21. A system for high resolution digital embossing by printing a polymer overlayer over a printed file, comprising: a digital printer; a controller communicating with said digital printer; and a workstation communicating with said controller, said workstation comprising: a first storage unit for storing digital images of printed files; an image processing module adapted to analyse files from said first storage unit, said image processing unit comprising means for identifying text characters in said analysed files; a polymer percentage calculation module comprising a lookup table adapted to determine a percentage of polymer pixels reduction for identified text characters; a raster image processor communicating with said first storage unit, said image processing module and said polymer percentage calculation module, said raster image processor adapted to create a raster image for a polymer overlayer to be printed over the printed areas of said printed file, said raster image comprising stochastically removed pixels from the overlay area concurrent with each said identified characters, according to said determined percentage.
23. The system of claim 21 , additionally comprising a second storage unit communicating with said raster image processor, for storing raster overlay images.
