QTR Profiles and 7890 for K7

My colleague and I are ramping-up a 7890 with a K7 ink set (warm-neutral)

We just downloaded QTR for MAC, from Roy’s site,and two issues have occurred:

  1. I see no profiles for the 7890 / K7. I see the profiles for UC inks and this machine. I also saw many other Epson printer models for K7, but again, not my 7890.

I tried a few other profile options thinking they may be the same, but the message I receive is that the download of profiles does not recognize another printer model. So none of the 4880s downloaded, etc etc.

  1. I thought I could figure this out by opening up the Print Tool, but in Mac, I can’t seem to open up the print tool and main interface? Yet, I see QTR folders and files in the application folder.

Can you shed some light?

Roy Harrington of the QTR software has explained this issue, thank you! Here it is for other K7 7890 useres: The K7 profiles are compatible for all the big pro printers.

“Go into the 7880-9880-K7 folder. Just rename the Install7880-K7.command
script to Install7890-K7.command – then you can run it and it will find the
printer and curves.”

We also have instructions for setting up a 7890/9890 with Piezography, including the curves and instillation instructions, here: http://www.piezography.com/PiezoPress/technical-support/epson-7890-9890-installation/

Dana, your 7890 QTR profiles are awesome, thank you. Regarding MPS profiles, does anyone there also have the Hahnemule Photo Rag Pearl and Canson’s Plantine Fiber? Or do you not reccomend those papers for the K7 glossy process?


We have some glossy curves available (which are custom curves we’ve made over the years for different customers, and have been confirmed to work well before making available for others to use), here: http://www.inkjetmall.com/tech/content.php?158-Piezography-K7-Additional-Curve-Resource

This page includes information about what printer models can use the same curves, and how to install new curves. 8-color K3 printer models should use “3800/3880” glossy curves for the best results, as these curves have a slightly lower ink limit for optimal gloss compatibility. The 3800/3880 MPS curve download does include a few curves for Canson Platine Fibre Rag, but not Photo Rag Pearl, though you can try the Photo Rag Pearl curve in the 4800 or 7800/9800 folders (but these have high ink limits, so may not produce as good of results as the 38xx curves). If you’d like, we can certainly make custom curves specific to your exact printer, ink, paper and computer setup, which will give you the very best results for your system.

I hope this helps, best regards and happy printing~ Dana :slight_smile:
