Abstract: There is described a printing press (100***; 100****) adapted to carry out printing on a sheet-like or web-like substrate (S), in particular for the production of security documents such as banknotes, comprising a printing unit (2*; 2**; 2***; 2****) designed to print a first side (I) and/or a second side (II) of the substrate (S). The printing press (100***; 100****) further comprises an in-line casting device (80; 80*; 80**; 80***) adapted to apply a layer of material acting as an optical medium on a portion of a first side (I, II) of the substrate (S) and to replicate and form a micro-optical structure (L) in the layer of material acting as optical medium. The printing unit (2*; 2**; 2***; 2****) is furthermore adapted to print at least one printed pattern on the first or second side (I, II) of the substrate (S) in register with the micro-optical structure (L), wherein the printing unit (2*; 2**; 2***; 2****) comprises at least a first printing group (93) being adapted to print at least one printed pattern on the second side (II) of the substrate (S) in register with the micro-optical structure (L) and wherein the in-line casting device (80; 80*; 80**; 80***) comprises at least one embossing cylinder (85), which embossing cylinder (85) also is acting as counter-pressure cylinder and cooperates with a printing cylinder (8) of the at least first printing group (93) and/or whereas the in-line casting device (80; 80*; 80**; 80***) and the at least a first printing group (93) being arranged at the Substrate transport path such way, that in-line casting of the micro-optical structure, on one side of the sheets S, and printing of the associated pattern, on the other side of the sheets S, are performed in a same step, without this involving any sheet transfer operation.

Abstract: A security device is disclosed having public recognition features for use with security substrates to make security documents. The security device has a partial opaque layer having light transmissive regions surrounded by one or more opaque regions. The transmissive regions define negative indicia which are visible when viewed in transmission but not in reflection. Security features are provided on opposing sides of the partial opaque layer forming sides of the security device. At least one of the security features has indicia which are visible when viewed in reflection from one of the sides and at least partially overlap with the negative indicia. The security device has a low optical density layer which is semitransparent in the visual spectral region and is provided within the transmissive regions. The low optical density layer has a substantially continuous layer of a semitransparent material or a screen of opaque screen elements.
