The distance the squeegee contacts the plate. The reduction of the distance between the blade and the printing plate is beneficial to increase the ink transfer rate, but it is easy to produce a dirty plate; otherwise, it can effectively solve the dirty plate and avoid some small line marks, but it will reduce the ink transfer rate. The flatness and warpage mainly depend on the method of installation. Of course, it may also be related to the sticking of foreign objects on the blade or the lining. This article will introduce you to the ceramic squeegee.
Such periodic fluctuations not only have a certain influence on the plate roller base, but also the effect on the doctor blade is very obvious. The long time vibration will make the doctor blade scrape dirty, resulting in dirty version. A phenomenon occurs. By increasing the pressure on the doctor blade pressure, the problem can be solved in a short period of time, but the problem cannot be solved fundamentally, and it also has a significant impact on the service life of the doctor blade.
The polishing quality of the surface of the plate roller is mainly manifested by the number of burrs around the cell. The good quality plate has a clean, no burr, and the cells are clear and there are no impurities inside. This ensures that the plate roller does not damage the doctor blade during the printing process. After the squeegee is frequently replaced, if there is still a ruled line on the printed product, it can be generally determined that there is a problem of polishing quality of the plate roll.
Solvents are often used to adjust the viscosity and dryness of the ink during the printing process. In actual operation, the solubility should be as strong as possible. A solvent that evaporates quickly, such as ethyl acetate, isopropanol, and the like. Different types of inks should use different types of solvents. If the solvent is used improperly, the ink is not dissolved sufficiently and sticks together. Once adhered to the doctor blade, a cut line is formed.

Red Light Therapy has been widely used in traditional clinical medicine, and the effect is remarkable. Medical-grade red light accelerates wound healing, reduces pain and inflammation, and stimulates collagen production anti aging. With the development of medicine and in-depth research, it has been proved that red light therapy in a specific band can be used to improve vision, and the color vision of the subjects improved by 20%.
