TACK
The property of a pressure sensitive label which
causes it to adhere to a surface instantly with minimum pressure
and contact time (measured by TLMI Tester or equivalent equipment).
TAMPER-RESISTANT LABEL
A pressure sensitive construction made with a weak
face material so that (attempted) removal of the label usually results
in its destruction.
TEAR-STRENGTH/TEARING STRENGTH
The force required to tear a label specimen under
standardized conditions. Determined by using an instrument designed
to simulate the tearing encountered under general use conditions.
TENSILE STRENGTH
The force parallel to the plane of an applied label
required to break a given width and length of paper under specified
conditions.
TENSION
The mechanical control of unwinding or rewinding
paper, film, foil and other roll materials. The stress caused by
a force operating to extend, stretch or pull apart.
THERMAL TRANSFER PRINTING
An imprinting method that uses heat and pressure
to melt a wax or resin based ink onto a label.
THICKNESS
The thickness of a sheet of paper or plastic measured
in units of one thousandth of an inch; the measuring units are called
mils or points.
TIPPED-ON LABELS
A method of label application in which the carrier
is peeled back and labels fall or "tip" onto the substrate.
TLMI/TAG AND LABEL MANUFACTURERS'
INSTITUTE
A trade organization in the pressure sensitive label industry.
TOOLING
Usually refers to die cutters, butt cutters, etc.,
used to cut out the labels.
TOOTH COUNT
Refers to the actual number of teeth on the gear
attached to the dies and printing cylinders. Each tooth count refers
to a separate and actual repeat length.
TOP COAT/TOP COATING
A substance coated onto a label material that will
enhance printing or the appearance of the finished label. For example,
some films are top coated to ensure better ink anchorage to the
surface of the material.
TPI/TIES PER INCH
In perforations, the number of material ties that
exist between each hole.
TRACTOR FEED
Round or rectangular holes punched into the edge
of a liner to maintain the register of computer imprintable pressure
sensitive labels during imprinting. Holes can be cleanly cut or
in a starburst.
TRANSPARENCY
That property of a material which transmits light
rays so that objects can be clearly seen through the material.
TRANSPARENT LABEL
A pressure sensitive label inwhich the face material,
adhesive, and protective coatings transmit light so that objects
can be seen through it.
TRAPPING
Overlapping colors to allow for slight misregistration
on press without losing color integrity.
TURNING BARS
Stationary bars on a press which guide the web in
a manner that it is turned front to back, and will be printed on
the reverse side by the printing units.
