First, the basic knowledge of heat transfer printing
Heat transfer printing is a new process printing method.Began to be in China started around 2001, generally divided into two most printing and transfer printing film processing, printing printing film using network printing resolution (300 dpi), will design printed on thin film surface in advance, printing the design level of rich, colourful, go, small chromatism, good reproducibility, can meet the requirements of design patterns is effect, and is suitable for mass production;Transfer processing through the heat transfer machine processing (heating and pressurizing) transfer the beautiful pattern on the transfer film on the surface of the product, after forming the ink layer and the surface of the product into one, lifelike and beautiful, greatly improve the level of the product.However, due to the high technical content of the process, many materials need to be imported.
Ii. Heat transfer process
(1) make high-resolution pictures;
(2) according to the size of the picture to make a netted gravure engraving;
(3) the gravure installation on the printing machine printed on PET polyester film is printed into thermal transfer printing flower film, one hour can print thousands of meters of finished patterns;
(4) the heat transfer printing flower film installation on the heat transfer printing machine for printing, simple operation, pattern molding, no need to register.
Iii. Application scope of heat transfer printing:
Heat transfer printing process is applied to all kinds of ABS, PP, plastic, wood, coated metal and other surface products.We can design and produce heat transfer film according to customers' requirements, and transfer the pattern to the surface of the workpiece through heat pressing to improve the product grade.Heat transfer printing technology is widely used in plastic, cosmetics, toys, electrical appliances, building materials, gifts, food packaging, stationery and other industries.
