If you order more than one set of business cards, we expect the same number of artwork files. For example, if you order 4 double sided business cards, we require 8 pieces of artwork, even if you have a common piece of artwork for the back of the cards.
Please submit the artwork in a way that allows the fronts and backs to automatically back up correctly. Either, supply 1 multi page PDF file running in order, i.e. front, back, front, back etc, or submit each card as its own PDF, with one side per page, i.e. a front and a back.
If we are missing any files or if we cannot determine the order, we may unfortunately reject your artwork.
