Wholesale supply of high-efficiency Dongguan alcohol-free fountain solution, best dampening solution, dampening solution cherry blossom branches, green energy! In offset printing, plays a role in dampening solution is mainly reflected in three aspects: First, a blank part of the plate to form a film of water; the second is supplemented in the printing process damaged hydrophilic layer; third is to reduce the surface of the plate temperature. The alcohol in the dampening fluid also plays a role in three aspects: 1) is to reduce the surface tension of water, is conducive to water wetting spreadability on the PS plate; 2) is to accelerate the water spreading wetting rate, small molecule compounds for alcohol , diffusion speed; 3) is a volatile alcohol, to reduce the temperature of PS forum, condenses moisture in the air condenses on the plate surface. If there is no concept of the proposed environmental print, alcohol dampening solution may also be used for a long time, however, the current use of fountain solution in the alcohol component mainly isopropanol (Isopropanol, referred to as IPA) based, it is low boiling point, high volatile flammable organic solvents, harmful, in addition to alcohol also affects gloss inks, but also damage to rubber. More seriously, isopropyl alcohol emissions will pollute the environment. Therefore, the use of isopropyl alcohol, the environment, human, printing equipment and product quality are unfavorable, reducing its frequency of use or entirely without is an inevitable trend in printing. Wholesale supply of high-efficiency Dongguan alcohol-free fountain solution, best dampening solution, dampening solution cherry blossom branches, green energy! Customers are welcome to inquire! The following content has nothing to do with the product, can be ignored! For screen printing division of labor by the people together to complete, and only on the procedure for the next process is responsible, good self-check each step, self-inspection, quality control, customer satisfaction in order to produce halftone prints. The good match screen, inks and printing between the three is a prerequisite for good print. Printing quality directly determines the merits of printing quality, the quality of the printing plate just for testing, but in a stable printing quality of the premise, as typographer lightly, the same can not be the ideal print, but will result in greater waste or scrap of occurrence of defects. Before batch printing, printing should be fixed into the screen printing ink test, check the level of graphic layout copy, ink, ink thickness, size, registration accuracy. If the registration accuracy is poor, can be based on the framework of the previous tuning knob adjustment; if the ink hue is wrong, check whether the wrong ink and replace immediately; if bad inking available solvents to clean the graphic part of the plate, so that the ink through over performance and on the substrate wettability some improvement; if the order harmonic level graphics are quite different, they should immediately replace the print screen.
