I struggled with color management all day (or you might say, for years now). | |
Here's what I did: | |
Read http://www.viget.com/inspire/the-mysterious-save-for-web-color-shift/. | |
He's exactly right. Doesn't cover Illustrator, though. Here's what I figured | |
out: | |
Calibrate your monitor. I use Huey Pro. I use a color temperature of D65 and a | |
Gamma of 2.2. | |
Look at your EPS. Try to figure out what profile was used to create it. Before | |
you open anything, in Illustrator set that to be the working color space and | |
check everything with regards to prompting. | |
Open the EPS (which has no profile) and convert it to what was used to create | |
it (in my case it was Adobe RGB). Save as PSD or if you have slices, save them | |
as JPEGs at 100% quality and embed ICC profile but don't convert to sRGB (on | |
the little flyout in Save for Web). | |
Set Photoshop up with your monitor profile and have it prompt you. Open your | |
export/save-for-web from Illustrator in Photoshop. Convert to the working | |
space (your monitor profile). Save for web in the desired format. | |
Probably could have also done the Monitor Color preset in Illustrator, but | |
then it wouldn't have asked me to assign a profile when it was missing. I | |
probably could have assigned it after opening. | |
Never in this process did I preview proof colors. In Illustrator it would have | |
been wrong and in Photoshop it should have been the same since my working | |
space was the monitor's profile. | |
At the end, open your raster thumbnail of the EPS (if you got one from | |
iStockPhoto) in Preview and compare it to your final output in Firefox 3.0 | |
(you can enable ICC profiles in 3.0 and it might be by default in 3.5, but | |
don't). They should almost match even though Preview is ICC-aware and is | |
reading a file with an embedded ICC profile and Firefox is ICC-ignorant and is | |
reading a file with no embedded profile. |
