The quality of the coated paper is good or not, in addition to the quality of the base paper has a great impact, the composition of the coating is also a very important factor, when the coating adds different types of organic pigments to replace the most commonly used white pigment - white soil, the coated paper manufactured in whiteness, white paper gloss, printing gloss, opacity, smoothness, and so on. Such aspects are proportional to the amount of organic pigments added, which means that organic pigments can improve the properties of the paper after coating.

  When different types of organic pigments are added to the coating to replace titanium dioxide with high price, high whiteness and high refraction coefficient, the coated paper produced in terms of white paper gloss, printing gloss and smoothness is proportional to the amount of organic pigments added, but in terms of whiteness and opacity, it is inversely proportional to the amount of organic pigments added, which means that in some special uses, Although organic pigments cannot completely replace titanium dioxide, they can still make the properties of coated paper maintain a certain level without too much difference.

  When different types of organic pigments are added to the coating to replace the cheap, commonly used white pigment - calcium carbonate, the coated paper produced in whiteness, white paper gloss, printing gloss, opacity, smoothness, etc., is proportional to the amount of organic pigments added, which means that if you want to further improve the nature of the coated paper, the use of organic pigments is an inevitable trend.

  In terms of the relationship between the amount of coating and the quality of coated paper, when organic pigments are added to the coating, the properties of coated paper are better than those without organic pigments, and when the properties of the coated paper are close, the amount of coated paper with organic pigments can be reduced. When the organic pigment is dense, the coating amount can be reduced by about 30%, while the organic pigment can be reduced by about 40%, and if the organic pigment is hollow, the coating amount can even be reduced by about 45%, which means that in the trend of lightweight paper, organic pigments can bring considerable help.

  The quality of printed matter has a great relationship with the printed material, and the quality of the printed material is closely related to the base paper, paint and surface treatment, therefore, choosing a good paper as the printed material is a cost saving and improving the quality of printed matter.
