What we solve
It's late on a Friday afternoon and the bindery manager is starting to panic: his best operator still can't get a clean score on a four-page brochure after two hours of trying. The stock is printed solid black with the grain running against the fold, and no matter what he does, it cracks.
During folding, enormous stress is placed on the stock as it's forced through the plates. On UV-varnished, gloss-finished or toner-based digital work the outer coat simply splits and breaks, fibre cracking, and the heavier the coating, the worse it gets. The hard truth is that the scoring device supplied with your folding machine was never designed to stop it.

How the Tri-Creaser works
Where a steel blade crushes the fibres, the Tri-Creaser uses a softer, patented rubber creasing rib that penetrates the stock up to three times deeper without splitting or damaging it. Instead of a sharp V-shaped score, it forms a rounded U-shaped crease that spreads the pressure evenly across the whole fold, forcing the material into the shape of the matching female channel.
It works the way a letterpress cylinder does, applying the crease directly on top of the area prone to cracking (the outside of the fold) and gently pushing the fibres back inside. The result is a perfectly formed bead, no cracking on the outside, and a cylinder-quality crease produced inline on your folding machine.
Good creasing needs the right width and depth for every stock, a setting for 100gsm paper falls a long way short on 350gsm cover. The Tri-Creaser has up to 8 pre-set crease options built in, so there's no guesswork. The operator simply matches a colour-coded creasing rib to its dot-coded female channel; all the thinking is already done. Changing from one crease setting to another takes seconds, and even your least experienced operator becomes an instant creasing expert.
Tech-ni-Fold borrowed the proven reverse-crease method from letterpress cylinder creasing: the crease is applied directly on top of the area prone to cracking, the outside of the fold, gently pushing the fibres back inside. A perfect bead forms on the inside, highlighted when the product is reopened, proving the crease has penetrated right through. It was the first time the cylinder-creasing method had been replicated inline on a folding machine.
The patented split creasing-rib technology lets the operator snap the right setting into the male hub without removing the device from the folding machine's exit shafts, so a change of crease style takes seconds and set-up times drop dramatically.
