Abstract
The present invention relates to the expedient supply of differential gloss text into a document image, particularly as when desired in the employ of rendering variable data. A font character is selected and sub-sampled. The sub-sampled result is then scaled up into a full size result. A first halftone cell having a first anisotropic structure orientation is selected and applied to the full size scaled font result while a second halftone cell having a second anisotropic structure orientation is applied to the surrounding background around the full size scaled font result to create a gloss font character. This full gloss font character is then stored as a font representation as callable by the digital front end of a printing apparatus.
