The introduction of water transfer printing materials1

Water transfer printing materials refers to the substrate surface processing to transfer whole graphic printing film, base material can be a plastic film, also can be water transfer printing paper. The emergence of the printing film as graphic carrier, it should be a big step forward in printing technology, because there are a lot of product is difficult to direct printing, and with this carrier, people can through the mature printing technology to graphic on the carrier of easy printing first, then transfer graphic on the substrates. Such as have a certain height, more heavy, grotesque items or area is very small things can use transfer printing process. Single for water transfer printing technology, its adaptability is very wide, almost no can transfer printing products, widely used in water transfer printing transfer printing materials have only the water transfer printing film. < br / > < br / > only the water transfer printing film production process is similar to that of a thermal transfer film, only the water transfer printing membrane is made of gravure printing with traditional printing process, in the water soluble pva film surface printing. Only the water transfer printing film base material expansion rate is very high, it is easy to closely attached to an object's surface, that is it suitable for the whole object surface is the main reason for the transfer. But the scalability big shortcoming is also obvious that in the process of printing and transfer printing, film on the surface of the graphic easy to deformation; If process followed by heat transfer processes is not good, thin film are likely to rupture. In order to avoid this shortcoming, we often only the water transfer printing membrane on the graphic design to do not have specific modelling, also does not affect viewing repeating patterns after deformation. Water transfer printing film on the gravure printing printing can obtain a high elongation, can greatly reduce the printing cost, at the same time, gravure printing has precise tension automatic control system, a can print out 4 ~ 8 kinds of color, overprint accuracy is higher. Gravure water not only use the water transfer printing ink printing film, compared to traditional ink, water transfer printing ink good resistance to water, drying methods for volatile dry < br / > < br / >
