Traditional rotary scoring machines use circular blades that are in constant motion as the stock passes through them. This creates a ploughing action that actually cuts through the top fibres of the paper or card in order to create a score. Inevitably this weakens the paper and encourages cracking.
Before Morgana launched the AutoCreaser, printers and finishers faced with the problem of cracking media had two choices.
1. The first was to use a platen or cylinder press – effective, but very slow to set up and demanding high skill levels.
2. The second involved the use of rotary scoring, which almost inevitably damages the material, resulting in white show through on the spine of the folded document.

Creasing rule and matrix
The Morgana products use a creasing rule and matrix action that applies several tonnes of pressure to weaken the fibres of the paper. However, unlike a rotary scorer this does not tear the surface, so there is no white show-through, even when the fold is made in an area of solid colour.
Creasing blades can easily be changed and the operating action can be reversed for inverse creasing.
To eliminate cracking of the substrate the AutoCreaser employs a technique by which the fibres are embossed to weaken them. The creasing mechanism consists of a male creasing rule and a female matrix that come together to perform a superb crease.
By embossing the paper in this way, cracking is eliminated.
In summary, the creasing rule and matrix ensures:
• Fibres are compressed, not cut
• 6 tonnes of pressure applied
• The crease is even across the sheet
• Lifetime warranty on the matrix

Innovative folding technology
The DigiFold Pro and AutoFold Pro both use Morgana’s patented “flying knife” technology.
The flying knife allows delicate digital stocks, cross-grained materials and heavy weight stocks to be folded without any of the scratching and marking caused with conventional folders.
Users benefit from the simplicity of the system which will give unparalleled performance and longevity.
