CITO Abacus: Corrugated Board calculation aid for creasing matrix

Find the optimum creasing matrix

Measure the thickness of compressed material e

The thickness of compressed material of the corrugated board determines the creasing rule height:

Measure the thickness of compressed material (e)

Formula for calculation of creasing channels

designed for material thickness of 0.5 – 1.3 mm
Also available for Cardboard!

The graphic alongside shows a creasing matrix with the creasing rule pressed into the profile. The dimensions used in the calculation aid are as follows:

A= Channel Depth

B= Crease Width

e= Thickness of Compressed Material

d= Creasing rule width

Creasing rule width

A ≈ e

B = (e × 2.0) + d


Formula for calculation of creasing rules

The thickness of compressed material of the corrugated board determines the creasing rule height:

h= Creasing Rule Height

h = 23.80 - e

Creasing Rule Height
