摘要：
A method of exposing imaging data (542) onto a sensitized medium (550) including exposing K sets (380, 480) of N of tracks (1, 2, 3, 4) onto the medium according to a corresponding part of imaging data, each successive set being a pixel distance apart in a fast scan direction (301, 401). The method further includes exposing L sets (390, 490) of N tracks onto the medium with an offset of M pixels in a slow scan direction (302, 402) 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.
