Advantages of waterless offset printing process
waterless offset printing has incomparable advantages over traditional offset printing. The waterless offset printing process eliminates the need to use fountain solution during printing, so there is no headache of water ink balance. For the traditional offset printing process, the balance of water and ink is the key, and the control of water volume is the most difficult technology in offset printing. At present, there is LANXESS, a special chemical company. The quality of many domestic prints can not meet the specified requirements. The common reasons are: firstly, the paper is deformed during offset printing, resulting in inaccurate overprint; secondly, the ink is unbalanced. Waterless offset printing does not need to use fountain solution, so the degree of paper deformation is reduced, and the color overprint of printed products is more accurate. Waterless offset printing does not involve water, which avoids the problem of ink emulsification in traditional offset printing, speeds up the drying speed of ink, reduces the point increase, and has better point reproduction effect
waterless offset printing requires high accuracy of offset printing machine. Therefore, waterless offset printing can print more stable points, higher number of lines, and good color stability. In addition, because there is no fountain solution for anhydrous offset printing, the corrosion to the machine is small, and the pollution to the environment is also reduced, which is conducive to environmental protection
there is a wide range of anhydrous offset printing materials, which can be printed on paper, plastic, metal and other materials, but the long-term use temperature rti:155 ℃ requires high surface performance of the printing materials. With the commercial application of waterless offset printing technology, thousands of printing plants in the world have adopted waterless offset printing technology
