FACE CUT LABEL
A die cut or square cut label from which the matrix,
or waste between labels, has not been removed.
FACE MATERIAL/FACE STOCK
Any paper, film, fabric, foil or plastic material
suitable for converting into pressure sensitive labels. In a finished
construction, the face material is bonded to an adhesive layer and
carried on a liner. It is the functional part of the construction.
FACE SLIT
A slit in the face material of a pressure sensitive
product to facilitate removal from the backing.
FACE SPLIT
A linear cut in face material during coating or
converting to meet special application requirements.
FADE/FADING
A gradual decrease in brilliance of color; often
applies to the change in color produced by prolonged exposure to
light.
FAN-FOLD/FAN-FOLDED LABELS
Pressure sensitive labels on a continuous backing
that are perforated, then folded back and forth along the perforations
to create a flat pack.
FEATHERING
A defect in printing which is characterized by ragged,
uneven, or coarse edges.
FEED SLOTS
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.
FILM
Plastic face material manufactured from synthetic
high molecular weight polymers. Examples are polyester, polyethylene,
and vinyl.
FINISH
The surface property of a paper sheet determined
by its surface contour and gloss. Terms referring to paper finish
include: antique, eggshell, vellum, machine, English, super-calendered,
and plate.
FISH EYES
Round or eye-shaped deformations in a coating.
FIXER
Chemical used to stop film from developing.
FLAG
A marker, usually made of strips of colored paper,
placed in rolls of pressure sensitive materials during printing
(converting) to designate a deviation from a standard-such as a
splice, defect, or specification change. It can also mark a specific
length.
FLEXIBILITY
A property of face material, measured under specified
conditions, that indicates how readily it will conform to curved
surfaces.
FLEXOGRAPHY
A rotary web letterpress method of printing characterized
by raised-image, flexible rubber plates and fast-drying inks.
FLUORESCENT PAPER
A paper coated with a pigment which reflects light
in such a way that it has a glowing appearance or effect.
FOIL
A thin metal sheet used as a face material.
FOIL PAPER LAMINATE
A face material consisting of metal foil laminated
to paper. The foil usually carries a clear coat to improve ink receptivity.
FOOD CONTACT ADHESIVES
Adhesives meeting specified sections of the Food
and Drug Administration Code of Federal Regulations. These regulations
cover direct food labeling, as well as incidental contact. Special
product recommendations are necessary for specific applications.
FONT
All characters of a particular type.
FOUR COLOR PROCESS PRINTING
Printing and reproduction of full color images using
the four process printing colors—yellow, cyan, magenta, and
black—to create an image with an indefinite number of colors.
FROZEN EDGE
The inability to separate a pressure sensitive label
from its liner along one edge. This is generally caused by an absence
of silicone on that edge.
