Abstract
An image processing method (300) for converting an original image (601) into a final, pixelated image (610) suitable for printing on a printer arranged to print two-tone images and capable of printing partial area exposed pixels, comprises antialiasing (301) the original image (601) into an intermediate pixelated image (605) comprising greyscale pixels having assigned greyscale values. The method comprises the further-step, of translating (302) the intermediate image (605) into the final, pixelated image (610) by translating the assigned greyscale values into partial exposure values indicative of the amount of desired pixel area for a corresponding pixel or pixels in the final image.
