Heat transfer printing refers to the use of hot press to transfer heat transfer hot stamping or lettering
film to the surface of the workpiece. At present, there are many products using heat transfer printing
and hot stamping on the market. In addition to the common clothing, shoes and hats, there are also
bowls and plates, buildings, promotional materials, cars, various models, etc，What is the principle
of heat transfer printing?
Basic principle: first, print the pattern on the pet film coated with release agent. After drying, use this
patterned film to iron to the surface of clothes or other fabrics under high temperature and high pressure,
leaving the pattern, tear off the waste film, and complete the hot stamping process Therefore, this method
is called "hot stamping", also called "heat transfer hot stamping".
The feature of heat transfer printing and hot stamping is that the printing materials will not vaporize like
sublimation dyes. This printing material will not cause the slurry to penetrate into the fabric fibers due to
high pressure and temperature. Although the same can be pressed with a transfer machine, the "printed"
surface of the clothes will be attached to the surface of the clothes like a film.
If you want to understand the heat transfer printing and hot stamping, you need to know its base material
first. Most of the base material for heat transfer printing and hot stamping is made of PET material. After all
colors are printed on the PET sheet, you also need to apply hot melt adhesive on the back of the pattern. It is
precisely because of this hot melt adhesive that you can lock the clothes with the pattern firmly. After you tear
off the waste PET film, you can finish the transfer process.
The advantages and disadvantages of heat transfer printing and hot stamping are also obvious. The disadvantage
is that if the pattern is larger, it will be less breathable on the clothes, and the feel is not as soft as heat sublimation.
The advantage is that the pattern level is full, the color is beautiful, and the cost of plate making is low.
