Abstract:
Sub-raster registration errors are compensated for through non-redundant overwriting. Data from adjacent rasters is written to a particular output raster so that the adjacent rasters share an influence at a point actually written to by a rendering device, thereby compensating for a sub-raster component of a registration error associated with writing to the particular point. If two writing passes per raster are used and the writing passes have equal influence (e.g., are written with equal power), then writing data from a first raster during a first pass and writing data from a second raster adjacent to the first raster during a second pass compensates for a sub-raster registration error of half a raster spacing. If two writing passes are associated with different influence (e.g., are written with ⅓ and ⅔ power respectively) and/or if additional writing passes are used, then addition sub-raster positions can be compensated for or emulated.
