I used the Luminos Silver on an EX and had similar problems. The cause in my case was that the darker magenta was a little too strong and the light magenta was okay. Correcting one of the magentas threw the other one off. I finally cured it by going to the green layer and fooling with the green black point, which boosted the green just in the shadows. By trial and error, I was able to get a continuous gray scale. But it was a pain, so I switched to the generations inks, which can be corrected with the sliders in the Epson print driver. In the end I got better results, plus the benefits of a pigment-based inkset. You may be able to correct the Luminos inkset with a custom profile, but I saved myself the trouble and expense. I can get great grayscale prints with no hassle. An added benefit is being able to print from any program -- not just Photoshop. Note: I believe it's much easier to correct for variations in a 4-color inkset than in a 6-color inkset. In a 4-color set, you have only one of each color, but in the 6-color sets, you have two magentas and two cyans. Even with a profile, you may still have crossover problems when working with grayscale, as the tonal range shifts between the darker and lighter versions of the same color. So, as to your request on how to correct this: Dump the Luminos inks and get the Generations. I have heard that the MIS inks are also pretty close to the Epson inks, but I have no experience with them. I am still using the Epson OEM black ink. I just use the color Generations inks. Also, experiment with the different paper settings in the Epson driver. I found that some of my images look better with the Plain Paper setting (720 dpi) and some look better with the Photo Quality Inkjet Paper setting. Don't be afraid to waste some paper and ink while experimenting. The more prints you make, the more you will learn. There is no substitute for experience.
