Exceptions to the above are:
The warranty applies to films that are exposed at a
vertical angle (defined as 90°+/-10°). A significant
decrease in durability may be experienced if films
are exposed other than vertical. Thus horizontal
exposure is not recommended

Minimum Cutting Heights
The minimum height recommended for text is
10mm for both mirror gold and silver. This is based
upon cutting and weeding evaluations using
uppercase Helvetica Medium copy. Users are
encouraged to do their own evaluation for specific
heights and design detail required for a particular
job. The variable characteristics of electronically
controlled cutting equipment requires users to
verify their specific requirements.
General Prespacing
SCPS-100
Factors that affect cutting quality and capability that
the user needs to take into consideration are:
a. Sharpness of knife blade (dull blades impart a
serrated look to the edge of the cut film).
b. Weight on knife blade.
a) Ideal weight will result in a slight scoring of
the liner.
b) Too light a weight will cause incomplete
cutting through film and adhesive.
c) Excessive weight results in cut liner, the
blade dragging (which will accelerate wear)
and cause a serrated edge on the film.
Weeding
It is recommended that 3M™ Scotchcal™
ElectroCut™ Film Series 7755SE have the excess
film weeded (removed) as soon after cutting as
practical. This is to minimise the effect of possible
adhesive flow, 24 or more hours after cutting.
Kiss Cutting
a. Cold Kiss Cutting
Steel rule dies have to be used for kiss cutting
Scotchcal ElectroCut Film Series 7755SE. It is
recommended that a sheet made out of steel be
used as a support during kiss cutting.
Note: The stripping rubbers mounted close to
the die must not exceed the height of the knife
by more than 0.5mm.
