How to Select the Right Pearlescent Pigment

Pearlescent pigments have the ability to change optical effects from bright and bright to soft and elegant. This special effect depends on the selection of pearlescent pigments and media. Each series of pearlescent pigments has different brightness, different particle sizes and special color effects. However, the effect of pearlescent pigments will be affected by the media. Transparent media can maximize the colorful pigments. When pearlescent pigments are mixed with media with poor transparency, the pearlescent effect will be greatly affected.
When pearlescent pigment is mixed with other colorants, dyes or pigments with good transparency shall be selected.
Printing can be divided into lithographic printing, flexographic printing, intaglio printing, screen printing and thermal relief printing. The application of pearlescent pigments in different printing methods is different.
The main factors affecting the pearlescent effect of printed matter are: the nature of ink, the transfer mode of ink, the printing process and the type of substrate.
The particles of pearlescent pigments are larger than those of traditional ink pigments, so some printing conditions must be adjusted to ensure printing quality. The number of lines (lines) on the transfer and gravure rollers should be revised to 75-100 lines (lines), and the screen should be at 100 meshes and 250 meshes, so as to match the use of larger particles, which also makes the ink film thicker. Therefore, the drying temperature should be adjusted, and the smoothness of the paper should be noted. Volatility of solvent and developer.
When the printing surface is calendered or embossed, the effect of pearl luster will be improved.
The gift wrapping paper with special effect can be produced after being printed by dark paper and embossed. The unbleached natural kraft paper can produce metallic luster after being printed and calendered.
