What is the difference between thermal transfer ink and sublimation ink?

Answer:

Sublimation thermal transfer is the use of disperse dye sublimation characteristics, that is printed on the transfer paper in the dye reaches the transfer temperature, the dye began to evaporate, and constantly penetrate into the fabric gap until the transfer of paper on the dye used or tend to use Finished, transfer paper on the residual dyes less, indicating the transfer on the fabric on the more, that is, the higher the saturation, the more colorful pattern, the more realistic. This is the quality of sublimation transfer paper quality As a core element.Because the thermal sublimation is the process of dye diffusion to the fabric, so sublimation pattern transfer does not change the original texture of the material, printing parts breathable, comfortable, feel and feel good, while the heat transfer is another Of a method: cotton or cotton with a high amount of fabric itself does not absorb the color, if the use of sublimation printing cotton, it is easy to wash away. In order not to be washed out, to use a dedicated thermosetting transfer paper.When the mug, the surface of the mug has been coated with a coating to absorb the color, but the coating can not be painted on the clothes, So it can only be coated on the transfer paper, so the printer is actually the pigment printed on the thermal transfer paper with the naked eye can not see the top of the coating, and then under high temperature and pressure, the actual transfer on the fabric is the coating And pigment mixture, rather than a simple pigment, so after the transfer has a hard feel, printing part of the airtight, transfer paper quality is directly on the thickness of the glial layer, the worse the quality, the greater the thickness , If the printing pattern area is large, as a measure of personalized costumes and functional comfort and beauty will no longer exist.
In fact, the best way to achieve pure cotton printing is digital direct injection, digital direct injection technology, the computer will be directly on the pattern of cotton fabric, to achieve WYSIWYG printing effect. Simple operation, completely break through the traditional screen printing on the color limit, digital printing can achieve 16.7 million color printing on the color, the color is extremely rich, because it does not use the intermediate carrier, so printed part of the breathable, comfortable, washed fastness 4 Level, repeated scrub does not fade. Due to the use of water-soluble supplies, does not contain any harmful to the human body chemical composition, it is environmentally friendly.
First of all, a concept: thermal transfer is divided into sublimation transfer and thermosetting transfer, sublimation transfer method is mainly used in chemical fiber fabrics and coated with thermal transfer coating of hard materials, the main application of heat transfer In cotton products. Although both are printed on the transfer paper and then in the high temperature and pressure under the fixed color, but there are essential differences, the use of digital printing and dyeing fabric printing ink for the sublimation of disperse dye ink, cotton fabric digital thermal transfer use Print ink is divided into reactive dye ink and acid dye ink, sublimation using sublimation transfer paper, thermosetting transfer using thermoset transfer paper, can not be used instead.
