ABSTRACT:
The printer's page description contains a contone layer and a black layer. The black layer is conceptually above the black layer and is composited over the contone layer by the printer. The print driver therefore maintains a page buffer which correspondingly contains a medium-resolution contone layer and a high resolution black layer. It is therefore necessary to determine where an object being placed on the contone layer obscures something on the black layer. When an obscuration occurs the obscured black pixels are composited with the contone layer and removed from the black layer.
