B

BACK PRINTING
Refers to printing on the underside of a pressure sensitive substrate or laminate, i.e. on the adhesive or back of liner.

BACK SPLIT
The slit in the release liner that facilitates its removal by hand.

BACKGROUND
The area surrounding a printed symbol.

BACKING
The carrier sheet of material, as opposed to the face material, in a pressure sensitive lamination. It always has a release coating applied so that the adhesive will not stick permanently to the backing. Also known as the release liner.

BALL-UP
Specific term to describe the tendency of an adhesive to stick to itself; cohesiveness. Such an adhesive, when rolled between fingers, will not spread smoothly but will roll up in small spheres.

BAR CODE
In optical reading, a system of symbols which identifies data through length, position size or thickness of lines or symbols. Codes are normally machine printed.

BAR CODE DENSITY
The number of data characters which can be represented in a linear unit of measure. Bar code density is often expressed in characters per inch.

BAR CODE READER
A device used to identify and read bar code symbols.

BAR CODE VALIDATION
The process of checking that the correct number has been printed as expected. The validation process is not a check of print quality of the bar code; it will not tell you if the code is readable by other bar code readers. This term should not be confused with Bar Code Verification.

BAR CODE VERIFICATION
A bar code only becomes effective if it can be read or scanned the first time and every time. To ensure that bar codes will scan first time and meet the acceptance requirements. Coast Label uses a quality control device called a verifier to insure that the bar code matches the ANSI grading standards within the permitted tolerance levels, as well as the human readable information is present as specified.

BAR LENGTH
A measure of the length of the vertical bar in a bar code.

BAR
The dark element of a printed bar code symbol.

BAR WIDTH REDUCTION
Reduction of the nominal bar width dimension on film masters or printing plates to compensate for printing gain.

BAR WIDTH
The thickness of a bar measured from the edge closest to the symbol start character to the trailing edge of the same bar.

BARRIER COAT
A coating applied to the face material on the side opposite to the printing surface to provide increased opacity to the face material and/or to prevent migration between adhesive and the face material and improve anchorage of adhesive to face material. Sealer coat.

BASIC SHEET SIZE
The size of a sheet of paper which is used to determine paper weight. Sizes vary depending on the type of stock.

BASIS WEIGHT
The weight in pounds of a ream of paper cut to a given size. Most backing papers used in pressure sensitive laminations are based on a ream size of 500 sheets 24″ x 36″. Face papers are more typically 500 sheets 25″ x 38″.

BEARER
Type-high supports designed into each end of a printing plate to help carry part of the impression load and to help prevent bounce. Also the load bearing surfaces(s) of a rotary die, usually positioned at each end of the die.

BIAX
Biaxially oriented material, that is, oriented in the machine and transverse directions.

BI-DIRECTIONAL READ
The ability to read data successfully whether the scanning of the bar code is done left to right or right to left.

BI-DIRECTIONAL SYMBOL
A bar code symbol which permits reading in complementary directions.

BINDER

The component of an ink that supplies the cohesiveness.

BIT
An abbreviation for ‘binary digit’. A single character in a binary number.

BLACK LIGHT
Black light inks are invisible to the eye in a normally lit environment, but can be seen when exposed to a black light, which emits long wave UV radiation. Therefore the inks must be checked during the manufacturing process by the use of black light / UV light.

BLACK LIGHT VARNISH

A clear varnish applied on top of the label that glows brightly when exposed to black UV light, while giving the appearance of a normal clear varnish under most lighting conditions. This is a security feature offered by Coast Label.

BLACK-AND-WHITE

Originals or reproductions in single color or monochrome, usually refers to artwork.

BLEED
When the printed image extends beyond the trim edge of the label.

BLEEDING
The diffusion or migration of an ink component or dye into an area where it is not wanted. The spreading or running of a pigment color by action of a solvent. Also the diffusion of migration of an adhesive component into the face material.

BLEED-THROUGH
See penetration-migration.

BLIND EMBOSSING
A design which is achieved by passing the label material through a matched pair of male/female embossing cylinders to give a bas-relief (raised) effect.

BLOCKING TEST
A test used in measuring the tendency of surface-to-surface sticking.

BLOCKING
Undesired adhesion between the plies in rolls of pressure sensitive stock usually due to adhesive ooze, improper drying of inks, or improper curing of coatings, often to the extent that damage to at least one surface is visible upon their separation if they can in fact be separated.

BODY STOCK
See face material.

BOLD-FACE TYPE
Name given to type that is heavier than text type with which it is used.

BOND
To attach materials together by adhesives.

BONDING RANGE
The time during which satisfactory bonds can be made. A bonding range of from 10 to 30 minutes indicates that maximum bonds can be achieved between 10 and 30 minutes.

BONDING STRENGTH
In paper, the force with which the fibers adhere to each other. In surface coatings, such as inks and adhesives, the strength with which the dried coating adheres to the surface of the substrate. Also refers to the degree of adhesion of a pressure sensitive face material to any surface.

BRIGHTNESS
The reflectivity of a sheet of paper for blue light measured under standardized conditions on a particular instrument designed and calibrated specifically for the purpose. Strictly speaking, brightness is not a colormetric quantity.

BURN
Common term used for printing plate exposure.

BURSTING PERF
A fold perforation that permits mechanical bursting.

BURSTING STRENGTH
The pressure required to rupture a material specimen when it is tested in a specified instrument under specified conditions. It is largely determined by the tensile strength and extensibility of the material.

BUTT CUT LABELS
Rectangular labels in continuous form separated by a single precision-depth knife cut across the web that goes through the face stock and adhesive, but not through the liner. Also called face cut or knife cut.

BUTT SPLICE
An end to end joining of two similar materials used for continuity of surface and design. It is often used in joining stickyback, printing plates and webs of substrates in process.
