Thread sewing is the ultimate bind, it opens flatter than a perfect bound book and there is greater pull page security, standing up to greater usage.
Folded sections should allow for a 10mm lap low folio. Papers below 80 gsm are not recommended, all four page sections must be wrapped. Staggered spine collating should be printed onto the spine during the print row to assist us with correct gathering sequence.
Spines will have no mill off and should not be perforated. 2PP tip ins cannot be sewn. Minimum trim allowance is 5mm head and tail.
Max size: 340x305mm
Minimum size: 150x110mm
