The ink on the printing china industry is very important, how to choose the ink, to determine the quality of products, following to analyze how to select the ink!
1. Gloss either measured by the instrument can also judge with the naked eye naked eye observation, usually in color matching process. The gloss actually refers to the degree of the size of the ink printed sample irradiated by light, the ability to reflect light in the same direction. Its direct impact on print appearance, is a very important indicator. At the same time, the choice of ink to distinguish the ink itself is light, semi-gloss or matte ink, avoid mixing errors.
2. Hue is the basic color, for a qualitative difference. Color, we must first consider hue is consistent detection methods usually through scratch like paper scraping color or analog printing standard sample and the sample were observed with the human eye comparison.
3. Hiding power of ink to cover the extent of their background. Hiding power, the better the transparency of the worse, the transparency level of ink chromatic efficiency and the extent of the impact of the printing substrate. especially in book printing.
4. Tinting strength is a the ink concentration level of a method. The measurement is then compared with the standard sample, a certain amount of ink is further added a certain number of standard white ink dilute mixed. Difference reflects the color force strength of the ink blending the extent, affect the printed ink film thickness.
