As a high-brightness material to improve the added value of products, pearlescent materials are currently used in the printing industry with good effect, which can improve the brightness of product color, and can also change the color effect, which is a new material for packaging printing and color printing. So what are the pearlescent materials? Anmei mall for your analysis.
Pearlescent materials are mainly divided into the following categories:
1. Pearl powder
Pearlescent powder is divided into ordinary powder pearlescent materials and the use of soft resin dispersed pearlescent ball, the color is mainly silver, bright gold, metal color, rainbow interference color and chameleon series, etc., you found that the pearlescent powder and according to the direction of use and use effect have different particle size differentiation, the smaller the particle size, the stronger the pearlescent powder covering power; The larger the particle size, the stronger the gloss of the pearlescent powder; In the printing industry, the particle size has relatively strict requirements, small particle size can be used for offset printing, larger particle size can be used for flexo printing and gravure printing, and have better results.
2. Pearlescent paste
Pearlite paste is a high viscosity pearlite material, more suitable for mixing with offset printing ink, with excellent covering power and better gloss, suitable for offset printing.
In the use of pearlescent materials, there are the following methods:
1. In offset printing, pearlite powder with small particle size is mixed with printing ink in a certain proportion for printing; Or use water-based, UV glazing system to add a certain proportion of pearlite powder to the glazing oil for glazing coating, the effect is better; Mixing pearlite paste with offset printing ink in a certain proportion can greatly improve ink brightness and zhu effect;
2. Intaglio and flexo printing use pearlescent powder with the corresponding particle size of the printing plate and ink for mixing;
3. The pearlescent effect is related to the bearing capacity and mixing ratio of the ink to the pearlescent.
