Sadly I'm in the same boat as Dave.
I wrongly assumed you all had ICC profiles for the inks you sell like you do for the Cone inks. I feel a little duped to be honest (I read and re-read your site many times). I even bought 2 Cone inks initially thinking they were better but then I found the Inkthrift and decided to get those.
These Inkthrift inks are so dark and over saturated. I have a fully calibrated system but don't have icc profiles for these inks. I have an Epson 3800. I was sent vivid magenta and light vivid magenta and my printer normally doesn't have those colors? I sent in a request for help thinking you all had sent the wrong inks but alas those are the inks even though they are the wrong ones.
Here is a screen comparison versus 1. epson regular ink on left (please notice it's calibrated almost dead on) 2. Inkthrift inks on the right
Here they are in better light just the prints.
These are SOOO different that I don't understand how you can sell these inks WITHOUT a profile and expect people to be happy. I don't have a calibration profiling rig and to be honest all the science I see on your site I felt pretty good not having one. But this is really disappointing.
How do you fix this?
