    Abstract: There is described a process of measuring print-to-print register of a multicolour print (A-D) provided in an effective printed area (EPA) of the surface of printed material, which multicolour print (A-D) is formed on the printed material by means of one or more printing presses and includes at least a first pattern (A) and a second pattern (B) distinguishable from the first pattern (A). Measurement of an actual print-to-print register between the first and second patterns (A, B), as reflected on the printed material, is derived from processing and finding a correspondence between (i) at least one sample image (SI A , SI B ) of the printed material covering at least a portion of the first and second patterns (A, B), and (ii) at least one corresponding reference image (RI A , RI B ) generated using prepress design data of the first and second patterns (A, B). Also described is a measuring device for carrying out this process and a process of measuring and correcting print-to-print register of a multicolour print.

    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).

    Abstract: There is described a sheet-fed stamping press (10*) comprising a foil application unit (2*) designed to allow transfer or lamination of foil material onto successive sheets (S), which foil material is fed to the foil application unit (2*) in the form of a foil carrier (FC) supplied by means of a foil feeding system (3). The foil application unit (2*) comprises a stamping cylinder (21) with circumferential stamping sectionS (210) provided on a circumference of the stamping cylinder (21) and comprising successive stamping segments (211*; 211**) distributed one after the other about the circumference of the stamping cylinder (21), the stamping cylinder (21) also acting as sheet-transporting cylinder and comprising multiple sheet holding units (21 a) distributed about the circumference of the stamping cylinder (21) and designed to hold successive sheets (S) against the circumference of the stamping cylinder (21). The foil application unit (2*) further comprises a plurality of counter-pressure units (25) distributed about a portion of the circumference of the stamping cylinder (21) and designed to press the successive sheets (S) and the foil carrier (FC) against an outer surface of the stamping segments (211*; 211**), the foil carrier (FC) being supplied by the foil feeding system (3) between the sheets (S) and the stamping segments (211*; 211**). Each counter-pressure unit (25) is designed as a cylinder unit (250, 255) provided with at least one circumferential pressing element (255) positioned to cooperate with the circumferential stamping sections (210) of the stamping cylinder (21), and the counter-pressure units (25) are driven into rotation by means of at least one dedicated drive (26).

    Abstract: There is described a web-fed or sheet-fed printing machine for security papers, in particular banknotes, comprising a machine frame (100) in which is located a main printing group (10, 13, 15, 20, 23, 25), the printing machine further comprising an additional printing group (1, 2, 8; 1, 2', 8; 1 ,2", 8), independent of the main printing group, placed upstream of the main printing group with respect to a direction of displacement of the web or sheets for performing additional printing of the security papers prior to printing by said main printing group. The additional printing group comprises an inking module (1) containing at least one inking device (3), and a printing module (2; 2'; 2") comprising a cylinder arrangement including a plurality of cylinders (4, 5; 4', 5', 6', 7'; 4", 5", 6", 7"), the printing module being interposed between the inking module and the machine frame of the printing machine. The additional printing group is constructed in such a manner that the printing module can be decoupled from the inking module and the machine frame for replacement by another printing module without this requiring removal of said inking module (1) from the printing machine.
