A good cut for the custom paper box should be clean and free from loose ﬁbres and particles. This will give accurate and clean edges and avoid contamination problems during further processing of the paperboard or in the packaging operation.
To achieve clean, debris-free edges, it is important to have the correct cutting conditions. Due to its strength, toughness, and density, paperboard requires sharp, well-adjusted knives and good control of the die-cutting machine. The high force required to cut through has to be well controlled to minimise what is called the "overshoot" of the moving die. Otherwise the knives will hit the counter plate too hard which will quickly damage the knives and degrade the quality of the cut edges.

Creasing is an operation which facilitates the folding operation of the custom paper box. During creasing, the paperboard is weakened along well deﬁned folding lines, which then act as hinges for folding packaging boxes. It is very difficult to fold paperboard with a good result without creasing.
The creasing rules are ﬁtted into the die. When performing the creasing operation, the die reciprocates up and down towards the paperboard, which is placed on the make-ready. After one cycle the creased paperboard sheet is removed and a new one is fed into the machine.
The paperboard is creased by being pressed into a channel or groove in the make-ready. The forces created deform the paperboard in a predetermined way and the deformation is permanent. The result is a reduction in the bending resistance of the crease. The paperboard is therefore weaker along the crease than elsewhere.
