Introduction
3M Label Sheeting, Validation Security Sheeting
with Ensure™ Image and 3M™ Overlaminate Film
are designed for the production of reflective labels
and validation stickers. The sheetings are printable
with hot stamp label making equipment using
commercially available hot stamp foils which
are then protected with a clear, weather resistant
overlaminate film. The sheetings and films have
pressure sensitive adhesives protected by removable
liners.
™
Printing
Reflective sheetings can be printed with
commercially available hot stamp foils and printers.
The hot stamp foils are opaque and printed copy of
reflective sheeting will appear black when viewed
by reflected light. To obtain maximum reflectivity
of finished stickers and visibility of security
markings, it is recommended that sticker copy be
direct printed only.
When using Validation Security Sheeting with
Ensure™ Image, the label printer should provide
the correct orientation of the printed design with
the security image. Consecutive numbering
must read across the web. Contact a 3M
technical representative for assistance on mark
orientation, roll unwind direction and liner scoring
requirements.
Both face and liner side printing are possible with
certain hot stamp label maker processes using
reflective sheetings. Contact your equipment
supplier to determine accessories and adjustments
needed to attain optimum printing. Print head
temperature must be maintained according to foil
and equipment supplier recommendations. Some
units require precaution to minimize contact of the
sheeting and overlaminate stocks with the heated
surfaces to prevent web breaks.
Processing
3M™ Overlaminate Film Y-7735FL is applied in
continuous fashion after all design and number
printing resulting in a smooth, clear laminate.
Thread-up leaders may be necessary in some
units and subsequent rolls should be spliced to
the preceding roll for operational convenience.
Allowances must be made for roll thread-up and
splices when considering quantities. A waste
factor of 1.2 to 2.5% has been reported by some
users when operating at normal conditions. For
new programs a 3% waste factor is suggested for
estimating material requirements.
In-process die cutting for the overlaminate/sheeting
construction is possible, but users are cautioned to
maintain cutting dies in sharp condition. Experience
to date shows that butt cut processing provides
maximum cutter life as compared to steel rule die
cut method.
Roll lengths supplied by 3M are 250 yards
maximum. Widths of sheeting will depend on the
design and machne capability. Some machines
require overlaminate stock width to be 1/8 inch
narrower than base stock to allow for proper stock
alignment on finished stickers.
Equipment and foils evaluated to date include
Markerm Corporation Hot Stamp Label Maker LP
375 TS and Markem Corp. Series 730 matte hot
stamp foils. With this unit and Series 730 foils,
the print heads must be kept as close to 250°F as
possible when printing on reflective sheetings.
Another unit used successfully is the Model 164
Franklin Precision Hot Stamping Machine, Franklin
Manufacturing Corp., Norwood, MA. Users are
cautioned to assure themselves that processing
and finished stickers will meet their expected
requirements.
