Abstract: Disclosed is a scanning system havinga light source,a collimator lens,a scanning unit anda scanning objective. The present invention is distinguished by that for the correction of the chromatic aberration over a large wavelength range, only the transverse chromatic aberration of the scanning objective is corrected, and that the intersection lengths of the light rays having wavelengths in the wavelength range over which the scanning system is to be corrected chromatically is dimensioned after the collimator lens in such a manner that the longitudinal chromatic aberration of the scanning system is compensated as well.

Abstract: A method for the production of environmentally compatible decorative labels, which are produced without using a PVC film, is described. The method involves the application of an embossing film, which is capable of transferring heat, on a substrate comprising a separation paper, an adhesive layer, and a plastic film made of homopolymers or copolymers of ethylene with a crystallite melting point (DIN 53765) of 110.degree. to 120.degree. C., a heat of fusion (DIN 53765) of 125 to 180 J/g, melt index (DIN 53735) of 2.0 to 3.5 g/10 min. The embossing film contains a melt adhesive layer that can be activated at 110.degree. to 230.degree. C. The embossing process takes place at a temperature of 110.degree. to 230.degree. C. under a pressure of 1.0 to 7.0 bar for a period of 3 to 0.3 sec.
