In order to print the materials o# set printing plate is supposed to be fabricated as a master. Although aluminum substrate based o# set printing plate PS plate is commonly used the fabrication process has some problems : strong basic waste from the development process is discharged and the aluminum substrate must be discarded after printing. In this work we have fabricated photocatalyst (TiO ) -based o# set printing plates on aluminum and titanium substrates respectively. The printing plates were fabricated by the combination of four steps : + ) TiO and organic layer were deposited on the substrates ) water-based ink patterns as a photomask were deposited by ink-jet printer on the substrates -) UV irradiation to decompose organic layer due to the photocatalytic reaction of TiO.) water washing to remove water-based ink patterns. We in actual have succeeded to print in color and black and white using the fabricated printing plate. Interestingly the fabricated o# set printing plate can be renewed by a removal of organic layer under UV irradiation. The renewed printing plate demonstrated the high quality printing as well as initial one. This methodology to fabricate photocatalyst-based o# set printing plates o# ers a new resource-saving environmentally friendly printing method.
