A problem of mismatch in pixel resolution between a front-end device, at one relatively low pixel resolution, and an output device such as a non-impact printer or a display at a higher pixel resolution is overcome by providing for grey level enhancement of low pixel resolution binary image data to minimize jaggies in a printed or displayed image, and then increasing the pixel resolution of the grey level enhanced image data to match that of the output device.
