Production of picture by selective application of heat and pressure to substrate

摘要

The printer uses an endless inking band or substrate layer (20) which transfers colored inks onto the picture substrate (19). The inking band is covered with microcapsules. The picture developing device has an endless band (70) running over two rollers (73) and contacting the top surface of the picture substrate. There are several heating elements (34-36) moving at 90 degrees to the direction of motion (A) of the substrate, and pressing against a transverse beam (45). The inking band is pressed against the first endless band. To transfer the inks. Different combinations of pressure and temperature burst different microcapsules to release different coloured inks.
