I am using Lightroom 4.1 and an Epson Stylus Pro 3800 printer. Lately, I am having a problem with certain colors, namely shades of blue, that do not match the color on my monitor. Monitor is a Dell Ultrasharp U2410. The reds, greens, and yellows seem to match, but the blues are off. It is a little noticeable in the sky, but mostly when the photo is, say, a royal blue, the print comes out as a noticeably lighter blue.
I'm wondering if this is a printer ink issue - I don't use the printer on a daily basis or even a weekly basis sometimes. The inks have been in the printer about 15 months. Should I try removing and shaking the ink cartridges? Or probably just replace them?
