tinctorial strength
also called Tinting intensity 。
finger Pigment As Colorant When in use, use its own color to make Colorant have colour Ability. Coloring power not only depends on pigments Chemical structure It is also related to a variety of influencing factors, such as Particle size Small (0.05~0.1 μ m), even distribution, can show high coloring force; But the particles are too thin, transparency Increase, Covering power Lower. Coloring power is usually measured by Standard sample For comparison, it is determined by the difference ratio, expressed as a percentage. It can also be used instrument Color measurement method: quantitative measurement. express printing ink The difference in color concentration between the sample and the standard sample. Sometimes, in order to distinguish between white pigments and colored pigments, the coloring ability of colored pigments is simply called coloring power, and the coloring ability of white pigments is called achromatic power.
The ability of a white pigment to lighten the color of another pigment when mixed with another pigment is called achromatism.
