Ink printing process is the material used to form the graphic information, which can be seen in the printing ink is about to play a decisive play, it will directly affect the printed image tone, color and sharpness. In print, we need to understand the composition of the ink and ink classification. Their wide range of physical properties vary, and some very thick, very sticky; while others are quite rare. Some vegetable oil as binders; some with a resin and a solvent or water as binders. These are based on the object that is printed substrates, printing method, print media type and drying methods to decide. Pigment as a main solid components of printing inks, it will play an important role, the relative density of printing inks, transparency, heat resistance, light resistance and resistance to chemical corrosion, etc., are concerned with the pigment. The role of pigment in the ink is obvious, its color determines the printing ink hue; its size determines the amount of ink concentration; its use to certain physical properties of the ink and consistency; its use under certain extent affect the printing ink drying, oxidation polymerization based printing ink drying was particularly prominent. Furthermore sticker printing, printing inks durability in all aspects is determined by the pigment. Since the printing ink varieties, different uses wine label printing, the pigment is also equipped with some differences, which requires printing should be based on product use, process characteristics adapted to the choice of ink, such as high-speed multi-color printing press packaging Products should be used in light, fast-curing ink abrasion resistance to ensure print quality. Cutter routine troubleshooting a photoelectric protection Tianjin production of full paper cutter malfunction, after emergency treatment machines still work, but because there is no protection detection, very worried about the safety of the operator, resulting in inefficiency . Remove the circuit board, visual inspection, we found that the substrate supply bridge rectifiers discoloration around Xie Gang sticker printing, concluded that the bridge pile has burned out, replace bridge rectifiers powered test, still no response. Measured with a multimeter wine label printing, new for the bridge pile has burned out, which determine the short-circuit part. Check one by one down from the bridge pile element and found a three-terminal regulator block (7805) is the breakdown, buy parts replacement, after the power supply circuit board bright lights. The operator of the circuit board attached to the machine, and in accordance with normal operating procedures, checking optical protection function is working, hands over light eyes, immediately stopped falling knife, tried several times, were normal. Failure thus excluded. Sticker printing through, beyond printing, sticker printing from Dongguan Xie Gang Chang Ping beyond packaging products factory provided.
