Printed Matter Base Layer for Removable Print Without Peeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Print layers in printed matter tend to easily peel off from the base material when the quality meets predetermined criteria, necessitating a method to ensure the print layer can be removed without detachment.
Innovation Solution
A method involving a base layer forming step, print layer forming step, print quality checking step, and post-processing step, where a removable base layer is formed on the base material, followed by forming a print layer and optionally a coating layer, with the print layer being removable based on quality checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a print layer is formed directly on the base material to ensure strong adhesion, then the print layer does not easily peel off, but the print layer cannot be removed for reuse of the base material
Solution Approach 1:
The invention divides the original single-layer structure into two distinct layers: a base layer formed on the base material, and a print layer formed on the base layer. This segmentation allows the print layer to be removed from the base layer without detaching the base layer from the base material, enabling base material reuse while maintaining adhesion strength through the base layer's design.
2Adaptability or versatility
If a removable base layer is formed on the base material, then the print layer can be removed for base material reuse, but the print layer may easily peel off during normal use
Solution Approach 1:
The base layer acts as an intermediary between the base material and the print layer. It provides a stable bonding interface to the base material while allowing controlled removal of the print layer. The base layer's composition and structure are designed to maintain print layer stability during normal use, preventing peeling, while enabling removal when reuse is required.
3Ease of manufacture
If the print layer is made of ink that can be dissolved by solvent for removal, then the base material can be reused, but the print layer has low adhesion to the base material and easily peels off
Solution Approach 1:
The invention separates the removal function from the adhesion function by creating distinct layers. The base layer is designed with solvent-soluble properties enabling easy removal, while the print layer maintains strong adhesion to the base layer. This segmentation allows the soluble base layer to facilitate removal without compromising the adhesion of the print layer during normal use.

AI summary
There is provided a method for manufacturing printed matter having a print layer that can be removed from a base material but does not easily peel off from the base material. A method for manufacturing printed matter includes: a base layer forming step; a print layer forming step; a print quality checking step; and a post-processing step. In the base layer forming step, a base layer which is removable from a base material is formed on a front surface of the base material. In the print layer forming step, a print layer is formed on a surface of the base layer on a side opposite to the base material. In the print quality checking step, a quality of the print layer is checked. In the post-processing step, a coating layer that coats the print layer is formed or the print layer is removed together with the base layer from the base material depending on the quality of the print layer.
