Abstract
A method and apparatus for providing improved address resolution in a rasterization system. The rasterization system of the present invention comprises a pattern database, a pattern delivery computer, a rasterizer and a radiant energy system in which a plurality of logical passes are made across a substrate to produce photolithographically formed patterns. The plurality of passes use a combination of offset printing techniques and application of energy to photosensitive material at a plurality of intensities to provide improved address resolution.
