ABSTRACT:
A method of exposing imaging data onto a sensitized medium including exposing K sets of N of tracks on to the medium according to a corresponding part of imaging data, each successive set being a pixel distance apart in a fast scan direction. The method further includes exposing L sets of N tracks onto the medium with an offset of M pixels in a slow scan direction substantially perpendicular to the fast scan direction, according to a second corresponding part of imaging data. The method includes repeating alternately exposing K sets and L sets of N tracks until the complete medium is exposed along the fast scan direction. During or after the alternately exposing K sets and L sets, there is progression in the slow scan direction such that after exposing the complete length of N tracks of exposed pixels, the next N tracks match along the medium at the start of the next N tracks.
