On PCs, there are two different workflows for printing -- the Epson driver
(best  with an ICC) and QTR, which is used as a stand-alone printer
utility.  They use different profiles.  I initially mostly posted Photoshop
curves and ICCs, with the curves often being embedded in the ICCs using
QTR's Create ICC-RGB.  I did not initially post many (any?) QTR profiles,
as I then assumed most QTR users made their own profiles.  I recently
posted a number of QTR profiles also (see previous thread).

I think  you'll find profiles for those.

I used  to make some ICCs that use the Epson driver settings "Color
Controls" with gamma set at 2.2.  That is what "cc22" stands for.  In think
this  is  discussed in  http://www.paulroark.com/BW-Info/Eboni-6.pdf .  Be
sure to read that PDF.

The newer Photoshop versions and OSs do not allow ICCs to  be combined
 with "Color  Controls."  So, with the current systems these "cc22"
profiles are not usable.

That is for QTR, not the Epson driver.  It uses only the black ink (BO =
Black Only).  In my Zip files that have the profiles in them you'll find
profiles that use the full inkset.  They will be smoother than one that
uses only the black ink.  The black ink is more neutral, however.  With the
1400/30 you can combine these two types of approaches with QTR using the
sliders.  Read the PDF noted above.  I think it explains this.

Hope this helps.
