Formula for calculation of creasing channels and creasing rules
designed for material thickness of 0.037 – 0.065 inch
Also available for corrugated board!
Legend:
A = crease depth
B = crease width
c = material thickness
d = creasing rule width
g = creasing rule height
The material thickness (c) of the cardboard determines the creasing rule height:
A = c
B = (c x 1.5) + d
g = f – c
f = 0.937 inch
(c) Results for material thickness 0.016 inch
Optimum values are backed with yellow.
| (A) | Channel Depth: | 0.016 inch |
| (B) | Creasing Channel Width with Creasing Rule of 0.028 inch / 2 pt: | 0.051 inch |
| (g) | Creasing Rule Height: | 0.921 inch |
In order to optimize the quality of the creasing, you choose the next smaller channel width possible when creasing with the grain.
You will find the size 0.4 × 1.3 mm at CITO
