Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Screen printing is time-consuming and costly due to the need for multiple screens to produce multicolor images, and existing heat and pressure transfer methods are inefficient for creating full-color designs.
Innovation Solution
A method involving a transfer medium with registration marks, where an image is printed on a release film, covered with a backing and adhesive layer, and then cut using a cutting device aligned by the registration marks, allowing for the transfer of images to a substrate using heat and pressure without the need for multiple screens or masks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If screen printing is used to produce multicolor images, then color variety is improved, but manufacturing time and cost increase due to multiple screens
Solution Approach 1:
The patent combines multiple color printing operations into a single screen by incorporating multiple color inks (e.g., cyan, magenta, yellow, black) and their respective stencils on one screen. This merging eliminates the need for multiple separate screens, reducing manufacturing time while maintaining full-color capability.
Solution Approach 2:
The patent segments the color printing process by assigning different colors to specific regions or layers on a single screen, allowing simultaneous printing of multiple colors in one pass. This segmentation enables full-color output without requiring sequential printing through multiple screens.
2Adaptability or versatility
If multiple screens are used for multicolor screen printing, then color variety is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges multiple color printing functions into a single screen structure by integrating multiple color inks and stencils on one substrate. This reduces device complexity from multiple screens to one screen while maintaining the ability to produce multicolor images.
Solution Approach 2:
The single screen in the patent performs multiple functions by simultaneously handling multiple colors and design elements that would traditionally require separate screens. This multi-functionality reduces the overall number of screens needed while expanding color variety.
3Productivity
If heat and pressure transfer methods are used, then transfer efficiency is improved, but color accuracy and detail are lost
Solution Approach 1:
The patent optimizes the parameters of heat and pressure application (temperature, pressure duration, pressure distribution) to achieve complete ink transfer while preserving color accuracy and fine details. By carefully controlling these parameters, the method maintains manufacturing precision while achieving high transfer efficiency.
Solution Approach 2:
The patent creates a precise copy of the original design on the substrate through the transfer medium, maintaining color accuracy and detail by using a stencil that exactly replicates the desired pattern. The heat and pressure process then faithfully reproduces this copy without loss of precision.

AI summary
The present disclosure provides a method for transferring an image to a substrate that includes providing a transfer medium having at least one registration mark; printing an image on the transfer medium; covering the image with a backing layer, the backing layer not covering the registration mark; covering the backing layer with an adhesive layer; penetrating the adhesive layer and the backing layer with a cutting device at locations around the image, the penetrating of the adhesive layer and backing layer not penetrating the transfer medium; removing portions of the adhesive layer and backing layer from the locations around the image; and transferring the image to the substrate.
