Because screen printing has the characteristics of missing printing, it can use a variety of inks and coatings, not only can use pastes, adhesives and various pigments, but also coarser particles. In addition, the screen printing ink formulation method is simple, for example, the light-resistant pigment can be directly put into the ink for formulation, which is another major feature of screen printing. Screen printing products have a great advantage of strong light resistance. Practice has shown that according to the maximum density value range measured after using black ink on coated paper for one impression, the offset printing is 1.4, embossing is 1.6, gravure printing is 1.8, and the maximum density value range of screen printing can be Up to 2.0, so the light resistance of screen printing products is stronger than that of other types of printing products, and it is more suitable for outdoor advertising and signage.
Generally, the maximum size of the area printed by printing methods such as offset printing and embossing is the full-sheet size, and if it exceeds the full-sheet size, it is restricted by mechanical equipment. While screen printing can print large areas, today’s screen printing products can reach a maximum range of 3 meters × 4 meters, or even larger.
