Pigment moisture content on the silk screen ink have any effect
Additional materials are some of the materials that are added in the manufacture of ink, as well as in printing use, to improve the performance of the ink itself. According to the basic composition of the preparation of the ink, in some characteristics still can not meet the requirements, or because of changes in conditions, and can not meet the requirements of the use of printing, you must add a small amount of auxiliary materials to solve.
The filler is white, transparent, translucent or inappropriately powdered.
