FIG 1-26
1-26 KNIFE PRESSURE TEST PATTERN
Peel out the rectangle and inspect the media backing.
The knife depth is set correctly when the test pattern cuts completely through the vinyl,
the vinyl is removed and the blade tip visibly scratched the front side of the media
backing. The blade should never cut through the backing; just slightly scratch the
silicon coating and first few fibres of the backing material.
Because the knife pressure setting depends on the thickness and type of media to be
cut, adjusting the knife pressure will require some practice. In general, the knife depth
must be increased when using thicker types of vinyl and decreased when using thinner
types of vinyl.
