Digital BW, The Print

To anyone out there who owns one of the new Canon inkjet photo printers 
who also has also made prints with the Epson 1280 or 1160 with OEM dye 
inks:

Have you compared the metamerism of the Canon OEM inks (do they exhibit 
any?) with the level of metamerism when printing with the Epson 1160 or 
1280 with OEM dye inks ?

Thoughts ?
