ABSTRACT:
A method by which stacks of printed sheets can be formed and, at the same time, the risk of soiling of the stacked sheets can be reduced to the maximum extent. To this end a printing machine is proposed, in particular a sheet-fed printing machine, into which unprinted and intermediate sheets are alternatively feed, wherein the printing is registered such that the printing occurs only on the unprinted sheets and not on the intermediate sheets. In this way, the intermediate sheets prevent damage to the print on the printed sheets.
