Tips for Best PUR Binding Results

  • Allow a minimum 1/8" head, tail and face trim on inside text pages.
  • Allow 1/16" to 1/8" for "grind" on spine edge of inside text pages.
  • On the cover, leave an extra 1/8" at the head and an extra 1/4" at the tail of the untrimmed folded signatures. Very important!
  • Cover around back to front minimum overall 8 1/2".
  • Make certain grain direction of cover is parallel to the spine for a more durable bind.
  • Consult with RGS when designing your layout.
  • Remember, PUR has a 24 hour curing time requirement.
