Abstract: There is described a security element (EL) or document (BN), such as a banknote, comprising (i) a substrate (S) with first and second sides (I, II) and exhibiting at least one window region (W) made of a substantially transparent material, (ii) a micro-optical structure (OP) provided on the first side (I) of the substrate (S) and extending over at least a part of the window region (W), and (iii) a printed feature (P1-P3) printed on the second side (II) of the substrate (S) over at least a part of the window region (W), the printed feature (P1-P3) being provided in register with the micro-optical structure (OP) to produce an optically-variable effect (EF) upon looking at the printed feature (P1-P3) from the first side (I) of the substrate (S) through the micro-optical structure (OP) and the window region (W). The security element (EL) or document (BN) further comprises a protective layer (L) acting as printable primer layer and provided on the second side (II) of the substrate (S) over the window region (W) and on top of the printed feature (P1-P3), which protective layer (L) covers the printed feature (P1-P3) when seen from the second side (II) of the substrate (S) and further acts as a contrast-enhancing layer for the optically-variable effect (EF).

Abstract: There is described a hot-stamping press (10; 10″; 10′″) comprising a foil application unit (2; 2*) designed to allow transfer or lamination of foil material (FM) by hot-stamping onto a substrate (S) supplied in the form of successive sheets or successive portions of a continuous web, which foil material (FM) is fed to the foil application unit (2; 2*) in the form of a foil carrier (FC) supplied by means of a foil feeding system (3). The hot-stamping press (10; 10″; 10′″) further comprises at least one UV-curing unit (61; 62; 63) located along a path (A) of the substrate (S) downstream of the foil application unit (2; 2*) to subject the foil material (FM) transferred or laminated onto the substrate (S) to a UV-curing operation. The foil material (FM) is provided with an adhesive intended to ensure adhesion of the foil material (FM) onto the substrate (S), which adhesive comprises a combination of hot-melt compounds reacting to the application of heat produced by the foil application unit (2; 2*) and UV-curing compounds reacting to the application of ultraviolet radiation produced by the UV-curing unit (61; 62; 63).
