Abstract
A process for printing and/or coating of a substrate, especially of paper or cardboard, is proposed. The process calls for at least one toner layer (1) to be transferred to the substrate and fixed on it, the surface (3) of a gloss variation device (5) acting at least in sections on at least one fixed toner layer (1), or one toner layer (1) in the course of being fixed, in order to influence the gloss of the fixed toner layer (1). In the process, depending on the gloss to be achieved, the force with which the surface (3) of the gloss variation device (5) acts on at least one toner layer (1) and/or at least one property of the surface (3) of the gloss variation device (5) is changed.

Process for printing and/or coating of a substrate, especially of paper or cardboard, in which at least one toner layer (1) is transferred to the substrate and fixed on it, the surface (3) of a gloss variation device (5) acting at least in sections on at least one fixed toner layer (1), or one toner layer (1) in the course of being fixed, in order to influence the gloss of the fixed toner layer (1), characterized in that depending on the gloss to be achieved, the force with which the surface (3) of the gloss variation device (5) acts on at least one toner layer (1) and/or at least one property of the surface (3) of the gloss variation device (5) is changed wherein changing at least one property of the surface (3) of the gloss variation device (5) comprises the elastic change of the dimensions of the surface (3) of the gloss variation device (5).
Device for printing and/or coating of a substrate, especially of paper or cardboard, with a fixing device for fixing of at least one toner layer (1) on the substrate, and with a gloss variation device (5) which acts on at least one fixed toner layer (1), or one toner layer (1) in the course of being fixed, in order to influence the gloss of the fixed toner layer (1), wherein the gloss variation device (5) has a surface (3) with elevations (11) which surface acts with variable force on at least one toner layer (1) and/or of which at least one property can be changed to influence the gloss of at least one fixed toner layer (1);
- wherein the distances (9,9′) of the elevations (11) of the surface (3) of the gloss variation device (5) can be changed.
