Those who have made copies... the copies come out just a shade darker right... because the copy machine picks up on the color of the original pink...
My high-end Xerox at work has a "background masking" option. Turn it on and any light background color is zeroed out.
Another good suggestion is to reduce the original to 95% or so. Not noticeable by the human eye but makes it much easier to laminate and trim and get in your wallet.
FWIW, I copied mine, then signed them with BLUE ink. To anyone looking at it, it looks less like a copy.
