I have an Epson 895 printer. I click on printer, select properties and then custom, advanced.
In this mode one can change many settings:
gamma, brightness, contrast, saturation and levels of cyan, magenta and yellow. Experiment to find a good brightness and colour balance; these can be pre-set for future use.
I have no idea if your Epson printer software has a similar option, but its worth having a look.
ps: I also use compatible inks from Choice, and have no problem.
