Pearlescent materials, as a high-brightness material for increasing the added value of products, are currently used in the printing industry. They can improve the vividness of the color of the products, and can also change the color rendering effect. They are new materials for packaging, printing, and color printing. What about pearlescent materials? Anmei Mall analyzes for you.
Pearlescent materials are mainly divided into the following categories:
1. Pearl powder pearl powder is divided into ordinary powdered pearl material and pearl ball with soft resin dispersion. The colors are mainly silver, bright gold, metallic, rainbow interference color and chameleon series. Your sister mall found pearl powder in it. According to the direction of use and use of different particle sizes, the smaller the particle size, the stronger the hiding power of pearl powder; the larger the particle size, the stronger the gloss of pearl powder; The diameter can be used for offset printing, larger sizes can be used for flexo and gravure, and have a better effect.
2. Pearlescent Pulp Pearlescent Pulp is a kind of high viscosity viscous pearlescent material, which is more suitable for mixing with offset printing ink. It has excellent hiding power and good gloss and is suitable for offset printing.
In the use of pearlescent materials, there are the following methods:
1. In offset printing, pearlite powder with smaller particle size is selected and mixed with printing ink in a certain proportion, and then printed; or water-based, UV polishing system is used to add a certain proportion of pearl powder to polishing coating oil. Coating, the effect is better; pearl pulp and offset printing ink mixed by a certain ratio printing can greatly improve the ink brightness and Zhu Guang effect;
2. Intaglio printing and flexographic printing use the pearl powder with the corresponding particle size of the printing plate and the ink to be mixed;
3. The pearlescent effect is related to the bearing capacity and mixing ratio of the pearl ink.
