Abstract (en)
[origin: EP0400595A2] A forme cylinder in an offset printing machine for a direct image transfer by means of a thermotransfer process has a radiation-permeable cylinder shell and, in its interior, at least one source of radiation directed towards the inner shell surface. The source of radiation can emit visible light, infrared, ultraviolet or even electromagnetic rays. The energy transmitted by this radiation can be used for preheating the cylinder shell, for causing or assisting the melting out of the parts of the substance required for the image transfer from a thermotransfer film, hardening or burning-in the parts of the substance on the outer shell surface or assisting or causing the removal of the parts of the substance by heating or decomposition on completion of the printing operation. <IMAGE>
