Digital BW, The Print

Hello, this is my second post!

I was glad to see in the Files section that the Epson inks used 
through ImagePrint was about comparable to Piezography in quality. 
But as I mentioned in my RIP post ImagePrint is very expensive for a 
7600. I would really appreciate if somebody could put me on the 
correct road to ensure that I produced the best possible B&W print on 
a 7600 without having to pay big money. 

Many thanks (again) 

David
