Abstract

A machine for application and fixation of curable toner through a substrate and a method for printing and/or coating a substrate, especially paper or cardboard. The method includes the use of at least one curable toner in which at least one toner layer or at least one image having a toner layer is transferred to the substrate and fixed on it, the toner being a UV curable toner having at least one polymer that is exposed to UV (ultraviolet) radiation for crosslinking of its polymer chain. The degree of melting of the toner layer being fixed being controlled as a function of the desired luster.
