Glossary of Terms Related To Label Printing

As a premier label printing company, there is a variety of technical terms and industry jargon we may use when strategizing on the optimal way to meet our clients’ label printing goals.

We are pleased to partner with Avery Dennison and share this valuable glossary with our customers. Here you will find definitions of frequently-used terms, as well as other resources related to label printing.

I-L Terms


Impact Printing: Any printing system where a micro processor controlled drives a ribbon into contact with the print surface (dot matrix) or the print surface into contact with the ribbon drum printer).

Impregnated Paper: A general term for soft porous papers which are to be or impregnated with solutions or compounds of various types. Wet tensile strength and degree or rate of are important qualities.

Impression Cylinder: In printing, the cylinder on a printing press against which paper picks up the impression from the inked plate in direct printing, or the blanket in offset printing.

Infra-Red: Part of the electro-magnetic spectrum between the visible range and the radar range. Radiant heat is in this range, and infra-red heaters are much used in sheet thermoforming.

Inhibitor: A substance which slows down chemical reaction. Inhibitors are sometimes used in certain adhesives to prolong its life or storage.

Initial Tack: Adhesives usually have two adhesive stages: 1) Initial tack at which time it is sticky enough to hold parts together; (2) Set at which point the adhesives has firmly bonded them.

Injection Blow Molding: A molding procedure whereby a heat softened plastic is forced from a cylinder into a relatively cool cavity which gives the article the desired shape.

Ink Fountain: In printing presses, the device which stores and supplies ink the inking rollers.

Ink Jet: A method of printing using liquid ink projected a drop at a time against a substrate.

Instron: Test instrument used to determine tensile and adhesion values.

IR: Infrared Scannable


No Terms


Kiss-Cut: Kiss-cutting refers to a die cutting method where the die cuts through the laminated material and adhesive and stops before rupturing the liner. In this process the waste matrix is often removed.

Knife Coating: A method of adhesive coating. It essentially consists of a rigid adjustable blade mounted above a roll. The adhesive is pumped behind the blade so it is pulled under the blade.

Kraft: A sulphate wood pulp paper.


Label: The functional portion of a pressure-sensitive construction comprising the face sheet and adhesive, die cut into various shapes.

Lacquer: A solution or suspension of one or more materials in volatile solvents capable of forming a protective and or decorative film or a film with special surface properties, after the solvents have evaporated.

Laminate: A web material formed by bonding two or more materials together.

Lap Splice: A splice made by overlapping the ends.

Laser: The acronym for light amplification by stimulated emission radiation. The laser is an intense light beam with very narrow band width that can produce images by electronic. It makes possible imaging by remote control from computers or facsimile transmission.

Laser Printing: A non-impact electrophotographic process utilizing a laser beam to scan the surface of the drum creating a latent image which attracts toner. The toner is then transfer fused into the print surface.

Latex: An emulsion of rubber or resin particles dispersed in an aqueous medium a natural synthetic elastomeric dispersion in a aqueous system.

Latex Paper: Impregnated Paper / Saturated Paper. Paper manufactured by two major processes: 1) the latex is incorporated with the fibers in the beater to formation of the sheet; 2) a performed web of absorbent fiber is saturated with properly latex. The papers are characterized by strength, folding endurance, resistance to penetration by water, flexibility durability and resistance to abrasion.

Lay Flat: An adhesive material with good non-curling and non-characteristics.

LCJ: Laser Copy™ Jet

LD: Low Durabilty

Legging: Legging can be exhibited when unwinding a roll, or in the end-use application. When peeling back adhesive backed products, one can witness the adhesive bonding to both the end use, and laminated materials. When this occurs, the adhesive strings between both materials upon removal. In an end-use application, legging can be the result of Plasticizer migration. In a roll of tape, legging can be the result of an inadequate release system.

Letterpress Printing: Printing process in which ink is applied to a surface from portions of rigid printing plates or type.

Lifting: Refers to the condition when a tape, on its own accord comes away from the surface to which it was applied.

Liner Side: In roll form it is referred to that side of the roll protected by the release liner.

Luster: Gloss of a finish.
