includes a first liquid discharger (106) and a second liquid discharger (106S). The first liquid discharger (106) forms an image layer (11) with a first liquid on a first surface of the base material (10). The image layer (11) includes an image of a first shape. The second liquid discharger (106S) forms an adhesive layer (12) of a second shape with a second liquid on a second surface of the base material (10) opposite to the first surface on which the image layer (11) is formed.
