I have both an epson 7900 pro and a 3880. I am using cone ink sets in both. I notice that the reds in the 3880 are deeper and richer than on the 7900. The 7900 has almost an orange tinge to the reds. I don’t know how long this has been the case as I generally don’t print he same images on both printers and compare them side by side. I really noticed it when I started printing a test image on both machines on a regular basis to ensure that the inks would keep flowing. I have used a colormunki to profile paper on the 7900 and still get the same results. This is most noticeable if I print a solid red patch R255.G0.B0. my colormunki spot reading is R220G63 B51 a Vivid redidish orange.
My nozzle checks print cleanly and crisply. Even so I have done a number of power cleans with no change.
Is this a difference that I should expect as a normal variation between ink sets and printers?
Is this a problem with the first formulation of the 7900 HDR inks?
Thanks for your advice
