>>Then, another problem appeared. I tried to build a new profile and 
import that Photoshop curve into the PFP settings prior profile 
generation. Although the new curve seemed to have been merged into the 
profile, it was done partially only, as the black point remained the 
same. In fact, an inspection gave me the conclusion that the profile 
does not operate on any pixel in range of (0,0,0)~(10,10,10). Is there 
any solution to that? Any other profile editor would give what I desire?

Its not the profile editor at fault; any profile editor can only alter 
values that the printer/driver will allow to be altered. If this 
printer/driver configuration does not allow the deepest shadows to be 
lightened by a Photoshop curve in a PFP profile, then they simply can't 
be controlled from an RGB profile. Sorry to sound unsympathetic about 
your stock of paper you wish to salvage by profiling, but I would make 
this observation:

Trying to beat a bad printer/ink/paper combination into submission 
though profiling is not a very good choice; finding a printer/ink/paper 
combination that performs well is a much better way to achieve good 
results. Every so often I run up against someone just determined to 
make some rather poor combination work by profiling it (almost always 
to save money: on a low cost paper, on third party inks, or on an older 
or low end printer). Inevitably they say they can get improvements, but 
they still aren't satisified. They need to have some perspective about 
this process: it isn't magic, it can make bad combinations better, and 
good combinations excellent; but it can't necessarily make bad 
combinations excellent.

I may be misunderstanding something but can't figure out how to do this:

- Windows XP
- PrintFix Pro 2.0
- Photoshop CS2

After creating a profile, soft proofing in Photoshop CS2 shows that I 
need a Levels Adjustment Layer and Color Adjustment Layer to get what I 
want.

In trying to incorporate these layers into the profile, I think I need 
to use the PFP "Import Curves File" function, is this correct?  And 
these files are
supposed to be in .acv format....

Problem is I have no idea how to save these adjustment curves as .acv 
files.  Double-clicking on the layer doesn't bring up a "Save" option.

Can someone point me to a solution - or tell me I'm misunderstanding 
this whole thing....thanks!

Hi,

Double click on the left side of the layer in the layers palate to 
bring up the curve adjustment window.  Click on save and when 
prompted, name it so you can identify it and note where the acv. 
curve is saved so you can access it from PFP 2. (it is automatically 
saved as *.acv by photoshop)

Hi, 
Sorry for the post below.  I misread your question.  As far as I know 
you need to import a curve from PS (acv).  Not sure if PFP will 
import Levels or Color Adjustment layers.  I suspect it will not.  
You can translate the levels adjustment to curves with a little 
practice and obtain better results many times.  Again sorry I didn't 
read your post correctly the first time.

Thanks Paul, you sorted me out - saving curves works as advertised.  
Somehow late last night I thought it pertained to adjustment layers.
