Effective rack card printing sticks to a simple, straight forward formula. Rack cards that catch your eye and quickly get to the point perform best. If people can’t tell what services you are providing, selling or promoting, they are likely to pass right over your offer. Boil your message down to 5 or 6 strong bullet points, include a map, phone number, website, reservation instructions and a discount offer of some sort, and then get out of the way.
