Abstract
A printing drum for a liquid electrophotographic printing system which comprises a photosensitive surface and a heating device mounted to the printing drum. The heating device heats the photosensitive surface of the printing drum to a predetermined temperature.
Claims6
A liquid electrophotographic printing system, comprising an intermediate member, at least one printing drum, comprising:
- a photosensitive surface, a heating device, and a controller electrically coupled with the heating device;
- wherein the at least one printing drum is selectively engaged with the intermediate member during a press-priming process and wherein the controller is to control the heating device such that the photosensitive surface is heated to a press priming temperature higher than 80° C. to heat the intermediate member during the press-priming process.
A method to heat a photosensitive surface of a printing drum in a liquid electrophotographic printing system, comprising:
- heating the photosensitive surface with a heating device mounted to the printing drum to a temperature higher than 80° C. during at least one of a print quality enhancing process to enhance the print quality of the photosensitive surface and a press priming process;
- and
- selectively engaging the printing drum with an intermediate member of the liquid electrophotographic printing system during a printing process and heating, by means of the heating device of the printing drum, the intermediate member during the printing process.
