The digital direct print is like a printer printing documents, and thermal transfer is like a fake tattoo sold on the street.
One, concept: There are two types of printing, one is sublimation transfer, another is thermal solid transfer way!
Sublimation refers to the process of printing the pattern on the printing paper to the medium (also known as heat transfer printing) after the printing paper is printed on offset or intaglio printing ink with thermal lift dispersing.
Thermosetting transfer way (often said pyrograph) refers to the use thermosetting ink through again with silk screen printing and offset printing design into the film, printing film on the heat transfer patterns to t-shirts, school bags, and clothing products.
Such as two kinds of printing way have obvious differences in application, sublimation transfer printing method is mainly used in chemical fiber cloth, textile fiber and coated with thermal transfer coating on the hard material of thermosetting transfer methods mainly used in pure cotton products or dyed fabrics.
The difference between the two printing patterns in texture is that the thermal sublimation pattern does not change the original texture of the material, which has a good feel and appearance. The hot solid pattern (permanent painting) forms a layer of glue on the surface of the attached object after transfer.
Two, the two printing methods have their own characteristics and advantages in production:
The digital thermal transfer is a new technology based on the traditional sublimation thermal transfer, which combines digital printing technology to print an image without block printing. It is characterized by the use of digital printing technology to print color patterns and images do not need platemaking, saving the platemaking process and cost, so it is suitable for the production of personalized products. Digital thermal transfer technology features digital printing equipment using special thermal transfer color printing ink and thermal transfer printing paper.
Compare the advantages and disadvantages:
First, feel digital straight printing good, heat transfer printing flowers to people feel on a word “hard”. Of course heat transfer printing with a good quality paper feel slightly better, but still digital printing good.
Second, color heat transfer printing color is absolutely more vivid than digital printing. Digital printing can be large, gray and light. The solution is to use color ink combined with processing fluid to make the pigment more colorful. But the heat transfer is more vivid. At first, the problem depends on the material of the receptor. For heat transfer printing, for pure cotton products are adhesive permeability is poor, non-pure cotton does not have such problems. Digital printing works better than cotton. Non – cotton effect slightly poor, both advantages and disadvantages!
