What should I pay attention to when applying pearl pigment powder to printing ink?

We should notice the following when using pearl pigment powder:

1. We can use pearl pigment powder with transparent dye or pigment to get unique and beautiful color effect. But when used with less transparent pigment, it will lose some pearly luster.
2. High-shear stirring or prolonged mixing can damage the particles of pearl pigment powder, which therefore will have less pearly luster.
3. When ink or coating has low viscosity, pearl pigment powder particles will precipitate. Please stir again before use.
4. Due to the phenomenon of complementary colors, please do not mix rainbow-series pearlescent products.
5. To realize even dispersion, please wet the pearl pigment powder in advance separately, then with major additives and solvents, and then mix them for use.
