Method for printing transfer printing film and forming pattern on printing stock

Abstract

The invention discloses a method of forming pattern on a printing stock by using a printing and transferring membrane. The printing and transferring membrane comprises a transferring carrier membrane (1), a mold releasing layer (2), a thermal fusion welding layer (5) and a printable layer (6). The method is carried out as follows: adopting the required transferring pattern designed by computer, printing the pattern onto the printing and transferring membrane, using a carving machine to cut along the edge of the pattern, removing the remaining parts of the transferring membrane, obtaining the transferring membrane with the required transferring pattern shape, using the adhesive sticker membrane with high-temperature resistance to separate the transferring pattern from the mold releasing layer (2) of the printing and transferring membrane, finally enabling the thermal fusion welding layer (5) to be tightly close to the printing stock, then forming the required transferring pattern on the printing stock by heating and pressurizing.

Description

Technical field [0001] The invention relates to a method for forming a pattern on a substrate by a printing transfer film. Background technique [0002] The transfer of textiles and leather is to print the images and texts on the textiles or leather by hot pressing a transfer film with images and texts and a hot melt adhesive layer printed in advance. This transfer film is composed of a transfer carrier film, a release layer, a color layer and a hot melt adhesive layer. The transfer carrier film can be PET, OPP or paper, etc. The color layer can be screen printing, offset printing or gravure printing. To be done. A background layer is generally provided between the hot-melt adhesive layer and the color layer. This layer is generally silk-screened, and a small part of the leather transfer is completed by gravure printing. Because the offset printing is very thin, the ink is transparent, the hiding power is poor, there must be a background layer; silk screen and gravure printing sh...

AI Technical Summary

Problems solved by technology

The above-mentioned production method has many procedures, and it is difficult for workers to control the operation. The most important thing is to make a plate when printing the color layer. Silk screen printing needs to use a silk screen printing plate, gravure printing needs to make a gravure printing plate, offset printing needs to make a PS plate, and it also involves negatives. In this way, it is difficult to bear the small order quantity, and the personalized production cannot be realized, and the technical requirements and equipment requirements for the transfer film manufacturers are high.
