One of the major obstacles in raster graphics has been the artifacts due to aliasing in discrete sampling of continuous curves. These distortions may appear as `jaggie stair-case,' `edge ticks,' `roundup tips,' `squared corners,' and `filled ink-traps.' These distortions that occur in the higher spectrum of human vision create subtle unpleasant effects. Resolution enhancement technology employs a set of piecewise continuous rules to improve output quality by extrapolative prediction beyond traditional anti-aliasing algorithms. The first commercial version of this post processor has more than 200 rules capable of enhancing video streams on the fly. The enhanced print quality has an effect of more than doubling the perceived resolution in field print quality tests.
