Abstract
The invention relates to a method for producing a printing plate for waterless offset printing. A method for producing a printing plate for waterless offset printing is proposed, having the following method steps:-providing a substrate;-applying an ink onto the substrate using an inkjet printing technique; and-fixing the applied ink on the substrate. The method is characterized in that the substrate has a surface tension of >35 mN/m, preferably >38 mN/m, and the ink has a surface tension of <30 mN/m, preferably <25 mN/m, when fixed on the substrate. The ink is applied into substrate regions which should not have printing ink during the offset printing process.
Claims14
A method for producing a printing plate for waterless offset printing, comprising:
- providing a substrate;
- applying an ink onto the substrate by means of an ink jet technique;
- fixing the applied ink on the carrier plate;
- wherein
- the substrate has a surface tension of ≧35 mN/m, preferably ≧38 mN/m and the ink in the fixed state on the substrate has a surface tension of ≦30 mN/m, preferably ≦25 mN/m, and the ink is applied in the regions of the substrate, which in offset printing should not carry any printing ink.
