We have 1400 7.5 minute USGS Topos stored in an ArcSDE raster catalog that we need to get back out to TIFs for use in a non ESRI application. I've exported a half dozen using the CopyRaster_management tool and then built pyramids so they would look nicer when viewed at scales less than 1 to 24,000. In each case the resulting rasters look different then the Raster Catalog when viewed in ArcMap. In some cases there is a cyan bar that shows up across the top of the tif and in other cases black text nearly disappears. The tifs seem fine but the pyramids have problems. Attached is a screen shot of the cyan stripe.
