Abstract
A device for printing additive color images comprising a modified desktop wire printer, a set of print wires with surface relief diffraction gratings incorporated at the tips, a steel print platen and a print substrate made of thermal plastic material, is disclosed. The striking strokes of the print wires impress a large plurality of tiny dot of diffraction gratings onto the substrate via the mechanism of micro embossing to form the image. Color differentiation is accomplished by varying the pitches of the diffraction gratings in the dots. An alternating technique of transfer printing to produce similar result is also disclosed.
