Zig-zag folded covers on perfect bound books are becoming more common. The vast majority of these covers are heavier stocks; usually 12 point or thicker. The fold is short at the face, because if the folded cover is flush, the binding price goes through the roof! The reason for this is that the finished book cannot be trimmed because trimming would cut off the fold on the panel. When the folded cover is flush, the book without the cover must be bound and trimmed at the face and then passed through the binder again to apply the cover! We can now produce books with three or four or five panel covers! I am continually hearing the market…give me something different…something memorable…something that engages the customer…something that sells more effectively.
One of the answers to these constant questions is “multiple panels” perfect bound book covers.
