Abstract
A laser induced thermal imaging (LITI) donor film having a substrate, a light-to-heat conversion layer overlaying the substrate, and a transfer layer overlaying the light-to-heat conversion layer. A surface of the transfer layer includes microstructured or nanostructured features, in a continuous or discontinuous pattern, embossed or otherwise imparted in the transfer layer. The features provide break points to assist in release and transfer of portions of the transfer layer to a permanent receptor in a pattern defined by the features.
