High purity spherical silica for the company ink, with good flow and lubrication, can achieve better suspension and dispersion stability, pigment but with less hiding power, gloss, resin, fine particle size, a continuous film , uniform Guanghao, thin film, the printing of the image is clear, if used in UV ink, may lead to faster cure speed, and because of the fine filler dispersed ink film shrinkage to eliminate wrinkles. In the glass ceramic ink, if the inorganic nano-scale materials constitute the fineness, it will save a lot of raw materials and more delicate designs printed, silica powder filler with exceptional results, which will glow brightly colored ink. 
 Since silica UV light showed a strong catalytic properties, the use of ultra-fine silica powder as filler of ink, the light fastness grades 2-3 generally increased, ink film wear resistance, heat resistance and adhesion to both improved significantly. In print (especially high-end color printing), the product quality and fineness of ink, the purity of a great relationship. Only a small fineness, high purity of the ink to print high-quality prints. Refers to the fineness of ink pigment ink (including filler) particle size and pigment, filler, compound distribution uniformity in the link. Technology Practice of the situation showed that the color printing products, printing, or on the ground with textured pages contain small negative word, Yinxian prone to paste printing process from the dirty version of the quality of failure, the face of it, may think that consistency is not an ink viscosity is too large , cloth, ink is too big or too much pressure, and other reasons, the real reason is that the ink particles are too thick cause. Fineness of ink and pigments, fillers, the nature and size of the particles have a direct relationship. In general, the use of inorganic pigments (not including carbon black) ink made of fineness is not good, relatively coarse particles more, which is ink rolling process has a great relationship. Ink in the process of rolling process the more the number of grinding, it becomes more uniform, pigment particles and the greater the contact surface of binders, the finer particles of ink, the printing performance will become better, more stable. Obviously, the fineness of ink and print quality are closely related, such as the printed version netted for example, pages of high-profile and middle tones 1 to 4 as there is no shortage of outlets, and if the ink particles and electronics area ratio is closer to , then the empty network or spread easily fluff, or even electronic printing defects do not clean, so the fineness of the better ink, printed on the net are, the more clear and full and powerful.
