The difference between thermal transfer and screen printing
1. Screen printing: When printing, the ink is transferred to the substrate through the mesh of the graphic part through the squeezing of the blade to form the same graphic as the original.
A. The screen-printed pattern is generally slightly raised relative to the medium and appears as a bubble. Therefore, over time, the pattern is often easy to peel off the paint.
B. Screen printing cannot filter all colors according to the picture, so the printed effect will have clear color boundaries. Among the two colors, it is difficult to reflect color filtering according to the picture itself;
C, silk screen printing is a single-color printing. Only one color can be printed at a time. Because the ink needs to be air-dried after printing, the production efficiency of large goods is very slow;
D. If you need to print a multi-color pattern, you need to set it several times. This may lead to inaccurate colors, stiff colors, and large deviations.
2. Thermal transfer: Thermal transfer printing uses high-resolution graphics and high-end imported electronic engraving systems, and uses the principle of thermal sublimation to transfer digital images to specially processed media. A, thermal transfer does not require plate making, printing, low production costs, rich profits, small investment, quick results;
B. Easy and fast operation, good pattern reduction effect, strong adhesion, can be used for on-site production
C, printed patterns are rich in layers, colorful, small color difference, good reproducibility, can meet the designer's requirements, and suitable for mass production of thermal transfer processing;
D. The thermal transfer process is extremely decorative and can greatly increase the added value of the product.
