FIG 1-18
1-18 PEELED KNIFE PRESSURE TEST PATTERN
The knife depth is set correctly when the test pattern is cut 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 the
first few fibres of the backing material.
Because the knife pressure setting depends on the thickness and the type of the 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.
ATTENTION: After setting the cutting depth and/or the knife pressure, perform a
thorough visual check of the knife blade, protruding from the knife holder and test
the cutting results on a scrap of vinyl media.
ATTENTION: Do not operate the cutter if the knife blade cuts through the media
backing, as this will seriously damage the cutter's rubber cutting strip and the
knife.
ATTENTION: For most vinyl cutting operations, the knife blade tip will be barely
visible at the bottom of the knife tool. If the knife blade tip is visible, then the
cutting depth must be readjusted. To prevent damage to the cutter, check the
depth of the knife blade tip and the quality of the cut each time you load a different
type of vinyl into the cutter.
