Problems solved by technology
One is to paste the photo paper on the cup noodles with the handle, preheat it first, and when the photo paper and the cup with the handle are still at high temperature, tear off the photo paper and observe whether the image on the photo paper is still there Affected by air bubbles and not completely transferred to the large cup with a handle, if the image is not completely transferred, then paste the photo paper back, put it in a heat press and transfer it again, so that it is operated under high temperature conditions, except for those with In addition to being dangerous to a certain degree, it is also easy to cause image overlap and distortion; the second is to paste the photo paper on the cup noodles with the handle, preheat it first, and keep the photo paper and the cup with the handle still in a high temperature state. Next, use a scraper to scrape off the air bubbles existing between the cup surface and the photo paper on the back of the photo paper. However, because this method is operated under high temperature conditions, it is not only dangerous to a certain extent, but also often causes the photo paper to be damaged. Some areas between the large cups are scraped, while some areas are not scraped, and even the scraped air bubbles escape to the area that has been scraped; moreover, if there is a large cup with poor transfer, it needs to be retransferred When printing, use nail polish remover and a thin cloth to remove old bad patterns
And above-mentioned method is except the waste that causes on the time, also is not easy to control on quality.

A method for removing the air bubbles between the surface of cup and photo paper during hot transfer of the image from photo paper onto cup surface features that after said photo paper is attached onto cup surface, a roller is used to roll on the photo paper for expelling the air bubbles between photo paper and cup surface.
Description
technical field [0001] The invention relates to a method for removing air bubbles between the cup surface of a cup and photo paper, in particular to a method for removing air bubbles between the photo paper and the cup surface when the photo paper carries out thermal pressure transfer on the cup surface. Background technique [0002] After the mass production technology matured in the industrial society, various products gradually moved towards differentiated designs. Therefore, the demand for appearance design and personalized products came into being. Nowadays, various personalized products are sold in many different forms, such as It advertises that personal life photos are transferred to various products such as mugs, clothes, backpacks, stationery, etc., but the transfer quality still has a lot of room for improvement, especially the surface that receives the transferred items is not flat When it is a curved surface, such as a cup and other cylindrical objects, the tran...
