QTR-Quadtone RIP

HI, New to this group because I’ve decided to try QTR instead of Imageprint. ($$$) I’ve been using Epson printers for years and do the majority of my pronging in black and white,
I find the paper choices in QTR somewhat limited. I use Epson Ultra Premium Photo Paper Luster primarily because it is so close to The Epson Exhibition paper I love for my final prints.
There does not seem to be a profile for the Luster paper under the R2400 heading. I tried a few other profilings that were disastrous.
Any thoughts?

Thanks in advance.

At the risk of being a pendant, it will make things clearer if the OP refers to the QTR configuration files as curves rather than profiles. The term profiles usually refers to ICC profiles and it is possible to generate ICC profiles using QTR, and to print to QTR using ICCs (easier to do on a Mac using Print Tool that it is on Win). A curve is a specification of how much ink is laid down by QTR for a given paper and print combination.

As Walker said on the IJM forum recently:

https://community.inkjetmall.com/t/epson-3880-piezography-pro-paper-curves-for-epson-and-other-papers/6775/2

there aren't that many different papers in practice, and all you have to do is find a close match among the available curves.

Best guess is to make a profile by taking one which may be similar and editing it. You can take the qtr profile road or the icc road, it depends whether you prefer to work in a color managed environment or not.

With the qtr you can linearize curves for the visual density and adding toners for the hue by changing small percentages of C,M,Y inks. With the more sophisticated icc approach you need a densitometer or a spectrophotometer to make the charts readings and convert them to icc profile.

Personally I find the qtr approach far easier and direct.

Hope this helps
