Abstract:
A clean running flexographic relief image printing element and a method of making the same is described. The relief image printing element comprises (a) a backing layer; (b) a floor layer disposed on the backing layer and comprising a photopolymer containing a silicone monomer or silicone oil, wherein the cured floor layer has a surface energy of between about 18 to about 25 dynes/cm; (c) a cap layer disposed on the floor layer and comprising a photocurable composition that is capable of being imagewise exposed to actinic radiation to create a relief image therein, wherein the cap layer has a surface energy of between about 30 and about 40 dynes/cm; and (d) a removable cover sheet. The differential of surface energies between the floor layer and the cap layer increases how clean the plate will print over time.
Abstract:
Provided are a gravure printing plate and a method of manufacturing a gravure printing plate, which are capable of increasing a density range as compared to the conventional case to enable suppression of moire as well as to achieve rich gradation and enable fine tone settings. The gravure printing plate includes FM screen cells and AM screen cells which are concurrently formed in a plate surface thereof, and the FM screen cells and the AM screen cells are different in depth. It is preferred that, of the cells which are different in depth, shallower cells correspond to subcells and deeper cells correspond to main cells.
Abstract:
Provided is a cliche and a method of manufacturing the cliche which can increase or maximize productivity and production yield. The manufacturing method of the cliche includes providing a substrate, forming organic patterns protruding on the substrate, and forming an ink absorption layer on the organic patterns or on the substrate exposed from the organic patterns.
