Classification and characteristics of thermal transfer

Views:875Time:2021-09-09
Thermal transfer is an emerging printing process, which has been introduced from abroad for more than 10 years. This process printing method is divided into two parts: transfer film printing and transfer processing. The transfer film printing adopts halftone printing (resolution up to 300dpi), and the pattern is printed on the surface of the film in advance. The printed pattern has rich layers, bright colors, and ever-changing. , The color difference is small, the reproducibility is good, and it can meet the requirements of the designer, and it is suitable for mass production.
The transfer process transfers the exquisite pattern on the transfer film to the surface of the product through a heat transfer machine (heating and pressure). After forming, the ink layer and the surface of the product are integrated, which is vivid and beautiful, which greatly improves the quality of the product. However, due to the high technical content of this process, many materials need to be imported.
Thermal transfer is divided into thermal transfer (suitable for a large number of printing methods) and digital thermal transfer (suitable for small quantities, make your own special products)
The difference between the two production processes:
Thermal transfer production process:
The first step. Make high-resolution pictures;
The second step. According to the size of the picture, make a dot-type intaglio electro-engraving plate;
The third step. Install the intaglio plate on the printing machine and print it on the PET polyester film to print it into a thermal transfer film, which can print thousands of meters of finished patterns in one hour.
The fourth step. Install the thermal transfer film on the thermal transfer hot stamping machine for printing. The operation is simple, and the pattern is formed at one time without color registration.
A thermal transfer hot stamping machine can print tens of thousands of products in 8 working hours a day.
It can be applied to ABS, PE, PP, EVA, leather, stainless steel, glass, wood, and coated metal.
Digital heat transfer production process:
The first step. Make high-resolution pictures;
The second step. Print the pattern on the thermal transfer paper through the thermal transfer printer, hundreds of meters in an hour;
The third step. Use hot stamping machine and other ordinary machinery to print the pattern on the product, the operation is simple, the pattern is formed at one time, no color registration is required;
One machine can print thousands of products in 8 working hours a day.
Can be applied to ABS, PP, leather, ceramic coated cups
Why choose thermal transfer for large quantities? Should I choose digital thermal transfer if the quantity is small?
Because thermal transfer requires the production of electric engraving, while digital thermal transfer does not require the production of electric engraving. In contrast, the cost of thermal transfer is relatively high, but why do people choose thermal transfer when the quantity is large? In addition to quality issues, the most important issue is productivity. Thermal transfer can print thousands of products in one hour. , But digital thermal transfer can only print about a hundred products in one hour. So if it is just making some commemorative gifts, people will choose digital heat transfer, but if the manufacturer needs to print, they will choose heat transfer.
Features:
1. The pictures are exquisite, which can be completed with ordinary hot stamping machine and thermal transfer machine.
2. The application of inktrk thermal transfer ink does not require coloring, and the pattern is formed at one time without color registration.
3. With C-AW thermal transfer paper, you only need to print it out, with simple operation, exquisite printing work and low production cost.
4. Small product loss, high added value, and strong decorative craftsmanship.
5. High covering power and strong adhesion.
6. Comply with green printing standards, no environmental pollution.
