Shadows in Illustrator dark, muddy, not smooth gradients
Hello all,
I have an issue that no amount of messing with color settings seems to be able to fix. Attached are two screenshots. On the candle graphic, the shading underneath the flames is smooth and evenly colored. This is on my clients end. On my end, when I open the file, and when I return it to her, the candle looks like the screenshot where the shading beneath the flames is a muddy black.
Please help...I've tried everything, reinstalling the program, rebuilding the entire document, everything....I don't know if this is just an issue of my MacBook not being able to handle these sorts of graphics or not.
