Technical characteristics of rotary screen printing
1. Appreciation of products
In general, an ink layer with a thickness of about 70 microns is enough to stimulate people's sense of touch. Tactile effects can be used to enhance the influence of a brand's characteristics, such as: Procter & Gamble products-Rejoice logo (logo), L'Oreal logo and so on. The thick ink layer produced by the rotary screen is unique in that it is difficult for other products to achieve and is favored by high-end brands.
Using screen printing for local glazing, compared with the surrounding printing effect, the glazing pattern is bright, bright and three-dimensional. Because of the thick screen printing ink layer, it will bulge after curing, and it looks like an indentation. Screen printing glazing is stronger than offset printing glazing in terms of height, leveling and thickness, so it has always been favored by users and manufacturers.
2. High speed and high quality
The main difference between rotary screen printing and other printing methods is high speed, integration with other printing methods, one-time die-cut forming, more efficient and faster.
Other factors that should be paid attention to during the rotary screen printing process
1. Most of the inks used for rotary screen printing are UV-curable inks, which are cured by UV light sources, but there are also inks that are dried by hot air. For example, the conductive silver ink used for printing the "antenna" of RFID electronic tags is solvent-based ink. , Which uses the hot air drying method.
2. Due to high speed operation, the viscosity and leveling of the ink are different from other flat screen printing.
3. When printing special products, such as optical variable ink and pearlescent ink, the ink particles corresponding to the equipment should be correctly selected.
