I have had an Epson 3880 for about a year. I typically print with Photo Black ink but began experimenting with Matte Black and I'm really stuck: Most Matte Black prints lose a tremendous amount of saturation when I print them. It looks kind of like what happens when you lose the black ink channel to a clog. Though a snapshot is always a little hard to interpret for a print, I attached an image to show the difference. It's especially noticeable in the blue of the sky and the brown skin of the model. There is less saturation as well as much less warmth (it's a very warm image).
What's weird is that if I print on plain paper with Matte Black ink, this problem doesn't happen. You can see in the image that the plain paper version is very similar to the Photo Black version with the expected differences between gloss and matte paper. If I could get the Enhanced Matte looking the same way as the Plain paper it would be fine.
I've tried a ton of tests changing profiles, printer output resolution, etc. but nothing seems to work. I'm using the standard Enhanced Matte and Velvet fine art profiles that came from Epson. Please help! It's driving me crazy...
