Pearl Ink

Our organization have been offering Pearl Inks, which gives pearl like color and brightness. And our new product called STELLA ink is a new version of pearl ink, which can provide brighter and clearer color. It has a special standard color which can change color by view angle.
Today we explain about the color forming mechanism and special features of our Pearl inks and STELLA ink.
1. Mechanism of Pearl ink color forming
Surface layer of natural pearl is made of multiple alternating transparent layers of protein and calcium carbonate.
Incident light goes into the layers and refracts at the boundary faces of these layers. The reflected light at these faces interfere each other and provide the typical pearl color and gloss. Pearl pigment utilizes this principle. Multiple layers of low refraction factor materials (such as mica, SiO2 or Al2O3 etc.) and high refraction materials (metal oxides such as TiO2 or Fe2O3) will provide pearl color.

Special Features of STELLA Pearl pigment:-
1. Brighter color with less scattering of the light.
2. As the pigment diameter set in a shallow range, give better pearl gloss.
3. As the diameter of pigment is smaller than usual pearl ink (5-50 micron), can be printed with high mesh screen.
