I can't believe this actually is a new topic, but my search turned up nothing so I press on.
I am relatively new to QTR and am finding much of its interface quite baffling and mysterious.
I am using it on a PC. Nearly all of the tutorials I've found are for Macs.
Following instructions found in many places and using WordPad, I am editing and saving an existing qidf file under a new file name.
The first time I did this, the new file appeared in the Curve Setup pulldown.
I made addition tweaks and saved it again under a new name.
This second file does not appear in the pulldown.
What have I don wrong? How do I fix it?
Any help will be much appreciated.
Thanks,
JeffP.S.
The tutorial by Michael Reichmann includes this cryptic (to me) statement that might apply, but I can't figure out why or how to do whatever it is he's suggesting. Mostly because I don't know what a .acv curve is (I'm editing the qidf file, so perhaps it doesn't apply).
"18. From the Gray Curve tab in the QTR Curve Creator browse to the .acv curve and select. The following is why it's important for the curve to have been generated from a grayscale image: if it's not grayscale, you'll get a cryptic error message when you go to save the QTR Curve and the Curve Creation will fail."

Re: [QuadtoneRIP] QTR can find the qidf file I just created.

It's not entirely clear to me what you're trying to do. However, I work with QTR in Windows 7 and might make a few observations.
While the QTR *.quad files (what the rip actually uses) and *.qidf files (what you edit in QTR's Curve Creator) are originally stored under the C:\Program file (x86)\QuadToneRIP\ folder when the program is first installed, after you edit a file, it is put in a hidden folder that is hard to get to. The reason is that Windows tries to separate program files from newly stored data for security reasons. I recommend you put a shortcut on you Desktop to this location:
"C:\Users\[your user name]\AppData\Local\VirtualStore\Program Files (x86)\QuadToneRIP"
In Windows, use QTR's Curve Creator to alter the profile, not a text editor. The Windows Curve Creator GUI is excellent (though if you're on Win 8 some of the graphing may not work). When you save a profile you've created or altered there, it'll be stored by QTR (actually the Windows OS) under the hidden folder, above. You'll find there will be sub-folders for the different file types and printers.
An *.acv curve is a Photoshop image adjustment curve. While there is a place in QTR where one can import them, I'd avoid this approach. I use PS *.acv curves to control inksets if I'm using the Epson driver to print, but I have not found them useful when I'm printing with QTR.
The place to start is usually to find an existing QTR profile that is for the paper and inkset you're using and see how it works. If you're lucky, re-linearization is all that is needed.
You might find the my write-up of a simple QTR procedure starting at page 11 of http://www.paulroark.com/BW-Info/Eboni-4-Plus.pdf useful. Ignore the inkset. The basic procedures are the same for most inksets. Learning how to set up basic gray partition is key. With respect to printing, I use a custom adjustment curve to account for the differences between my Gray Gamma 2.2 workspace and QTR9;s literally linear printing characteristics, but you can also convert the file's space to QTR's using an ICC that is included in the QTR download (in \bin I believe; needs to be put in your ICC folder -- try right clicking it to install the ICC).
QTR takes some learning, but start simple and you'll find it's a great printing utility.
Good luck,
Paul
