Tips for Oversized, Miniature and Signature Folding Projects
Map folding projects like this one
require special planning to execute properly.
Inaccurate folding can hinder the effectiveness of an otherwise superbly printed project. Folding makes a world of difference in your product’s appearance and functionality, and simply understanding important layout, planning and production guidelines can help you avoid most potential problems that may occur during the folding process. Read on for Schultz Bindery’s tips for making sure your next folding project goes smoothly.
Oversized Folding – Account for Creep
Oversized map projects typically involve several right-angle folds, so they require special layout considerations. For example, the layout must account for folding “creep,” which refers to the shift in image area that occurs when multiple folds push out. The thickness of your stock and the number of folds in your oversize project will dictate how your layout compensates for creep.
Miniature Folding – Make Sure Your Finished Piece Lays Flat
Miniature folding often entails fitting the same amount of information as a normal-size piece into a much smaller insert. But more folds create more panels, which often results in a finished piece that simply won’t stay closed. Experienced miniature folding providers can employ a number of solutions to this problem:
Glue - A tiny glue dot placed inside the edge of an outer panel is often enough to hold the piece shut. For best adhesion, both glued surfaces should be free of aqueous coatings. Always check with your bindery regarding coating decisions or options.
Moisture - By adding moisture at the final fold, your bindery can soften and relax the paper fibers to create a "memory" of the folded, lay-flat position once the paper dries. Keep in mind that this technique won't have an effect on pieces with high-gloss sheet surfaces or coatings.
RTA Fold- A right-turn angle (RTA) fold usually ends with a knife fold and the application of glue to create a finished product without any open edges.
If your pieces must lay flat, involve your folding partner as early as possible to identify the most effective and economical solution available for your application.
Signature Folding – Perforations and Parallel Folds
Perforations are often placed on the spines of signatures to help release excess air and relieve wrinkling once they're folded. While signature perforations are fine for perfect binding projects, they should not be placed on signatures destined for saddle stitching. Often, the stitches will simply break right through the weakened points in a perforated spine.
If your book project includes critical cross-over text, images or charts, it's best to use parallel folds for your signatures as opposed to right-angle folds. If your right-angle folds are misaligned by even 1/32", crossovers will be misaligned by at least 1/16" - which is objectionable.
