Abstract

The invention relates to a sheet-fed rotary printing machine with printing units for multi-color printing and with at least one coating unit. The object of the invention is, inter alia, to provide a sheet-fed rotary printing machine of the type described in the introduction, in which at least one coating unit can be used more universally and set-up times are reduced. This is achieved in that the coating unit 2, 3 is formed from an impression cylinder 10, a form cylinder 12 and a metering system 14 with a screened applicator roller 13. The applicator roller 13 has a circular segment congruent to the cylinder pit of the form cylinder 12, is at least the same size as the form cylinder 12 and can be imaged as a rough intaglio printing form.
