ABSTRACT:
By using a high or low viscosity transparent toner, with respect to the other color toners, and different amounts of transparent toner lay-down, the gloss of an image printed by an electrophotographic device may be adjusted. By also applying the transparent toner as a negative mask, the differential gloss of the image may be reduced while still adjusting the gloss of certain portions of the image. Further, because different gloss levels may appear different at different viewing angles, transparent toner may be laid down to encode a transparent image within the image being printed. Such a transparent image may be useful as, for example, an authentication means for a document. Additionally, by varying the gloss levels on particular aspects of a printed image, multiple images of different gloss levels, which are prominent at different viewing angles can be made, thereby, a three-dimensional image effect can be achieved on the printed page.
