Digital BW, The Print

Thank you again for all your helps!

After reading the whole service manual I controlled all the 
mechanical parts and they looked absolutely fine. By this chance I 
learned how to fill new inks backwards from the dampers. So I made a 
try and sucked out the ebony black and filled in the original Epson 
black ink. It needed a few cleaning cycles but then all problems went 
away.
It seems that the ebony black didn´t worked in my printer for 
whatever reason. I am not sure if I want a second try with ebony at 
the moment but with the original epson black I dont get an acceptable 
dmax. Therefore I´m thinking to have a try with the Epson mattblack 
from the Epson 7600. Could this be a good idea?

I own also the Epson 2100 and made very good black and white prints ( 
with ugly green and magenta metamerism)in respect of dmax, tonal 
range and sharpness that were also matching exactly the image from 
the monitor. The 2 prints I got from the Epson 7500 with the UT and 
Paul´s curve were far away from the results I expected. I´m sure with 
a lot of experimenting and adjusting you can optimize the prints for 
your own taste but I realy would like to get what I see on the 
monitor. 

After all conclusions I will try now to use the UT with the Epson 
mattblack instead of ebony together with a quadtone rip and self 
generated profiles.

Do you think this is a good idea? Any comments are appreciated...

Regards,

Ingo
