I've read your comments on Colorvision monitor calibrators for some time, and I recently bought the Spyder2express. The improvement, especially for my MacBook Pro display, is remarkable.
But, when I print to an Epson Photo R300, the results are noticeably darker and warmer than what I see on screen. I'm using Epson inks and Premium Glossy Photo paper, with printer color management shut off, and the right paper selected. The difference is not just to my eyes; a light gray wall that looks neutral to me, AND that Photoshop reads as neutral prints with a visible color cast.
For comparison I printed the same file on an Epson Photo 820, and got a much closer match, even with remanufactured ink cartridges. Frustrating, since it uses the small all-in-one color cartridge.
I'm thinking that I'm seeing individual printer variation with the R300. Since I didn't get the Colorvision printer adjustment software, or the much more expensive hardware, can you suggest any way to tweak the printer?
