The degree to which a label surface — including printing and protective coatings — is able to resist being rubbed or worn away by friction.

Pressure?sensitive or heat activated coating used to bond a label to the application surface.

An image containing a pattern of vertical bars and spaces, which represent characters of data that are readable with barcode scanners.

Tests the quality and readability of printed barcodes.

The amount of force required to separate joined surfaces.

The resistance of a material to the deteriorating effects of exposure to various chemicals under specified conditions.

The internal strength of an adhesive and its ability to resist splitting caused by external forces. It is measured by its resistance to forces parallel to the surface. Good cohesion is necessary for clean removal.

Fan-folded labels manufactured form a continuous web of label stock which is not cut into units prior to execution. Continuous labels are mostly used for data processing applications.

The process of using dies or sharp steel rules to cut any shape for labels.

A specialized printing technology using rapidly heated pins that selectively activate a heat sensitive coating applied to the face stock thus forming the desired image.

Impressing an image in relief to achieve a raised surface, either by overprinting or on blank paper in a process called “blind embossing.”

Acetate, polyester, polyethylene vinyl and other polymeric. Face material manufacturing from synthetic high molecular weight polymers.

The surface property of a paper or film determined by its texture and gloss. A gloss finish, for example, can be shiny and highly reflective, while a matter finish is generally dull and reflects little light.

The process of reproducing full printed images. The image must be converted to sea set of halftone screened negatives which are a series of dots of various sizes. A halftone negative is made for each of the separate color components of the images (cyan, magenta, and yellow, black). These color separations are made into printing plates, one for each color and when printed, the overlapping dots of the color components reproduce a full color image.

This is the property of a material which inhibits the occurrence of physical or chemical changes caused by exposure to high temperatures.

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

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

A non-impact electro-photographic 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.

Series of small cuts made in labels and/or their release liner to facilitate tearing along a predetermined line.

One of many high-polymeric substances, including both natural and synthetic products, but excluding the rubbers. Plastic is capable of flowing and pressure or tensile stress, if necessary, into the desired final shape.

A strong film having good resistance to moisture, solvents, oils and many other chemicals. It is usually transparent.

A pressure-sensitive adhesive characterized by low ultimate adhesion to a wide variety of surfaces that can be removed without damage to either the label or the substrate.

Adhesive left on a substrate when a label is removed.

A machine which takes rolls from the winder, slits or rewinds into smaller rolls.

Radio frequency identification (RFID) is a wireless technology for communication between electronic devices. In the barcode industry, RFID tags are used in proximity label scanning, while in the card industry, it is RFID technology that enables a contactless smart card to communicate with a card reader.

Pressure-sensitive labels that are produced in a continuous roll form.

To make an impression or a partial cut in a material for the purpose of bending, creasing, folding or tearing.

Method of printing in which the ink is forced through a design on a tout screen and onto the object to be printed. This process results in a heavy ink deposit that provides excellent outdoor durability.

This is typically a clear film with adhesive on one side, and no liner. This is a lower cost alternative to liner over laminations. Sometime there is a release coating on the top side of the film to allow for smooth and easy unwinding.

Internal or cohesive strength of the adhesive.
