cze Vliv povrchového napětí pryžového potahu na přenos flexotiskové barvy Práce se zabývá sledováním vlivu povrchovéhovlastností nových organokovových fotoiniciátorů, schopných iniciovat kationtovou polymeraci tikových barev. Rychlost polymerace byla sledována metodou FTIR. fotoiniciátor, UV polymerace, kationtová polymerace, FTIR
eng Influence of Rubber Surface Tension on Ink Transfer in Flexography The influence of surface properties of rubber sleeves on the efficiency of flexography printing ink transfer on paper at model conditions was studied. The surface tension of the rubber solid was evaluated by means of the measurements of contact angles of standard liquids, using the Owens-Wendt approach. Ink transfer efficiency of two sorts of flexo inks (solvent- and water-based) was evaluated using special laboratory instrument. The focus of this study was to demonstrate the influence of surface tension of the EPDM rubber solids and ink composition on the ink transfer efficiency. photoinitiators, UV polymerization, cationic polymerization, FTIR
