Alessandro:

Thanks.  I'll check your tweaks on my printer in the next couple of 
days and report back.  As Paul Roark said, it might just be printer 
variations.

Do you use a spectrophotometer to evaluate the printed GS-Stepwedge 
or do you use a flat bed scanner and PhotoShop or other image editor 
to check the percent value 0-100, (or pixel value 0-255, or density, 
or ??) of the patches?
