Abstract

A fabrication process for superhydrophilic-patterns titanium substrates prepared a combination of an ink-jet and site-selective decomposition a self-assembled monolayer (SAM) by a TiO2 photocatalyst under irradiation is described. We demonstrate the prepared titanium is applicable as an offset plate with high resolution (133 150 lines per inch). Furthermore, superhydrophilic-superhydrophobic on the substrate can be deposited after elimination of the by photocatalytic decomposition TiO2 under UV irradiation. A printed image with the renewed showed no significant difference image quality compared with the initial image.
