Hiya David,
I remember the trouble I had trying to get true colours with my Epson (although it wasn't an r220). In the end I gave in and just got the photo good on screen and ran numerous small prints off, altering the colour in Photoshop until it looked good, then just changed each print I did to the final settings I got to

.
However I've just found this, which is a step by step tute on setting up an r220 with CS3, hope it helps......
John
