At the February meeting there was some talk about where to get colour profiled printing done at reasonable prices.
The first step in this is to colour profile your monitor there are a couple of ways that you can do this
Colour Profiling Hardware
There are a couple of main companies that do profiling hardware
Both companies provide hardware that will do a good job profiling and maintaining an accurate colour profile of your monitor under windows or Mac OS X.
Colour Profiling Software
I personally haven’t used any manual colour calibration but Dry Creek Photo that does the colour profiles for Costco has this page that explains a manual procedure. And they also have a large learning section located here that is a good primer for colour management.
The next step is to download the colour profiles for the Costco closest to you all the profiles are available here.
The final piece of the puzzle is installing and using the colour profiles. Again dry creek has a great page with a great instructions on how to do this.
I did mis-speak at the meeting about Apertures support for outputting colour profiled images. I just tested this and it does actually convert exactly the same as Photoshop does so anyone using aperture can screen proof and convert correctly.
