Abstract

Embodiments of the present disclosure provide a method for estimating usage of a print substance. The method comprises receiving a plurality of pixels of a page to be printed, and generating, for one of the plurality of pixels, a look-up address based on (i) pixel bits of the one of the plurality of pixels, and (ii) pixel bits of one or more other pixels proximal to the one of the plurality of pixels. The method further comprises estimating an amount of print substance deposited on the page at a location associated with the one of the plurality of pixels based on reference to a print substance amount in a table of print substance amounts, wherein the reference to the print substance amount in the table is made using the look-up address.
