Hi:  for years i have been lucky no problems....   Then one day i cheated and did not follow old established rules.   I downloaded a printer update from epson europe.    Suddenly all images were dark ...  Tried everything.   Then back to reality....reviewed what changes i made...?....

 I usually always delete all printer software before installing an update.  I had missed that for the first time.  Why.   Tried to cheat very picky and time consuming task...

Then i found on us epson download site software tailored to delete all.  I used it

Then downloaded updated driver.    All is now well again

Rule 1.      for at least all epson pro printers clean up and delete epson software before you update drivers.(this includes the root library)
Rule 2.   Never accept apple update to your printer environment.   Get it all yourself.

Cheers. Elo

Could it be possible that the inks are old and have begun to deteriorate a little, that the some of print head nozzles might be dirty or clogged despite maintenance cleanings, or that either in the image editing software or the printer driver, the color intent setting has accidentally changed or is inappropriate.  While I suppose that the Spyder could be out of spec, it seems to me that the problem lies more in the printing and the printer, its inking levels, and maybe even spray patterns.  However, as I said, this is just a conjecture on my part.  I do know that as dye based inks get older, they get darker.

This is consistent across three printer profiles - the canned Epson profile for Premium Luster, my own profile made with a SpyderPRINT package, and a custom profile I had made by Michael Gordon of "GreatPrinterProfiles".
