I am just now in the process of adapting a lot pictures for print in a book, so I am fighting the same battle as you are, even if the profile I am using (Fogra CMYK), is a bit different from the profiles that come with your Epson.
I have done the necessary mechanics: monitor calibration and monitor at 90 luminance. However, there still remains the HUGE DIFFERENCE between the picture's appearance (in all its glory) on the screen and the comparatively poor representation you will get in print, due to the different manners of illumination (direct vs. indirect).
I have found the following steps to be useful in getting the print as close as possible to my vision, as exhibited on the screen.
1 After finalizing the picture to your full satisfaction, turn on the Photoshop function View/Proof Setup/Custom. Once there, put in the profile for your printer and paper. Thereafter, check option "Black point compensation". Additionally, and THIS IS VERY IMPORTANT, check the option "Simulate Paper Color". The last named option makes Photoshop diminish the contrast of the screen so that i equalizes, more or less, the contrast range of your printing paper, as printed upon by your Epson printer.
2 Now pushing buttons Command+Y (on the Mac) will toggle the proofing view on and off. Do this several times and you will be amazed by the difference between the two views. With the proofing view on, the print in general appears (1) darker, (2) less contrasty and (3) less saturated in specific colors, mostly saturated red and blue (sky for instance).
3 Now change the file so that the proofing version gets as close as possible to the original version. I found that this usually takes two simple operations (could be combined in one). (a) Choose adjustment layer "Curves" and check option "Lighter". Apply this option at 25% Opacity; (b) Choose again adjustment layer "Curves" and check option "Linear Contrast". Apply this option at 100% Opacity. These two adjustments put you very close to the best possible adaption.
4 Adjust minor details in picture as you find necessary. This could involve, for instance, adjusting colors out of printing range (tint or saturation) and increasing local contrast in deep shadows, which sometimes looks "washy" even with the adjustments in step 3.
Andrew Rodney has done us an excellent service with his article "Why are my prints to dark". However, he does not go into detail on what I am talking about here. That you have to force yourself to make the file a bit lighter and contrasty to get it closer, in print, to what you perceive on the screen.
I hope this helps!
