Abstract:
A sheet-fed printing system, comprising:a source of printing medium; a support frame at least partially enclosing the sheet-fed printing system; a transfer element rotatably supported by the support frame; a source for directing ultraviolet radiant energy at a substrate being printed with the pointing medium, the source substantially disposed within the support frame and positioned proximate the transfer element, some of the radiant energy absorbed by the transfer element thereby raising a temperature of the transfer element; and a cooling unit configured for generating and directing a cooled airflow onto the transfer element, the cooled airflow maintaining the transfer element within an effective temperature range such that the substrate being printed distorts less than an allowable substrate distortion limit, the cooled airflow substantially generated from air at least partially present within the support frame and previously cooled by the cooling unit.
