First, there are two kinds of heat transfer printing, one is sublimation transfer, the other is heat set transfer!
Sublimation means that the printing paper is printed by offset or gravure printing presses with heat rising dispersed ink, and the pattern on the printing paper is transferred to the required medium (also known as heat transfer printing).
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 hard material,Thermoset transfer printing is mainly used in cotton products or dyed cloth.
The difference between the texture of the two printing methods is that the thermal sublimation pattern does not change the original texture of the material after printing, feel and look good.The thermosetting pattern (hot stamping) forms a layer of gelatinous material on the surface of the attachment after transfer, which has poor feel and is airtight.The two printing methods have their own advantages and disadvantages in production, and each has its own characteristics.
Digital thermal transfer printing is a new technology that combines digital printing technology with traditional sublimation thermal transfer printing to print graphic images in the form of plateless printing.It is characterized by the application of digital printing technology to print color patterns and images without plate making, saving the plate making process and cost, so it is suitable for the production of personalized products.
The technical characteristics of digital thermal transfer printing are that digital printing equipment uses special thermal transfer color printing ink and thermal transfer printing paper.
Compare advantages and disadvantages:
A, feel is
Digital direct printing is good, heat transfer flowers give a person the feeling of a word "hard".Of course, heat transfer with high quality paper feel will be slightly better, but it is still good digital printing.
Second, the colour and lustre
Thermal transfer color is definitely brighter than digital printing.Digital printing will have large color, gray and light, the solution is to use color ink combined with treatment liquid, can make the pigment more bright.But the heat transfer is more colorful.
Third, breathable
First, the question depends on the material of the receptor.For heat transfer printing, for pure cotton products are poor permeability of glue, non pure cotton does not have this kind of problem.Digital printing works better than cotton products.The effect of non-cotton is slightly worse, both have advantages and disadvantages!
