I received my 1000 business cards the other day and was disappointed that the 'truebluedot' is more like a true off-purple. The printer didn't do anything wrong per say, but simply used inks that metamerize under incandescent & fluorescent lights. I'll have to print them again locally with a screened Pantone and black ink.
Technical color problems are part of the game, but ohhh the delight of handing out a clever and excellent business card! Here is a site that features a whole slew of fantastic designs.
