In actual color matching, the coloring pigments used cannot be extremely pure three primary colors, and it is unlikely to be exactly the desired pure color, usually with some similar hues more or less, to achieve For a given color sample, it is always necessary to use a variety of coloring pigments to match. This requires our coloring technicians to have a considerable understanding of the hue and shade of various pigments.
In the color matching, it is necessary to carefully distinguish the hue and light of various toner raw materials, such as the red series has yellowish red and bluish red (with purple light); the blue series has cyan (green light blue) and red light blue, There are transparent and opaque; the yellow series has reddish and greenish yellow (greenish yellow); purple has red and blue (that is, reddish purple and bluish purple); orange has orange-red and orange-yellow ; Green also has bluish green and yellowish green raw materials; fluorescent red series has reddish, yellowish, and purple; fluorescent yellow has greenish such as fluorescent lemon yellow, and yellowish such as fluorescent yellow 3G; According to the tinting strength of various toners, various toner materials of different concentrations and shades are presented.
When selecting the toner, it is necessary to match the applicable resin raw materials according to various characteristics of the toner, such as temperature resistance, dispersibility, hue, tinting strength, transparency (hiding power) and other indicators. In short, it must meet customer requirements. Then, according to the color matching skills and the principle of color matching, the combination and matching of toners are carried out, and we strive to use low-cost formulas to prepare qualified colors, and all aspects can meet the requirements of customers.
