ADJUSTABLE GLOSS CONTROL METHOD WITH DIFFERENT SUBSTRATES AND 3-D IMAGE EFFECT WITH ADJUSTABLE GLOSS
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.
1 . A method for creating a tilt image on a media substrate comprising:
laying down at least one of a gloss-up transparent toner and/or a gloss-down transparent toner in a pattern of the tilt image over the media substrate; and
fusing the transparent toner onto the media substrate.
2 . The method according to claim 1 , further comprising laying down a varying amount of at least one of the gloss-up transparent toner and/or the gloss-down transparent toner, in a pattern of the tilt image over the media substrate, thereby enhancing the visibility of the tilt image by imparting multiple degrees of gloss thereupon.
3 . The method according to claim 1 , wherein the tilt image appears three-dimensional.
4 . The method according to claim 1 , further comprising laying down a four-color toner image on the media substrate.
5 . The method according to claim 4 , further comprising controlling the differential gloss of the image by laying down a gloss-based negative mask transparent toner layer over at least a portion of the media substrate.
6 . The method according to claim 5 , further comprising controlling the adjusted gloss of the image by applying an adjusted gloss transparent toner layer over at least an adjusted gloss portion of the image.
7 . The method according to claim 6 , wherein the adjust gloss portion of the image is a pictorial portion of the image.
