Abstract
A method and system for exposing a light sensitive material using device for forming a row of spots of light onto the light sensitive material located on a focal plane, device for modulating each of the spots according to imaging data so that at any point of time, the row of spots forms a data pattern according to the imaging data, device for generating relative motion between the imaging mechanism and the light sensitive material on the focal plane, the direction of motion substantially parallel to the direction of the row of spots on the light sensitive material; and data synchronizing device for shifting the imaging data into the modulating device at a rate determined by the speed of relative motion to maintain the image of any data pattern substantially stationary on the light sensitive material.
