Thanks Mark and Ernst.
Your feed back has been very helpful.
I downloaded a trial version VueScan and outputted a 'Raw format" scan of the water color paper.
Photoshop clipping level display show the same clipping of paper texture I have been seeing with EpsonScan in 'no color adjustment' mode.
and silverfast histogram. So it looking more like a hardware calibration issue.
second 10000xl
I remembered that there is another 10000xl scanner on campus, and it's only a year or two old.
I scanned the same sample of water color paper with epson scan with 'no color adjustment' and it too clipped the paper texture in almost exactly the same way and extent as my 10000xl. There is a third 10000xl that I might be able to get access to. But with both 10000xl's I've tried so far doing exactly the same thing to my water color paper texture, my issue is starting to look more like a 'Feature' of the Epson 10000xl rather than a mistake .
Regards
Peter Miles

Like for Vuescan it is a rendered three channel image file (or four channels if a film scanner with infra-red capability).
