Sean, do you have your monitor calibrated with a puck? If not you're shootin' in the wind. You may also want to check out ian Lyons web site for photoshop color settings.

Incidently this should have been posted in the printers forum.

I have downloaded the print profiles for the various Epson papers.

I use the Premium Glossy profile and the prints from my 1290 are a good match to the view on the monitor.

Using the print profile has a couple of effects - the image is
darker than the image that is displayed when you view it in the monitor colour space - I use levels to resolve this so it is no big deal.

The bigger problem is the colour shift that occurs - especially
in blue skies - I tweak using various Photoshop tools but the
blue in my blue skies is never quite as true blue as I want it to be.

Are there a set of 'default settings' to apply to ensure that the print is a true representation of the image (in the same way that in the old days of darkroom processing you would make colour corrections for the particular paper type you were using).

Any advice would be most welcome.

As well as monitor profiling, there are two other potential sources of discrepancy:

1. The profile itself is never 100% accurate. Even if it were 100% accurate on the printer that was used to create the profile, the unit you own probably produces slightly different colour for the same RGB value.

2. Monitors have a greater range of saturations than printers do, so they can display colours that cannot be printed. Set your soft preview to the profile you are using to print, then turn on Gamut Warning. Any colours that are displayable on a monitor but not on the printer will be greyed out.

If you have profiled your monitor and if you have followed Ian Lyon's instructions and if the blue is not greyed out by Gamut Warning, then what to do? Create a Curves layer that compensates for the problem, and save that layer for use with all other print jobs done with that profile and paper. For example, if the blue sky has a greenish cast, then create a curve with reduced green in the upper portion of the curve (skies are bright). Write off-line if you need help with this.
