Digital BW, The Print

Hello,

I'm using an epson 1400 with Hot press natural paper and eboni 6 inks.

I have problems with soft proofing under photoshop :

I have installed Paul's profiles for that printer/paper, and I now have two choices :
a "NCA" profile, and a "cc22" profile as described in the zip file NCA for No Color Adjustment in driver settings and cc22 for Color Controls with gamma set to 2.2

if I try to soft proof with NCA profile, my photography turns dark grey on screen, and when using the cc22 profile, I manage to get something on screen but it seems there's a problem with the black's dynamic range : black turns dark grey and even with a level curve I can't manage to get real blacks ...

I am confused because I don't know wich profile is correct for soft proofing under ps (I would like to print under qtr and don't get the relation with nca and cc22 which are options more related to the epson driver I think)

For soft proofing I'm using these options : Preserve numbers unchecked / Perceptual / black point compensation checked / Simulate paper color 

Note : my screen is calibrated

any thoughts ?

Thanks 
Benoit
