Abstract
An image file is prepared for printing. The image file is received. The image file includes a cell having pixels. A pixel of the pixels of the cell corresponds with a command to apply a print substance to a medium. For the pixel, the command to apply the print substance is selectively replaced with a command to not apply the print substance.
