Wholesale Ink Scraper Overview Squeegee for Printing Machine is a tool to control ink transfer in offset printing. In gravure printing, the ink scraper is a mechanical operation, which is relatively simple, but it has its own characteristics. The ink scraper is a sheet used to scrape off the excess ink on the surface of the cylinder on the printing press. It is divided into two types: metal and non-metal. The ink scraper is responsible for scraping off the ink in the non-patterned area during each printing process. Specification Material: Carbon steel, plastic, coating, stainless steel, etc. Scope of application: General packaging printing, cardboard and decorative printing, gravure printing film aluminum foil, flexible printing. Features 鈼?/strong> The sharpness of the squeegee for printing machine depends on whether it is a new knife, the angle of the blade when sharpening the knife, and the type of sandpaper (whetstone) used. The appropriate sharpness of the knife should be able to scrape the ink cleanly without generating knife lines, while a scraper that is too sharp is likely to produce line marks and wear the printing plate at the same time. 鈼?Factors affecting the pressure of the squeegee for printing machine include the roller pressure, the difference between the soft and hard blades, the angle between the squeegee and the printing plate, etc. The greater the inclination, the greater the pressure. If the pressure is too high, the transfer rate of the ink will be reduced, which will cause greater wear on the printing plate and the scraper; if the pressure is too small, it will easily cause dirty plates or scraping lines. 鈼?The distance between the squeegee for printing machine and the printing plate is reduced, which can improve the ink transfer rate, but it is easy to produce a dirty version; on the contrary, it can solve the dirty version and avoid some small line marks, but it will reduce the ink transfer rate. 鈼?/strong> The flatness and warpage of the squeegee for printing machine mainly depends on the installation method. Of course, it may also be related to foreign matter stuck in the slot of the tool holder or on the blade or lining. When the flatness of the squeegee is poor, some water drop marks will appear on the edge of the printing surface, or some intermittent line marks will appear from time to time. Some people think that the above phenomenon occurs when the ink is rough and the ink flow is not good. In fact, this can also happen with uneven knife edges. Note: When the squeegee for printing machine moves and prints line marks, one is that the plate is damaged, and the other is that the squeegee is not sharp. Another reason, however, is that foreign objects get stuck behind the blade. The solution is to move the squeegee up and down to remove the buildup. If you can't get rid of it, you can only stop and wipe the scraper.Wholesale Ink Scraper website:http://www.nj-heshen.com/ink-scraper/
