Creasing versus Scoring
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.
In contrast, the Morgana AutoCreaser employs a unique creasing rule and matrix - as illustrated - that eliminates
tearing and, therefore, cracking.

THE FIRST NAME IN DOCUMENT FINISHING SOLUTIONS
The Morgana AutoCreaser – A Revolution in Finishing Technology
Morgana makes a manual creaser called the Docu-Crease
for lower volume users. This is available in 35cm (13.8") and
52cm (20.5") models, each with adjustable backstops to allow
multiple creases.
