Having a problem with ArcMap 10.0 SP1 Data Frame Grid of graticule inverting color on export or when printing.
Occuring on multiple classroom PCs all working with the same datasets. Exporting to raster formats (PNG, JPEG) with resolution set under 149 dpi layout renders correctly. But with any higher resolution, or for export to a mixed vector raster mode (PDF, AI) the Data Frame Grid inverts color (gradicule goes white--remainder of grid layer is solid black). As this is the top layer of the map layout it renders the map useless. Also, it does not occur when raster layers in the MXD are all turned off, just when one raster is active.
I assume the Data Frame Grid from the layout is converted to a raster layer as part of the print or export by some library. Does anyone have a good grasp of where this occurs and how the conversion can be adjusted to prevent inversion for reliable printing and export results?
