SAVING MARKING MATERIAL USING THRESHOLD ARRAYS AND TONER REDUCTION MASK

Methods and devices create a first halftone image and a different second halftone image from a continuous tone image. A third halftone image is produced by identifying pixels that are common to both the first and second halftone images. A toner reduction mask is applied to the third halftone image to produce a fourth halftone image (the fourth halftone image has only holes and remaining ones of the common pixels). The holes are added to the first halftone image to create a reduced-toner halftone image. Further, edges of features within the continuous tone image are detected (to identify edge pixels of the edge features) and such edge pixels are added to the reduced-toner halftone image to produce a print-ready halftone image. Finally, such methods print the print-ready halftone image on print media.
