“Cracked” Folds

Thick paper does not fold as easily as thin paper. When thicker paper—cover stock, for example—gets folded, the fibers in the paper bend and snap. On most paper, this bending and snapping is not noticeable… unless there is printing along the fold. When printing is on the fold, white colored “cracks” can appear. This is especially noticeable with dark ink (such as black).

To prevent cracking, we suggest the following:

  • Try to design pieces so that there is no ink or color along where the fold goes.
  • If you are using heavy stock, and there is ink or color on the fold, have your pieces scored. Scoring helps keep the fold neat.
  • If you are having problems with cracking on a heavy stock, consider using a lighter stock.
