Digital BW, The Print

Excellent Paul! Thanks!  I just got a new iMac and one reason was I was
having driver issues with the Epson 1400 on my PC.  It worked great at first
but then all of a sudden started taking 5 minutes per command within the
driver and to print.  Nothing I can figure out!  Anyway, time for a computer
upgrade anyway and this iMac with 8GB RAM and a real fast graphics card has
been at lightning speed with my meduim format scans and my Nikon 9000
scanner.  Now, to hopefully use your new 1400-Eboni-6 profiles!

Thanks again!  I'll share my successes and results.
