Pearlescent pigments having a cross section similar to the physical structure of the pearl; low optical index of the core is mica, wrapped in the outer layer is a high refractive index metal oxide, such as titanium dioxide or iron oxide. In an ideal situation the application, pearlescent pigment uniformly dispersed in the coating in high quality color pearl powder, and parallel to the surface of the material to form a multilayer pearl pink color distribution, the same as in the pearl, the incident light through multiple reflections, reflected interference at Pearl effect. Gravure main low viscosity liquid ink. Deployment of pearlescent pigments should choose a higher transparency of the link material (resin) and printability good transparency diluent. In the preparation of the color ink, to use different colored inks based on different types of paper. White card, white paper should be used in pigment color pigment domestic pearl powder, PET composite paper should be used in dye pigments. Pigment and pearl powder can be mixed, generally no more than 20% of pearl powder. As overweight will affect the tone pearl effect, because only in the light of abundant pearl pigment ink layer in order to have a special optical interference function, and excessive use of other colored pearlescent pigments cause a lot of light is lost.
