           Summary: Output image not uniform color
           Product: Ghostscript
           Version: HEAD
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Color
        AssignedTo: michael.vrhel at artifex.com

When the attached PDF file is converted to a raster format (e.g. tiff24nc) at 300 dpi the output is not 
uniform in color (there are horizontal bands in the image, see attached screenshot for an explanation).  At 
lower resolutions (e.g. 72 dpi) no bands appear and the band change at different resolutions.  Adobe 
Acrobat 9.2 renders the file without these bands at any resolution.

The command line I'm using for testing:

  bin/gs -sDEVICE=tiff24nc -r300 -o test.tif ./43353b.pdf
