DEBOSS
Condition in which an image is depressed below the normal surface
of a material. Embossing has the opposite effect, creating a raised
image.
DESTRUCTIBLE LABEL
A pressure sensitive construction made with a weak face material
so that (attempted) removal of the label usually results in its
destruction.
DIAMETER
The length from one side to the other of a circle or sphere.
DIE
The tool or device used for imparting or cutting a desired shape,
form, or finish from a given material.
DIE BLADES
Sharpened, thin steel blades used in flat or rotary dies. Also refers
to blades on machine engraved or EDM manufactured rotary dies.
DIE CUT
The actual shape of a pressure sensitive label made by the cutting
edge of a die.
DIE LIFE
Mileage (number of impressions) expected from a new die and expected
following a resharpening of a die.
DIE LINES
A hand drawn or computer generated layout of the die cut shape or
shapes on a clear or matte finish acetate or mylar.
DIRECT THERMAL PRINTING
A specialized printing technology that uses rapidly-heated pins
that selectively activate a heat-sensitive coating inherent in the
face material, thus forming the desired copy or images.
DISPENSER
A device that feeds pressure sensitive labels, either manually or
automatically, in pre-determined units. Dispensers in box form can
serve as containers for a roll of labels.
DISTORTED
Intentionally shrinking artwork a particular way
to compensate for stretching of plates on press.
DOCTOR BLADE
A thin flexible blade used to scrape off excess ink on an anilox
roll.
DOT
Many individual dots make up a halftone.
DOT MATRIX PRINTING
An economic and versatile method of printing that produces images
by printing tiny ink dots closely together. First, a computer sends
data which determines the arrangement of pins that are to be fired
against a ribbon. These pins are in horizontal and vertical rows
on the printing head. As the printing head moves back and forth
across the page, the pins fire (many times per second), forming
an image.
D.P.I.
Dots per inch; a measure referring to dot resolution in images created
by dot matrix, laser, and thermal printers and imprinters.
DRAWDOWN
A swatch of color or coating used for testing. It's done by
spreading a couple of droplets of ink or varnish across a sheet
of stock.
DRY PEEL
A type of label construction in which two materials are bonded together
with a dry adhesive. The top ply of the construction can be removed
with no adhesive residue. The bottom ply is typically made of clear
material, so the substrate can be seen through it. Commonly used
to produce instantly redeemable coupons or for promotions.
