Abstract
Wetting and print transfer from a printing patterned transfer surface is enhanced by applying an ultraviolet radiation responsive material to the patterned transfer surface. Ultraviolet activation of the ultraviolet responsive coating is performed during a transfer of printing material to a substrate. The technique increases precision of the printing process and is useful for transfer of printing material to a substrate in order to establish printed circuit components such as circuit traces and printed circuit elements on the substrate. In a particular configuration the ultraviolet radiation responsive material can be made of azobenzene material or free radical initiators.
