Digital BW, The Print

Thanks for response- never heard of Sihl- want to get some and try. 
Since I don't have a Z3100, I'll try on the 4800- not sure whether to
use matt or photo black ink cart (matt installed now).  It sounds like
you're saying the Epson can't achieve this look because no gloss
enhancer or use of both blacks.  How is metamerism when doing warm
tones with the Z3100?  I think I'm getting some with the Epson.  Your
website very interesting.  Thanks......
