thanks so much! Yes you were right about the curves. Just wanted to verify, do you have to covert to greyscale? Gamma is 2.2 correct? The HPR profile is for hahnemuhle photo rag> How do you like the Canson Rag photo, and bfk rives? Printing for a small gallery show... poetic street photography in the Amazon ( I know a little oxymoron). After making 1-2 test prints not seeing a whole lot of difference in qtr vs regular printing maybe a little more warmer
Thanks for all the advice!!!!!!!!

Hi Calvin,
When you ran the Install3880.command file did it open a window in Terminal and run through a bunch of instructions? If so, then you should be good to go. If not, then something is wrong.
Assuming the installation is complete, you should see sets of 4 profiles to produce cool, neutral, warm, and sepia tones for a variety of papers on the Curve dropdown lists. Keep things simple to start with and just use one curve. Multiple curves can be used to produce intermediate tones (e.g. if sepia is too warm and warm not warm enough you can use both and adjust the ratio to get what you like.) Multiple curves can also be used to produce split-tone effects. There are many possibilities.
Regarding papers, I think prbaryta is Hahnemuhle Photo Rag Baryta. There might be a list of abbreviations in Roy’s Tutorial. If not, just ask here - someone will know.
If you haven’t read it yet, I highly recommend Amadou Diallo’s QTR Workflow article available in pdf format on the QTR download page.
My personal feeling is that many new users make QTR much more complicated than necessary by thinking they have to make custom profiles right from the beginning. Learn to use the included profiles first, then move on to custom profiles if you need them. I currently print with a 3800 and only use matte papers such as Moab Entrada Natural and several of the Canson art papers. There is now a profile for the Entrada, but there wasn’t when I began using it, so I used the HPR profile with excellent results. I now use the HPR profile with Canson Rag Photo and BFK Rives and don’t feel the need to customize them.
I do make custom profiles for producing digital negatives for contact printing in the darkroom using Platinum/Palladium and other historical processes, but that’s a whole other can-of-worms.
Let us know if the profiles are there in the Curve fields and good luck with your printing.
Oh, and do use Print Tool since you are on a Mac with OSX more recent than 10.5.
Cheers,Keith

Thanks for the reply! Ok will try that tonight. Yes I opened up the 3880 folder and clicked on the install curve app. For the 3 curves option, I remember seeing that, do you only pick one of the curves? also not sure what the abbreviation for some of the papers... prbaryta? Will have to recheck tonight
Thanks!!!Calvin

Hi Calvin,
You say you “clicked on the folder …”. Did you also run the installation file named Install3880.command?
Where are you looking for the curves? They are not the same as icc profiles and do not appear in the Printer Profile list under Color Management. Rather, click on Print Settings then select QuadToneRIP in the dropdown menu below Paper Size. You should then see fields for selecting up to 3 curves. This is where the QTR curves (profiles) are listed.
I can’t speak from experience regarding your particular paper choice since I don’t use either, but it is often possible to get excellent results using one of the supplied profiles for a similar paper. Even if they are not perfect they will be a good starting point for creating custom profiles.
BTW - the terms profile and curve are synonymous in QTR.
Regards, Keith

Hello!!!!
I have just tried to install quadtone rip and the print tool. I am using a mac , 10.9. With an Epson 3880. I think I installed both properly. I then clicked on the folder to install some of the preset curves for the 3880, but when I go to try and print using either photoshop or print tool, I can't seem to find the profiles. All that comes up for quadtone I think is gray matte and glossy. any help??
Also I plan to try and use Epson exhibition fiber, and read somewhere maybe use the preset for silver rag. Any experience doing this? any where to download this specific profile?
Thanks!!!!!!!!!!!
