In practical operation of webjed rotogravure printing difftculties oJten arise fr01lJ dallJaged or destrqyed rubber-clad pressure €ylmders. Since these damages, 111 mal!] cases, originate from increase of temperature in the elastic cover oJ the ryli1lders, and tbe stress on tbc rylinders, lvitb the actual trend to enlarge the press speed, is continuousty growing, an inrestigation oJ the temperature effect on the elastic prewtre c)'litlder coat is oJ fundamental itlJportance. In the Institute for Printing MachillCry and Printittg Methods at the TH oJ Darmstadt series oJ experiments have been made to get more information on these proble1J,.r
