Patent number: 6125756Abstract: A printing plate which can be repeatedly directly provided with an image and erased and is suitable for a wet offset printing method. The printing plate has a smooth and pore-free surface which is hydrophilic or can be hydrophilized after being provided with an image. The printing plate contains no strong microdipoles and consists of a ceramic, a glass or a metal, in particular of a metal alloy. An erasing and hydrophilizing apparatus preferably integrated in the printing press, repeatedly erases and prepares, i.e. rehydrophilizes, the printing plate for a further image-providing and printing process.Type: GrantFiled: October 5, 1998Date of Patent: October 3, 2000Assignee: MAN Roland Druckmaschinen AGInventors: Barbara Nussel, Hartmut Fuhrmann, Horst Dauer, Josef Gottling
