Folds can be a make-or-break deal when it comes to your print job. An inaccurate fold can also slow down your turn-around time if we have to send the file back to you. A measurement as small as 1/16″ can make a big difference. For example panels sizes are different on a standard trifold brochure than a comparably sized Z-fold brochure.
