Transfer printing film, transfer printing device and transfer printing method

Abstract

The invention discloses a transfer printing film, a transfer printing device and a transfer printing method. The transfer printing film comprises a diaphragm and a transfer printing resin layer. One side of the diaphragm has a concave-convex surface. The transfer printing resin layer covers the diaphragm. One side of the transfer printing resin layer opposite to the diaphragm has a stereo pattern matched with the concave-convex surface. The transfer printing film can be repeatedly used.

Description

technical field [0001] The invention relates to a transfer film, especially a reusable transfer film. Background technique [0002] With the development of technology, consumers have increasingly higher requirements on the appearance of high-tech products such as mobile phones or notebook computers. For example, consumers will expect products to display fashion and special aesthetics. In order to meet such demands, it is necessary to emboss different patterns on the shell of the product. [0003] Generally speaking, the semi-finished product of the shell is fed into the mold, and the semi-finished product is embossed by the pattern of the mold. However, if the pattern of the shell is to be changed, a different mold needs to be redesigned. Due to the cost of redesigning the mold, the production cost of the product is greatly increased. [0004] On the other hand, there is also a method of using In-Mold Decoration (IMD) technology to decorate the appearance of the product....
