• Sheet materials employed for security elements with features positioned with gage pin precision on the front and reverse side are known. Such features may be for example printed letters, figures, symbols and the like.
• Such security features are conventionally produced by gage pin-accurate and register-accurate lamination of at least two imprinted carrier substrates.

• the carrier substrate imprinted on one side is subsequently guided over a turning station and imprinted on the second, opposite side with the corresponding features with gage pin and register precision.
• front and reverse side can be imprinted according to the method described in AT 412273, wherein imprinting of front to reverse side in precise registration of the substrate proceeds analogously to the method disclosed in AT 412273.
• the register is measured longitudinally via a preceding measuring device and adjusted to the required register length between two or more actuated tensioning assemblies.
• Determining the correct register length takes place through inline measuring of the register marks and the correct register length is subsequently adjusted through shrinking by means of a dryer or stretching between two or more tensioning assemblies.
• a regulation circuit in particular a register regulator, the material web is inserted under register control via a register roller preceding the first printing unit, with the side register being driven forward via a web control and/or inserted via a pivoting frame, whereupon the material web is imprinted with gage pin and register precision with respect to the already present coating on the other side of the material web.
