A method for manufacturing a value document includes: providing a value document substrate; printing the value document substrate with magnetically orientable effect pigments which are dispersed in a UV-curable lacquer; the step of exposing the lacquer containing the magnetically orientable effect pigments to a dynamic magnetic field; the step of irradiating the lacquer containing the effect pigments with UV radiation; and optionally the step of embossing the cured or at least partially cured UV lacquer.

A method for producing a decorative surface on a workpiece (1) is disclosed, the method comprising the following steps: feeding (S10) of the workpiece (1) coated with a liquid layer (2) to a digital printing station; application (S12) of an agent capable of at least partially absorbing electromagnetic radiation, at least on a partial area of the surface of the liquid layer (2), or which, in contact with the surface, produces a reaction product which is capable of at least partially absorbing electromagnetic radiation.

Furthermore, an apparatus (1) for carrying out this method is disclosed.

In an method for double-sided printing to a recording medium, a first side of the recording medium is printed to with a liquid first color separation, the liquid first color separation is pre-dried such that a predetermined final drying state remains unachieved, where the pre-dried state is a transportable intermediate state that is between a wet print image directly after printing and the predetermined final drying state, a second side of the recording medium is printed to with a liquid second color separation, and the pre-dried first color separation and the second liquid color separation are jointly dried to entirely achieve the predetermined final drying state for both the first and second color separations.

A machine arrangement sequentially processes sheet-like substrates with multiple different processing stations each having a substrate-guiding unit and a substrate-processing unit. At least one of the processing stations has, as a substrate-processing unit, at least one non-impact printing device which prints on the substrate. The processing station with the at least one non-impact printing device has a printing cylinder. Each non-impact printing device is arranged at the circumference of the printing cylinder. The printing cylinder is triple-sized or quadruple-sized. A double-sized or a triple-sized transfer drum, or a corresponding feed cylinder, is arranged directly upstream of this printing cylinder. Alternatively, a double-sized or a triple-sized transfer drum, or a corresponding transfer cylinder, is arranged directly downstream of this printing cylinder.

A press assembly has a plurality of processing stations for the processing of sheets. These processing stations are arranged in succession in a transport direction of the sheets for inline processing of the sheets. At least one of these processing stations is a non-impact printing unit and at least one processing station downstream of the non-impact printing unit is embodied as a dryer. At least one additional processing station is embodied as a coating unit. The coating unit is configured for applying a coating in a form of a varnish to each sheet. A plurality of individually controlled, non-impact printing units are arranged along the transport path of the sheets. Each of the plurality of non-impact printing units is configured as an ink jet printer.
