CITO Abacus online for Corrugated Board (inch)


Formula for calculation of creasing channels and creasing rules
designed for material thickness of 0.020 – 0.051 inch
Also available for cardboard!


A = crease depth
B = crease width
c = material thickness
d = creasing rule width

g = creasing rule height

e = thickness of compressed material

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

A = e
B = (e x 2.0) + d
g = f – e
f  = 0.937 inch

(e) Results for compressed material thickness 0.031 inch

Optimum values are backed with yellow.
(A) Channel Depth: 0.031 inch
(B) Creasing Channel Width with Creasing Rule of 0.028 inch / 2 pt: 0.091 inch
(B) Creasing Channel Width with Creasing Rule of 0.041 inch / 3 pt: 0.106 inch
(g) Creasing Rule Height: 0.906 inch

You will find the size 0.8 × 2.7 mm at CITO
