I am using CS5 on a Macbook and printing on an Epson Sylus Photo R2400. I recently upgraded to OSX 10.7 (from 10.58 if this matters). When I compare a photo that I printed before the upgrade with one printed after the upgrade (using the same paper and profile and the file has not been edited between printings), the one printed in 10.7 has a slight magenta cast (the original print has pastel greenish blues; the one printed from 10.7 is more greyish violet). The original print matches the calibrated monitor better as well. I am using photoshop to manage colors, and, as far as I can tell with the new driver, printer color management is turned off (this seems to happen when the settings are selected in the photoshop print window).
I have read that there were potential issues with drivers, but I have cleaned out the Epson folder in my system library, reset the printing system, and reloaded the printer with newly downloaded drivers from Epson. None of this seems to change the output.
It may be possible that the new Epson driver yields different color from the same file/profile combination, but this strikes me as unlikely.
It may also be that there was some nozzle clogging in the original prints that, once cleared, has resulted in the color shift, but the number of consistent prints and timing of the shift makes this unlikely as well.
I am tempted to get a custom profile for the printer to address the match issue, but if there is some software glitch that is causing the shift, am not sure this is the right solution either.
Does anyone have any advice as to how to resolve this issue?
