Abstract (en)
A method and apparatus for enhancing color fidelity in a printing process employing an intermediate member (10) wherein a developing unit (9) deposits a colorless and transparent material directly onto the intermediate member before transfer of any color toner images thereto. Alternatively, a developing unit first deposits the colorless and transparent material on a latent image member. The colorless and transparent material is then transferred to the intermediate member before transfer of any color toner images thereto. Color toner images are then transferred, in registration, onto the intermediate member over the colorless and transparent material, at each of a plurality of image producing stations (20,18,16,14). The resulting combined image, together with at least some of the colorless and transparent material, is then transferred (52) to a copy sheet. The colorless and transparent material provides a glossy appearance to the final image on the copy sheet. <IMAGE>
