Abstract

A method is disclosed. The method may comprise applying a coating of electrically charged fluid print agent to a developer surface, the fluid print agent comprising particles of thermoplastic resin in a carrier fluid. The method may further comprise controlling migration of fluid print agent from the developer surface to form an image from fluid print agent on a first surface. The method may further comprise irradiating the print agent on the first surface with ultraviolet radiation to heat the print agent to a temperature of at least 70° C. to melt the thermoplastic resin. A print system and a heating unit are also disclosed.
