Process and apparatus for contact printing with supply of release agent through a porous printing surface

A method for printing a liquid onto a material (20) in sheet form, characterized by the steps of: providing a surface (30) of porous printing has holes (32); extruding a first liquid (100) from the holes (32) of the printing surface on the surface (30) of printing; applying a second liquid (200) over and in contact with the first liquid (100) from the surface (30) of printing and contacting the material (20) in sheet form with the surface (30) for printing the second liquid (200) on the material (20) in sheet form. wherein the surface (30) has a printing pattern zone (60) and a non-pattern zone (62).
