DIE CREASING AND PERFORATING MACHINES

Creasing is a necessary step if you want to get a clean fold, mainly if you use heavy cartons and cardboards, even in case of laminated leaflets or signatures, offset or digitally printed UV-coated jobs, including on photographic paper.

The “die creasing tecnique” is carried out using the same blade and matrix tools used in a die cutting machine (die cutting blade and countermatrix). It is different from the scoring technique and has been also more frequently used in the past years, thanks to the high-quality results with all types of conditions (materials, paper fiber, treatments) and to its user-friendly characteristics.

The under process job is perfectly registered and then the creasing blade strikes the paper against a matrix (even several times in the same position or with decimal displacements): this allows the adjustment of the depth and width of the creasing line.

With the same “die” mechanical technology, perforations can be done in a sheet of paper or cardboard, either as a continuous or a step perforation. This tecnique can be used to facilitate cutting along previously set lines, alternating it also with continuous or programmable longitudinal circular perforations (“coupon” type perforation).
