Question

Will thick paper crack when I fold it?

Answer

Yes, heavier stocks can crack along a fold if they are not scored first. Scoring presses a shallow groove into the sheet so the fibers bend cleanly instead of splitting or flaking.

  • Stocks around 12pt and up usually need scoring before folding
  • Coated and laminated papers crack more easily than uncoated, so score them
  • Always score first, then fold, to avoid a rough or peeling edge
  • Mark your fold lines clearly in the print file so the crease lands in the right place
