Hot-pressing transfer printing method

Abstract

The present invention relates to a hot-press transferring method. In particular, it is a method for transferring image onto cup surface. It includes the following steps: (a) attaching photographic printing paper to said cup surface; (b). using a bubble expelling device to expel the bubble between the photographic printing paper and cup surface; (c) after step (b) firstly using a preheating device to preheat said photographic printing paper and cup surface and moving the image of said photographic printing paper to the front of cup surface, and using a bubble expelling device to expel the bubble between said photographic printing paper and cup surface; (d). after step (c) using a heating device to heat the said photographic printing paper and said cup surface to transfer the image of said photographic printing paper onto the cup surface; and (e). after step (d) removing said photographic printing paper from said cup surface.

Description

technical field [0001] The invention provides a method of hot press transfer printing, especially a method for transferring an image on a photographic paper to a cup of noodles. Background technique [0002] After the mass production technology matured in the industrial society, all kinds of products gradually moved towards differentiated designs, so the demand for appearance design and personalized products came into being. Nowadays, various personalized products are sold in many different forms, such as Transferring personal life photos to various products such as mugs (Mug), clothes, backpacks, stationery, etc., but there is still much room for improvement in the transfer quality, especially since the surface of the transfer items is not uniform When the surface is flat but curved, such as cups and other cylindrical objects, often the photo paper and the cup surface cannot be tightly attached during transfer, resulting in poor transfer quality. Today, consumers are using...

Problems solved by technology

One is to paste the photo paper on the surface of the mug, then heat it, and when the photo paper and the mug are still at high temperature, tear off the photo paper to observe whether the image on the photo paper is affected by the air bubbles and has not been completely transferred to the mug. On the mug, if the image is not completely transferred, then paste the photo paper back, put it in a heat press and transfer it again. In this way, operating under high temperature conditions is not only dangerous to a certain extent, but also easily causes overlapping images Distortion; the second is to paste the photo paper on the surface of the mug, then heat it, and when the photo paper and the mug are still at high temperature, use a scraper to remove the air bubbles that exist between the cup surface and the photo paper on the back of the photo paper However, this method is not only dangerous to a certain extent because it is operated under high temperature conditions, but also often results in some areas between the photo paper and the mug being scraped, while some areas are not scraped, or even The scraped air bubbles escape to the area that has been scraped off; moreover, if the mug transfer is poor and needs to be re-transferred, use nail polish remover and a thin cloth to remove the old bad pattern

And above-mentioned method is except the waste that causes on the time, also is not easy to control on quality.
