13.1.5.1.2.2.Creasing conditions
The quality of the crease is affected by moisture content, relative humidity of the atmosphere, the thickness of the board as well as creasing conditions.

Creasing conditions include rule thickness, grove width and the pressure exerted during the operation. In addition, board properties also in a complex manner affect the crease quality. Therefore, it is easier to compare creasing qualities by making creases on them under controlled conditions than by measuring each property separately. The PIRA carton board creaser enables creases to be made under controlled conditions.
