Abstract
To prevent banding in a flat field exposed--by means of a linear array of photosources--upon a moving photosensitive web, the invention not only provides that the photosources be pulsed in correspondence with the movement of the photosensitive web, but that the lengths of the printing spots which are employed be equal (or approximately so) to the raster line spacing, whereby smear of any one exposure spot will blend into the smear from the next exposure spot to provide a perfectly flat field exposure.
