A method for the manipulation of the differential gloss in a hardcopy output comprising the steps of: selecting a first halftone screen (510, 650) having a first anisotropic structure orientation and a second halftone screen (520, 660) having a second anisotropic structure orientation different from that of the first halftone, wherein both anisotropic structure orientations are similar in density so that diffuse light and reflected light of incident light at orthogonal angles are equal while there will be a difference between them in reflected light of incident light at an angle, which when viewed from an angle will be perceived as a shift in gloss differential or a glossmark image; applying the first halftone screen (510, 650) to at least a portion of a halftone image; applying the second halftone screen (520, 660) to the remaining portion of the halftone image; outputting the halftone image in which said first and second halftone screens are applied with color toner to a substrate; selecting a third halftone screen having a third anisotropic structure orientation and a fourth halftone screen having a fourth anisotropic structure orientation, wherein both anisotropic structure orientations are similar in density so that diffuse light and reflected light of incident light at orthogonal angles are equal while there will be a difference between them in reflected light of incident light at an angle, which when viewed from an angle will be perceived as a shift in gloss differential or a glossmark image; characterized by: applying the third halftone screen to a first portion of a halftone image to be formed with clear toner; applying the fourth halftone screen to the remaining portion of a halftone image to be formed with clear toner; outputting the halftone image in which said third and fourth halftone screens are applied with clear toner to the substrate comprising the halftone image formed with color toner; wherein the first portion of the halftone image to be formed with clear toner provided with the third halftone screen having the third anisotropic structure orientation is applied substantially coincident with the portion of the halftone image to be formed with color toner provided with the first halftone screen. selecting a first halftone screen (510, 650) having a first anisotropic structure orientation and a second halftone screen (520, 660) having a second anisotropic structure orientation different from that of the first halftone, wherein both anisotropic structure orientations are similar in density so that diffuse light and reflected light of incident light at orthogonal angles are equal while there will be a difference between them in reflected light of incident light at an angle, which when viewed from an angle will be perceived as a shift in gloss differential or a glossmark image;

applying the fourth halftone screen to the remaining portion of a halftone image to be formed with clear toner; outputting the halftone image in which said third and fourth halftone screens are applied with clear toner to the substrate comprising the halftone image formed with color toner; wherein the first portion of the halftone image to be formed with clear toner provided with the third halftone screen having the third anisotropic structure orientation is applied substantially coincident with the portion of the halftone image to be formed with color toner provided with the first halftone screen.
