Digital BW, The Print

Hello,

for three month, I've tried many way in order to print photo with my
Epson 790 (6ink set).
I use Lyson QuadBlack set of inks and Lyson paper (matt paper).
My photo are going from ilford HP5 scanned with a Minolta dual scan II.

I've tried many workflow found in this forum.
I've used the ICC profile given by Lyson.
I've tried to calibrate my own a transfer curve in Photoshop...

And I've no good result.

The best result is to use glossy paper (I've tried this morning) with
printing in greyscale (No color !!!).

So, before going mad, could you explain why I can get good printing by
using grey printing and no color printing like it's urged in the Lyson
documentation ???

I doesn't use any ICC profile, I just set to gamma 1.8 (like my
macintosh display) and get result that is correct according to my
trustee Photoshop !

It's very bad because now, I just want to throw all of this and to buy
 a good enlarger and go only chemical. First, I've a Nikon coolpix 995
now I've a Nikon FM3a (mechanical chemical). Now I think that photos
is just matter of chemical process !!!

If I can't trust the process I will change it !!!


HELP ME !!!
