Abstract
A method and apparatus are disclosed for producing an image made up of marks having varying sizes, densities and/or shapes on an imaging media. The image is generated in response to image data defining the image to be produced received by an input scanner or other input device. The image data is processed and then used to address at least one amplitude and/or pulse width modulation table to, in turn, generate amplitude and pulse width signals which controls a writing device. Marks are therefore written onto the media, such marks having varying sizes, densities and/or shapes for forming the completed image.
