When planning projects for roll folding, properly-sized panels can make the difference between an average-looking product and a great-looking one. While the shape of individual panels may look similar, often they need to be sized differently to allow for shingling, wraparound, washout (creep) and push-out. Properly-sized panels also reduce waste and improve running speeds on folding machinery. Here are a few planning tips to be sure your roll folding projects look their best:
What's a Roll Fold?
 An over & over fold (a.k.a. "roll" or "barrel" fold) is a common folding sequence whereby each succeeding panel reveals another part of the message as the piece is opened. If creatively used, over & over folds can pique a lot of interest. Common applications include self mailers, brochures, pocket schedules for transportation and sporting events, credit card applications, financial prospectuses and more.
Panel Sizing Tips
Each panel of a roll-folded piece must be undersized to compensate for the cumulative thickness of each panel. This is important to consider during project design, as correctly-designed panels will allow your bindery to fold the piece on the color breaks rather than alongside them.
For text-weight stocks, the outer two panels should be remain final size, with each succeeding interior panel decreasing by 3/32". In addition, the last panel need only be 1/16" smaller than the preceding one. For projects on cover-weight stock, each panel should decrease by 1/8" as opposed to 3/32" for text-weight stock.
