  • Printing method for producing matte and glossy printed surfaces
    Patent number: 7856926
    Abstract: A printing method, using a printing press having a plurality of printing units and a downstream varnishing unit, includes 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. The printing material is subsequently either coated with an oil-based matte varnish containing matting means or printed 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. The printing material is then coated with a transparent glossy varnish on the entire printed surface in the varnishing unit. A printed product is also provided.
