Abstract
A printer includes a printer carrier having a surface for receiving ink for transfer printing onto a carrier material, such as paper. Areas of the surface print carrier are ink attracting and others are made ink repelling. The ink repelling areas are formed by providing the surface with a layer of a substance in a solid phase, such as water in the form of ice. The ice layer repels the ink as it is applied so that the ink is only held on the surface of the print carrier at the areas that are ice free. The ice layer is formed by cooling the surface using a cooling mechanism to form a coating of frost due to condensation. A surface tension reducer for water is coated on the surface prior to cooling the surface. A laser or other radiation emitter structures the ice layer to form the print image.
