Eliminate fibre cracking on your perfect binder

Black coated covers with spines cracked white along every fold — Left, a cover cracking white along an unpressed spine. Right, a cover with its creases pressed before binding.

Fibre cracking on a perfect-bound book shows exactly where the eye goes first: white broken lines along the spine folds and the hinges, straight through the printed colour. Solid coverage, digital print and coated stocks crack worst, and no amount of nursing the nipper fixes it.

The damage happens at one spot in the machine: the cover scoring station, where the cover is scored in the feeder just before it meets the glued block. The steel collars fitted there scratch shallow lines into the printed face, cutting the fibres they should be stretching. The fold then breaks along the damage, and the crack is on the shelf for the life of the book.

This is where it happens, and what replaces it:

The steel scoring discs fitted as standard in a perfect binder's cover scoring section — The metal scores your binder came with: sharp steel edges that cut lines into the printed face. The Quad-Creaser replaces them on the same shafts, and presses all four creases instead.

The Quad-Creaser: four creasing positions with rubber ribs on one assembly — The metal scores your binder came with: sharp steel edges that cut lines into the printed face. The Quad-Creaser replaces them on the same shafts, and presses all four creases instead.

The Quad-Creaser mounts on the cover scoring shafts your binder already has and presses all four creases in one pass. The two spine creases adjust to the book's thickness, job to job. The two hinge creases sit exactly where the cover opens, so the fold happens on a pressed crease and nowhere else.

The creases are pressed by rubber ribs, not scratched by steel. The fibres stretch instead of tearing, the colour stays solid along every fold, and the binder stops being the place where good covers go to crack.
