Digital BW, The Print

Greetings,

Does anybody know of a high quality postcard paper (printed on back 
with postcard mailing lines etc.) that will work well with PK ink in 
Epson 3800. Ideally I am looking for a silver rag, Harmon gloss etc. 
type of high grade coating on a postcard stock. Can anybody help?

Thanks,

Scott Jones
