Creasing machines: When paper or card is manufactured, the fibres in the material lay in all directions. When folded by hand (or on thicker stocks paper folding machine) the fibers fold in various directions which break the surface, resulting into a messy unprofessional finish (aka cracking). Moreover, when printing on coloured stock this will also show through the ink. Using a creasing machine prevents these problems from occurring. Creasing machines compress the fibers in the material forming a u shaped channel. The material can now be folded without cracking. Perforating machine: A perfortion is a process that creates a line of tiny holes in the paper or card. These holes act to create a join-point in the paper, strong enough to hold the material together but weak enough, so that should a deliberate pulling pressure be applied, the material will seperate in a clean straight cut. Typical applications for perforating included, tear off cheques, vouchers etc. The most common perforation sizes are 7 per inch, 11 per inch and 17 per inch aka microperf Multi Function creaser/perforators: A machine that does both of the above, these tends to happen by a simple swap from crease to perforation blade or vis versa. Some multi / dual purpose models now come with splitting blades for cutting material as well as perfing / creasing it, adding additional value for money.
Bar vs wheels creasing and perforating. This is the method used by the machine to implement the crease or perforation onto the material. Both methods use a channel underneath the paper/card to push down into. On the bar method a blade comes down much like a guillotine, whereas with the wheel method the stock is fed through the machine using rubber wheels with a spinning metal wheel creating the desired finish.
