Abstract
A donor element for proofing having at least a transfer material disposed on a substrate for the preparation of a digital halftone proof having consistent dot density characteristics over time. The donor element includes a transfer material having a donor binder, a cationic infrared absorbing dye, a thermally activated crosslinking agent and a dispersible material The donor element can also include a distinct, intermediate transfer layer disposed between the substrate and the transfer material. The donor element can be used in conjunction with a receptor element to provide a thermal imaging system.
