Hello. I'm epson 9900 user.
I would like to use ABW profile for linearity.
Does the possible to use ICC profiles with epson ABW in ps CS6?
Also, Does the possible to create linearising abw profile using the QTR with spyder SR?
If I don't use ABW, Does the possible to b&w pringting without colorshift when only use RGB icc profile?

No...ABW is a non-color managed black box.

Not in CS 6.  QTR Print Tool will on a Mac.  Works well.

Why couldn't you, say, send your Grayscale target through ABW, measure it, make your profile, then convert your print file to that Grayscale profile, then Assign sRGB and send it to the printer. That would add a couple of steps, and I haven't tried it yet, but it seems like it should fool the driver into using a pre-converted file that has the profile already applied.

Old, doesn't fly any longer in modern versions of Photoshop on Mac.

As Jeff said, ABW is a black box. The idea is to let it do the heavy lifting by converting a color image. The degree of control over this is, well not for those that want to fully control the process outside ABW. If you are doing this kind of work, doing your own toning etc, then you'll need to use an ICC profile without ABW.

I was not aware of the problem on Mac.

I agree with your point on doing without ABW.  It is also the way I do it and am very satisfied with the results.  ABW is kind of working blind.

Hey Jeff,

Well, I think it's more accurately a non-color managed black and white box. :p

Cheers,

Still works OK on CS6/Win7, and still gives just a bit better linearity and Dmax.

That is correct for now.  Epson have not updated the Win print driver and one can still use ABW profiles under this OS but not Mac.  My test results confirm what was noted just above.  Better linearity and Dmax.  You can get the same linearity using the normal Epson driver if you have a set number of B/W patches when you do your profiling.  I always include 21 B/W patches when I do my profiles with Argyll.  The slight downside of using the normal driver is a little more colored ink is used and your Dmax is about 5-8% lower depending on the paper than with the ABW driver.
