Thermal films materials
Clutch pressure may have to be adjusted to obtain
a quality output. Some thermal films require cooling to
assist with the control of the expansion and contraction of
the laminate or image.

is to not crush the substrate. Most substrates only require
about 20-50 psi of pressure, but variables can effect how
