The company I work for typically uses VistaPrint for their printing needs. I recently designed a letterhead in Illustrator, printed it out off my Canon Pixma (which seems to have good color), and checked it with what I was looking at on my computer screen. Everything looked pretty good - I used a blue color that we have as part of our corporate ID (so, it's the same cmyk %'s every time). We got the letterhead back from VistaPrint, and they were tremendously darker and the blue had more of a purplish tint to it than what I printed off or what's on my screen, which is pretty well calibrated. Any idea of what I could have done wrong, or does vistaprint just suck?
