Scoring Tools
Purpose of scoring:
To create a hinge-type zone to aid the subsequent crossfold:
-
if the sheet cannot be perforated for functional reasons
-
if stiff or coated papers are handled
-
if the grain of paper is going the wrong way
Scoring (1) is done with a male scoring wheel (2) and a female counterpart (3).
A groove is pressed into the paper when it passes between the tools.
The texture of the material remains intact.
