Each roll of media
will have a recommended value to add or subtract from the default baseline
values used for Knife Pressure and Knife Stretch Factor. These values are listed below and printed
on a label attached to the inside of the core.

Knife Stretch Factor
can be increased or decreased to compensate for different feed thicknesses
and textures of media. Thickness and texture can affect the feed speed of the media usually causing
it to feed more slowly than the baseline media (High Gloss Paper). This will cause the height/length
of your cut to be shorter. If you find that your cut height/length is longer or shorter than the height
specified in the PTCreate software, you may need to increase or decrease the stretch factor.
Increasing this value with create a longer cut. Decreasing it will create a shorter cut.
Adjusting Knife Pressure over time.
Eventually, the knife blade will begin to wear and require more cut pressure to cut at the same
depth as when it was brand new and sharper. Therefore, you may need to add cut pressure when
cutting any media even the High Gloss Paper.
To determine if cut pressure needs to be increased or decreased, follow these steps.
1.
Print and Cut 1 copy and then attempt to peel the label from the liner.
2.
Check for tear. If the label tears when you remove it, you will need to increase the cut
pressure. Increase pressure in small increments to avoid over compensating and cutting
through the liner.
3.
Check the liner. Once you peel up the label, check the liner. If it has been cut through,
decrease pressure.
4.
Continue increasing or decreasing pressure until the label no longer tears when
removed or the liner is not cut through.
Note about Magnetic Media.
The recommended starting knife pressure for the magnetic media is 22. This
media is not meant to be cut all the way through because there is no liner. Instead, this knife pressure
setting is meant to score the magnetic media so that it can be removed by hand after printing. In some
cases, it may be necessary to tear the outer excess material from the intended shape.
If you do cut all the way through this media, it can damage the wear strip, break the knife tip or cause media
jams.
