That's a good idea and one I should probably have thought of. I think my brain is turning to mush comparing all these scanners etc. ;-)
I will check to see if there is a range of values between 210 and 255. I will try and use the built-in ColorSync calibration on the Mac to get a better image but the dealer is a bit touchy about doing things to his monitor (although he should thank me if the calibration is wrong). Thanks for the advice.
