I have a document set up to cmyk preview and proof setup of working cymk us web coated (swop) v2. In this document I'm using a pantone solid coated reflex blue c. If I copy the object with that color to a new document the color drastically changes even though it's the same reflex blue. Notice in the image below, the blue is much richer. I've had three other people with illustrator/print background look at this and we've compared every setting we can think of but can't figure out why it's doing this. Any one have an idea? We need to match the blue on the right in the image below but for the life of us we can't. It always comes out somewhere between the two blues shown. Thanks.
Why is your color mode set to "CMYK" and not "Book Color"?
Drag the reflex blue swatch from the Pantone palette to the swatches palette and choose merge colors.
If you ever tweak a color, which is perfectly fine for getting betting color proofs out of a color proofer, always give it a differentt name (eg: PANTONE Reflex Blue C(cmyk))
