QTR-Quadtone RIP

Maybe this is old news and I just missed it.

I'm on Windows 7 and use PS CC for many things, but I kept CS5 for (among other things) making ICCs with QTR's Create ICC-RGB. PS CC originally would not allow the printer driver "No Color Adjustment" output through it without alteration. It would automatically either set the Print screen to "Photoshop Manages Colors" (where there was no appropriate profile option) or take the Epson driver off "No Color Adjustment." So, I used CS5, with my workspace at Adobe RGB. In the PS Print screen I selected Adobe RGB as the profile, thus, in effect, having a "no color management" option -- a pass-through of the driver's output without PS altering it.

Now what I find is that my PS CC *will* allow me to set "No Color Adjustment" in the Epson printer driver and keep CC's Print screen at "Printer Manages Colors." I compared the final 21-step print Lab L values when CC had this setup with the CS5 approach of having Adobe RGB be the profile, and the outputs are identical.

It appears to me that Adobe is now allowing, in effect, a "No Color Management" option by simply allowing us to set the Print screen to "Printer Manages Colors."

(With respect to another CC function I avoided -- select by color range -- it also appears my CC works much better now. A major upgrade must have been downloaded automatically.)

I don't know, Paul, but I'd suspect that the setup you are talking about:

In PS -- Printer Manages Color

In Epson driver -- select a paper and No Color Adjustment

will convert to the Paper's builtin ICC profile.

You';d have to figure out a test to be sure but seems like this is just

the standard -- let-the-driver-apply-the-printer-profile mode

Have you used/compared ACPU ? This is what they claim to be real

"No Color Management".

Being on a Mac things may be different -- I've got another print dialog page

that is called Color Matching. Under it there's ColorSync and Epson Color Controls.

I tried both CS6 and CC and on both this Color Matching selection is what changes

what you can select in the Epson print settings.

With ColorSync -- to shows an ICC profile and only No Color Adj in Epson settings.

For what its worth.

Bottom line is usually: whatever works -- use it.

Check out the graphs I posted at

I have the Adobe utility. I think it's a hassle to use, and the CS5 - Adobe RGB profile pass-through seemed to produce ICCs that made the expected gamma 2.2 Lab L ramps. Now CC seems to be doing it, but I'm between setups at the moment and can't easily do more testing. I'll probably be back in testing mode by the end of the week.

I was under the impression that printing straight thru was always possible in the Windows environment, and not possible with recent PS/OSX setups.

For Macs there's Print Tool; ACPU and OSX's ColorSync application.
