Title: Method and apparatus for modifying raster data

Abstract: A print drive that is placed in a prepress workflow between a raster image processor and an output device receives first and second raster data corresponding to first and second image data, and processed by the raster image processor. The print drive uses the second raster data to modify the first raster data. In one embodiment, the first raster data is digitally combined with the second raster data using a digital doubleburner. In another embodiment, a digital masker uses the second raster data as a mask to selectively delete a portion of the first raster data. When used in succession, the digital masker and the digital doubleburner permit the editing of raster data which is rendered through the output device as a modified printed image.
