Customization of flexographic printing plates related to uvc-induced changes in the crosslinking degree nonprinting areas are formed. This is because of the presence of oxygen that has a negative effect on the polymerization of the photopolymer during the UV exposure process and thus causes the dots to shrink. Prior to the laser engraving step (30), the photopolymer material is totally cured, followed by removal of a release layer disposed on the material. 1 Imaging of Offset Plates The goal is to generate the ink repelling and ink adhesive areas of an offset plate. We make high resolution digital plates for demanding process jobs, as well as analog plates for those who prefer it. The light penetrates through the acetate where there is no image blocking its way to the photopolymer layer on the plate. There is currently a trend for flat top dots technology in the printing plate industry. Specifications Exposing drying treatment @flexoBag is a brand new development of flexographic plate making system for corrugated & paper printing industryThis innovative creation is experienced from both of conventional liquid photopolymer and solvent plate for 30. IDEAL COVER FILM CF Serves as a separating film between the photopolymer machine and the fluid photopolymer. A cross-link is a bond that links one polymer to another after exposure to UV light. • For safe handling of photopolymer plates, it is recommended to use yellow safety lights or place UV shields on regular fluorescent lighting. The plate material is soft enough to cut with a pair of scissors, so we hand cut individual plates from the larger one. Add reviews and photos for Anderson & Vreeland Inc. Delicate tones are held in photographic images made with the intaglio method, and bold shapes can be achieved with slightly thicker relief plates. From there, the material is exposed similar to a sheet plate, with back exposure to establish the floor and face exposure that creates the actual printing image. 14 mm and 1. Whatever the plate format—liquid, analog, or digital—the same basic chemical reaction in the platemaking process exists. It is supplied as a clear blank slate. The final printed result depends on many factors but an easy-to-use, high quality plate is at the center of the entire process. Each model provides quick and easy exposing of plates. In flexographic printing, the pattern is made into plates, typically from a photopolymer. Free 2-day shipping in the U. Drying Dry the plate in a hot-air dryer.
