Abstract

Wet offset printing plate comprises a top layer of a material that can be photocatalytically converted to a hydrophilic state by irradiation with light and converted to a hydrophobic state by heating, where the layer includes absorption centers for radiation, especially near infrared (NIR) laser radiation, such that the layer can be heated imagewise. Independent claims are also included for the following: (1) a process for writing such a plate, comprising imagewise heating of the plate; (2) a process for erasing such a plate, comprising irradiating the plate with UV light while supplying water; and (3) apparatus for repeatedly writing such a plate, comprising a writing device for imagewise heating, an erasing device comprising one or more daylight and/or UV light sources, and a humidifying chamber for generating and maintaining a predetermined air humidity on the plate.
