Differences Between Hot Stamping Ink And Heat Sublimation Ink

The coloring principle of printing is different, so the internal components of ink are different! There are two kinds of ink. One is pigment, the other is dye! Hot stamping uses paint! The coloring principle of the pigment is to use a synthetic resin that can generate a solid film and fix it on the surface of the fabric! Take personalized T-shirt hot stamping as an example. The reason why we use special transfer paper for T-shirts is that cotton fibers do not absorb color. On the image surface of the transfer paper, there is a layer of jelly, and the surface layer is coated with an ink absorbing coating so that a clear image can be printed. During transfer printing, on the one hand, the colloidal fabric under high temperature absorbs the color, on the other hand, it melts into the fiber gap of the cloth, and then firmly adheres to the fiber surface. The thermal sublimation ink belongs to the dye, which is a printing principle after the thermal sublimation principle of the ink is used for transfer printing and chemical reaction with the fabric; Because thermal sublimation does not change the surface structure of the fabric, the products after thermal sublimation have good sense and feel! So: the printing area of the hot stamping feels a little harder. If it is thermal sublimation printing, there is no obvious hardness difference between the printed part and the unprinted part! Finally, cotton garment printing, using pigments; Polyester materials and personalized products (such as metal plates, mouse pads, etc.) use dyes!
