I have an Epson R3000 and have recently begun using Ink Thrift inks. I'm also using Epson Premium Photo Paper Glossy, Epson Ultra Premium Photo Paper Luster, as well as Red River Polar Pearl Metallic. The ink was added to new, unused carts, the supply lines to the print head were purged, and numerous nozzle checks show a clean and uninterrupted pattern. I have used the manufacturer profiles for each of the papers listed in addition to Vermont Photo Inkjet's profiles for the 2880 and 3880 printers. I've also let the printer manage the color profile. My issue is that the photos I've produced since switching to Ink Thrift lack contrast and the colors, particularly blues, lack depth. Areas that should be black appear slightly hazy and dark blues appear light with a purple tint. This is true for all three different papers and is consistent regardless of which profile I use save the printer managed profile. Photos printed in which the printer is allowed to manage the colors are off in the other extreme. Contrast is improved but blues are way over saturated.
My computer is a MacBook Pro Retina and I've tried printing from Aperture, Preview, and Photoshop CS6 again with consistently similar results.
Any suggestions you have are greatly appreciated.
