How to judge the quality of thermal transfer printing film?

The pattern of the heat transfer printing film is determined by the electroengraving plate and the ink color. We know that the pattern is printed by the electroengraving plate through the ink, so the depth of the electroengraving plate also has a great influence on the color effect. Secondly, there is no absolute value for ink mixing. It all depends on the experience of the colorist. Of course, the exception is partial color, which can be directly mixed by the ink factory.

 Another important point is the environmental protection of inks. Environmentally friendly printing is now advocated, and most products require environmental testing. The degree of fusion between the heat transfer film pattern and the material used for hot stamping mainly depends on the matching value of the release agent and glue of the heat transfer film and the material. The simple understanding is that the pattern is easier to detach and has good adhesion after hot stamping. The glue used for hot stamping each type of heat transfer film is different for different materials.

 The storage time is related to the carrier, glue, release type, and ink. Generally, the heat transfer film that can be hot stamped normally after being left at room temperature for half a year is very stable. Thermal transfer printing is a new type of printing technology that was introduced from abroad more than 20 years ago. Thermal transfer printing is suitable for hundreds of materials. It can be said that it is widely used. It is currently used in many industries. A kind of thermal transfer printing processing, thermal transfer printing processing is a very developing industry. Thermal transfer is a way to print patterns from the transfer film onto other media by applying high temperature and high pressure to the transfer film.

Thermal transfer printing is a new way to print patterns on other materials that you want to print. thermal transfer printing processing is especially suitable for producing small quantities and personalized products. It can also print photos or For some colorful patterns, the principle of thermal transfer processing is to use a certain technique to print the required pattern on professional transfer paper, and then use high temperature to print the pattern on the transfer paper to the area that needs to be printed. pattern above.

Thermal transfer printing process is applied to the surfaces of various ABS, PP, plastic, wood, coated metal and other products. Thermal transfer film can be designed and produced according to customer requirements, and the pattern can be transferred to the surface of the workpiece through hot pressing to improve product quality. Thermal transfer printing process is widely used in plastics, cosmetics, toys, electrical appliances, building materials, gifts, food packaging, stationery and other industries. The equipment used in the thermal transfer process includes Imaging King heat transfer machines: including cup baking machines, cap baking machines, baking pan machines, flat heat transfer machines, flatbed machines, shaking head heat transfer machines, etc. The required consumables include professional heat transfer machines. Transfer paper and thermal transfer ink, plus a printer, computer, and digital camera are all you need to complete the thermal transfer process.

Different materials have different transfer effects. There are two main types of thermal transfer, one is film transfer and the other is sublimation transfer. The reason why it is called film transfer is because there is some colloid on the transfer paper. The colloid pattern is transferred to other media materials by heating. The pattern transferred by using good materials is very thin, beautiful and durable. , if poor materials are used, the transferred pattern will be easily damaged and have a certain degree of stickiness, and the transferred pattern will be thicker and less beautiful.
