Abstract

See full text

The invention relates to a device for producing security elements (03) on a substrate (02), said device having a first printing couple (21; 22), by means of which substrate (02) being conveyed along a transport path is and/or can be printed with a plurality of first print image elements (12) spaced apart from one another using a first coating medium (11) that contains magnetic particles; a first magnetic cylinder (41), arranged downstream of the first printing couple (21; 22) in the transport path and comprising magnetic elements (43) on its outer circumference; a second magnetic cylinder (42), arranged downstream of the first magnetic cylinder (41) in the transport path and likewise comprising magnetic elements (43) on its outer circumference; and a drying and/or curing device (52), associated with or positioned downstream of the second magnetic cylinder (42) in the transport path, by means of which at least the coating medium (13) of a plurality of second print image elements (14), printed onto the substrate (02) and spaced apart from one another, is and/or can be dried and/or cured at least superficially and/or at least each partially, wherein in the transport path between the first and the second magnetic cylinder (41; 42) a second printing couple (31; 32) is provided, by means of which the substrate (02) is and/or can be printed with the spaced-apart second print image elements (14; 12) using the second coating medium (13) that contains magnetic particles, and wherein a drying and/or curing device (51) positioned upstream of the second printing couple (31; 32) is associated with or positioned downstream of the first magnetic cylinder (41) in the transport path, by means of which device the coating medium (11) containing magnetic particles of the first print image elements (12) printed by the first printing couple (21; 22) is and/or can be dried and/or cured at least superficially and/or at least each partially.
