A raster image processing system comprising: a computer readable media storing digital information including: information corresponding to an image; instructions for performing raster image processing, RIP, using an over scan RIP technique on the image to generate a bitmap; and a processor configured to: access the stored digital information to retrieve the information corresponding to the image and the instructions for performing the RIP, RIP the image using the over scan RIP technique at a multiple of the desired output pixel resolution to produce a plurality of sub-pixels per output pixel, each sub-pixel having a value set by the over scan RIP technique, the system is characterized in that the processor is further configured to: determine each image output pixel value based on the values set for the plurality of sub-pixels of each image pixel, by first comparing the values of the plurality of sub-pixels to each other and, if that first comparison indicates further processing is necessary, secondly comparing the values of the plurality of sub-pixels to a set background value, and setting the output pixel value based upon that second comparison; and generate the bitmap comprising the output image pixel values. a computer readable media storing digital information including: information corresponding to an image; instructions for performing raster image processing, RIP, using an over scan RIP technique on the image to generate a bitmap; and information corresponding to an image; instructions for performing raster image processing, RIP, using an over scan RIP technique on the image to generate a bitmap; and a processor configured to: access the stored digital information to retrieve the information corresponding to the image and the instructions for performing the RIP, RIP the image using the over scan RIP technique at a multiple of the desired output pixel resolution to produce a plurality of sub-pixels per output pixel, access the stored digital information to retrieve the information corresponding to the image and the instructions for performing the RIP, RIP the image using the over scan RIP technique at a multiple of the desired output pixel resolution to produce a plurality of sub-pixels per output pixel, each sub-pixel having a value set by the over scan RIP technique, the system is characterized in that the processor is further configured to: determine each image output pixel value based on the values set for the plurality of sub-pixels of each image pixel, by first comparing the values of the plurality of sub-pixels to each other and, if that first comparison indicates further processing is necessary, secondly comparing the values of the plurality of sub-pixels to a set background value, and setting the output pixel value based upon that second comparison; and generate the bitmap comprising the output image pixel values. determine each image output pixel value based on the values set for the plurality of sub-pixels of each image pixel, by first comparing the values of the plurality of sub-pixels to each other and, if that first comparison indicates further processing is necessary, secondly comparing the values of the plurality of sub-pixels to a set background value, and setting the output pixel value based upon that second comparison; and generate the bitmap comprising the output image pixel values.
