Abstract: A method for printing a substrate with radiation curable ink supported on a substrate which includes the steps of providing an inkjet print head at an operating temperature, jetting droplets of the curable ink from the inkjet print head onto the substrate, controlling the interaction between the ink and the substrate, and then curing the ink received on the substrate by directing radiation toward the substrate, wherein the controlling of the interaction is provided for by applying an ink comprising a carrier composition and an agent that is able to reversibly gel the carrier composition, which agent is soluble in the carrier composition at the operating temperature of the inkjet print head and gels the ink when it is received on the substrate. Also provided is an ink for enabling the use of the method and a printer adapted for applying the method.

Abstract: A hot melt ink which includes a colorant, a binder, and a carrier obtained by the reaction of a C6-C24 alkylketene dimer with a reactant selected from an alcohol, an amine, a mercaptan, a carboxylic acid, a carboxaminde and ammonia.
