Principle of thermal transfer printing

In fact, heat transfer technology is just a general term. There are many kinds of heat transfer technology. Today, I just introduce the principle of our 31 degree thermal transfer equipment. The heat transfer principle of 31 degree heat transfer equipment is called digital heat transfer printing. It uses the principle of thermal sublimation to transfer digital images, that is, photos, to the specially processed media. The whole process only takes a few minutes to finally print on a series of digital image products. The whole process only takes a few minutes, which is very suitable for on-site production. It can be used in all kinds of porcelain, metal, glass wood and other utensils and cloth to make any text and pattern you like. Because heat transfer printing does not need plate making or printing, it is easy to operate, quick and fast. It is widely used in many fields, with low production cost, high profit, small investment and quick effect. Therefore, it has a broad market prospect and high promotion Wide value. With the popularity of fashion handicrafts, a variety of transfer printing technologies for making handicrafts have also been developed, which has attracted many entrepreneurs and fashion beauty lovers. Among them, the most well-known transfer technology is water transfer and heat transfer. What is the heat transfer technology? What are its characteristics and uses? We will continue to discuss.

Transfer printing is a kind of printing method that transfers pictures and texts on intermediate carrier film to substrate by corresponding pressure. According to different pressure, transfer printing can be divided into water transfer, heat transfer, air transfer, screen transfer, low temperature transfer, etc. Among them, the thermal transfer printing is to print the portrait, landscape and other arbitrary images on the color ink-jet paper (or thermal sublimation ink-jet printing paper), or ordinary ink on the adhesive film heat transfer paper, and then heat the heat transfer equipment to a certain temperature within minutes, so as to transfer the vivid color of the patterns on the paper to porcelain, glass, metal and plastic A special printing process on materials such as cotton and cotton fabrics. It can be seen that the use of heat transfer technology, even for multi-color patterns, is only a process, so it can shorten the work of printing patterns and reduce the loss of materials (finished products) due to printing errors. In other words, the use of heat transfer film printing can be multi-color patterns into a map, no need to register, even if only a few simple equipment can also print realistic patterns, so that greatly improve its scope of application and achieve transfer operation. In other words, the 31 degree heat transfer equipment has low cost, good effect and broad market, which is worthy of independent entrepreneurship.

The heat transfer printing technology can be widely applied to porcelain, glass, metal, plastic, cotton textile and other materials, However, due to the limitation of heat transfer area and object shape, special tools are often needed for different areas and shapes of objects. Currently, the common heat transfer printing tools are mainly flat plate machine (hot stamping machine), baking plate machine, baking cup machine, etc., but after all, their production methods are based on the principle of heat transfer, so the production steps and flow The process is almost the same, but the application of heat transfer tools is different. The following is an example of using a tablet machine to transfer images to clothes to illustrate the steps and processes of heat transfer production.

Step 1: print the image through a color inkjet printer.

Step 2: put the printed pattern aside first, and then start to transfer. In transfer printing, when the printed image is placed on the clothes, the pattern should be face down, that is, reverse printing. Then adjust the time (usually 20 seconds) according to the transfer requirements of the heat transfer equipment, and close the heating plate of the equipment (Note: before the transfer of pure cotton T-shirt, a little darkening agent should be sprayed on the printing part, and the heat transfer should be carried out after air drying. The function is to change the ink color through the thermal pressure and improve the bright effect of the ink on the clothes).

The third step is to avoid heat transfer on the garment. After the time alarm of the heat transfer equipment, lift the heating plate, quickly uncover the pattern paper, take out the clothes, and turn off the power supply of the equipment.

Step 4: finally, when the temperature of the clothes becomes cool, fold and pack the clothes, the whole heat transfer printing can be completed and the finished products can be made.

Let's summarize the production process of digital heat transfer printing

The first step is to make high resolution pictures;

The second step is to print the pattern on the heat transfer paper through the heat transfer printer, several hundred meters per hour;

The third step. With the hot stamping machine and other common machinery can print the pattern to the commodity, the operation is simple, the pattern is formed at one time, and there is no need to register; one machine can print thousands of goods in 8 working hours a day! It can be used in ABS, PP, leather, mug and color changing cup
