Digital BW, The Print

Keith-

You might want to try the profiles available on the lyson site. I 
haven't noticed a large difference in using them and not using them, 
but they are free and might solve your problem.

I have been using Lyson small gamut (tried one set of quad carts and 
switched to small gamut for the flexibility) and I always convert to 
grayscale and back to RGB. I think there is a bit of posterization 
printing in GS. I'm using a PC with the gamma settings at default, so 
that may be a little different than MAC.

I've found that the Lyson inks print great on almost every glossy 
paper. I especially like the Pictorico High Gloss White Film and 
Epson Premium Gloss Photo.
