Text and/or graphics printed on paper with an
adhesive backing and then cut to a specified shape and size.
Similar to a decal; decals are printed on an adhesive backed
film,
where as labels are printed on adhesive backed paper. Label is
commonly used as a generic term for
Decals,
Nameplates,
Overlays,
Legend Plates, and
Tags, as well as
labels.

Lamicoid
(also lamacoid)
A
brand name of engravable phenolic sheet stock no
longer being produced. The trademark was originally owned by
Mica Insulator Corp. and later by 3M, Allied-Signal, Inc. and
Norplex. Lamicoid (Lamacoid) has become a generic term commonly used for
specifying 2- or 3-ply, laminated
engraving stocks and/or the
nameplates,
tags, or
legend plates produced
from the stock.

Phenolic Sheet on our Materials Reference Chart.
Laminate
(1.) A process by which different materials are
layered and then bonded together using
adhesives, pressure,
and/or heat.
See High Pressure
Laminate on our Materials Reference Chart.
(2.) A film,
adhesive, or
substrate
that is to be layered and then bonded to another film, adhesive, or
substrate. Common laminates are pressure sensitive adhesive backings
and clear films used to protect printed images from abrasion,
chemicals, and/or fading.
See Laminates on our Materials Reference Chart.
Leading
Pronounced "led-ing", as in "lead
pencil". Leading is the vertical space between lines of text.
Like letter and word spacing, the right amount of leading makes text
easier to read. Often expressed as a percentage of the vertical
height of characters, it separates two baselines in text. For
example, leading between two lines of 1" high characters, where
baselines are 1.25" apart, is 125%. This means you have a 25% space
between your lines.
Legend Plate
(1.) Legend Plate is most commonly used to refer to
a push-button flag or a
tag with a hole in it that
fits around a push-button, pilot light, or selector-switch. Legend
plates are typically rectangular, and/or round with one large hole
near the center. The hole may or may not have a male (tab) or female
keyway used to key or hold the legend plate in a specific
orientation relative to the device it is labeling.
(2.) A generic
term used for
engraved
nameplates or tags used to
label the function of devices on and in electrical control panels.
The engraved tags have the explanation (or legend) of what
each device is, does, and/or how to use it.

Legibility
The quality of a
nameplate,
label, decal,
or sign's
typefaces that allows it to be easily read
and deciphered.
See Readability.

Liner
Also known as backing. A layer of paper or
film
that protects the pressure sensitive
adhesive backing of an
item until it is ready to be applied (or stuck). A silicone coating
on the liner provides the typical easy removal of the liner.
Logo
An often-stylized group of letters, words, symbols,
and/or graphics used to represent a business and/or its products.

Low Surface Energy (LSE)
Specifically low surface energy (LSE)
plastics
and a pressure sensitive adhesive’s (PSA’s) ability to bond to
them. Surface energy defines the ability of a PSA to "wet
out" plastic surfaces to allow adhesion. Surface wet out refers
to how well a liquid or PSA flows and intimately covers a surface.
Maximum adhesion develops when the PSA thoroughly wets out the
surface to be bonded. The greater the wet out, the better the
surface coverage and the greater the attractive forces between
adhesives and plastic surfaces. Surfaces with high surface energy
bond more readily because they are easier to wet with conventional
adhesives than are low-energy surfaces.
Generally if water "beads up" into
droplets on a plastic, it has a low surface energy, and adhesives
will not thoroughly wet out or bond well to it. Low surface energy
plastics include polypropylene, TPOs, and polyethylene.
Historically, flashing was used to raise the surface energy
of LSE plastics. More recently, some new PSAs have been developed to
work specifically with a wide variety of LSE plastics. See flashing.
Water does not bead and will wet out High surface
energy plastics such as ABS and
polycarbonate. Similarly,
conventional PSAs (which possess a LSE) bond well to these
materials.

Trade name for Acrylic Sheet. Similar to
Plexiglas.

M
The Roman numeral for 1000, "M" is often
used as a unit of measure abbreviation for "1000",
"1000 pieces", or "Per 1000 pieces".

Manufacturer’s Nameplate
Also known as a data plate. A manufacturer’s
nameplate
typically contains the manufacturer’s name, logo and
contact information, country of origin or manufacture, date of
manufacture, serial number, voltage, full load amps, cycles, horse
power, maximum pressure, associated drawing numbers, and/or other
associated technical information that the end user of the product
must know. The information found on manufacturer’s nameplates is
commonly regulated in the form of a code or specification written
for the specific product type, and the anticipated type of product
user, by a governing body, industry association, council, etc.

Masking
A protective paper or film used to protect an
item during final fabrication, inspection, and shipping. The masking
is typically removed by the customer just prior to installation or application.
Matte Finish
Having a dull surface; not shiny. A matte surface
has a low level of reflectivity.

Membrane Switch
In its most basic form, a membrane switch is
composed of three layers: (1) A shorting pad (a film (or
membrane) containing a contact (or conductor) in specific areas).
(2) A spacer layer with holes that are aligned with the shorting pad
contacts. (3) A printed circuit board (PCB). These three layers are laminated
together to form small, low profile switches (or buttons) covered
with a film to provide a smooth and/or slightly bubbled feel.
The definition of membrane switch is usually expanded to include a
graphic overlay laminated to the top of the three-ply switch.
Common examples of membrane switches can be found on many microwave
ovens and dishwashers.
Memory
The property of a material that causes it to shrink
or return to its original dimensions after being formed, stretched,
or subjected to temperature changes.

Mil
A unit of measure for expressing the thickness of a
film.
One (1) Mil is equal to .001" or (1/1000"). The thickness
of vinyl film when expressed in Mils typically includes the
thickness of its adhesive.
Mill Finish
(1.) The surface finish of
sheet metal upon
exiting the production line rollers, slitters, etc. that produced
it. Mill finish sheet metal may have minor surface imperfections or
scratches. (2.) A characteristic of the ground (or milled)
finish used on the rolls that produce sheet metal. This finish is
transferred to the sheet metal under the pressure of the rollers.
