Abstract:
A method for accurate reduced-resolution tone reproduction of a printed image based on an image of image values, said printed image being generated by a printer engine with a printer resolution which deposits a marking medium at pixels on a printing surface, an amount of said marking medium deposited at said pixels being a function of printer values for said pixels, comprising the steps of:(a) defining dimensions of a multi-pixel cell of said pixels;(b) defining a set of font cells, each of said font cells having an arrangement of font pixel values for said pixels in said multi-pixel cell and a corresponding font index value;(c) mapping said image values for said pixels in said multi-pixel cell to a corresponding one of said font cells; and(d) printing said font pixel values for said corresponding one of said font cells in said multi-pixel cell on said printing surface.
