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.
Claims15
Method for printing and/or coating of a substrate, especially paper or cardboard, using at least one curable coating, comprising:
- at least one toner layer or an image having at least one 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.
Machine (1), especially digital printer, for application and fixation of a curable toner to a substrate (5), especially paper or cardboard, comprising:
- at least one heating device (13A, 13B, 13C) for melting of the toner transferred to substrate (5), at least one curing device (20) to cure the toner, and a control device to adjust the desired luster, in which the control device adjusts the process parameters of the heating device (13A, 13B, 13C) and/or the curing device (20) for the melting and curing process.
