Abstract:
1. A printing method, which comprises the following steps: providing a printing press having a plurality of printing units and a downstream varnishing unit; initially printing a surface of printing material with an oil-based printing ink in at least one of the printing units in a single run through the printing press; subsequently either coating the printing material with an oil-based matte varnish containing matting means or printing the printing material with a matte ink containing matting means, in a downstream printing unit, on part of the surface having been printed with printing ink, and with at least one material having a low surface energy being admixed to the matte varnish or the matte ink; and then coating the printing material with a transparent glossy varnish on the entire printed surface in the varnishing unit; and preventing the glossy varnish from thoroughly wetting the matte varnish or matte ink due to the admixed material with low surface energy to permit the matte varnish or matte ink to maintain its appearance.
