Organic pigment is the most basic material to provide color to the ink, but as the ink attached to the surface of the substrate, the color shown to the consumer often produces more or less deviations from the color of the pigment itself.

The reason is that in the ink, the pigment particles do not exist alone, but are dispersed in the connecting material medium. Microcosmic, the best wetting dispersion state of a pigment particle is completely evenly wrapped in a resin binder and attached to the surface of the substrate.The display of color is that the light incident on the coated pigment surface through the resin bonding material film layer is transmitted to the consumer through reflection. The transparency of the resin is good and bad, and the size of the color number directly affects the expression of different colors.

At the same time, whether the resin is sufficient for the wetting and dispersion of the pigment directly affects the uniform coating of the resin on the pigment, and also affects the color of the ink itself.
