I have read That black and white prints made with IP5 on the x600 printers 
don't use any yellow ink at all. So I 'm sure this lack of yellow ink in 
black and white printing explains the differance in Whilhelm years, Not sure 
how the epson driver handels the black and white chores. Removing the Yellow 
inks seems to be the answer for metamerism issues.
