Creasing is one of post-printing processes when a special path is created on paper or cardboard along the entire length of a desired fold with the help of blunt rotary wheels. The dented path prepares material for bending/folding and makes it easier, especially when this operation is applied to products made from heavy stock paper (with density of 170 g/m2 and more).
Creasing ensures accurate folding without cracking or breaking even for thick cardboard.
The method of creasing has a number of significant benefits:
- the printed product easily takes necessary shape;
- increase of material endurance in the folding points;
- even printed cardboard has no cracking along the folds;
- no cracking or splitting of layers occur in a printed product when bent or folded.
