The thermal transfer of roll sublimation paper is an emerging printing process, which has been introduced from abroad for more than 10 years. The process printing method is divided into two parts: transfer film printing and transfer processing. The transfer film printing adopts dot printing (resolution up to 300dpi), and the pattern is printed on the surface of the film in advance. The printed pattern has rich layers, bright colors, and ever-changing , The color difference is small, the reproducibility is good, it can meet the requirements of the designer, and it is suitable for mass production; the transfer process is processed by a heat transfer machine (heat and pressure) to transfer the exquisite pattern on the transfer film to the product On the surface, the ink layer and the product surface melt into one body after molding, which is vivid and beautiful, greatly improving the grade of the product. However, due to the high technical content of this process, many materials need to be imported.
Thermal transfer ink, dye ink, pigment ink, these three inks are not very different at the beginning. I did not get their principles very much. After contacting them for a long time, they will understand these three inks. Then let’s introduce these three inks. The difference!
Dye ink is a molecular-level fully soluble ink. This ink is a complete composite solution. The probability of blocking the ink head is very small. It is easy to be absorbed by the material after printing. The color is bright and the cost is low. The disadvantage is that it is not waterproof. Molecules decompose quickly under ultraviolet light, causing significant fading within one month of outdoor use under ultraviolet light.
tacky sublimation paper has the advantages of bright colors, clear layers and lower price than pigment inks, so it is the first choice for printing pictures and making color inkjet business cards.
