- Sandwich bond
Three-layer self-adhesive construction in which, once the top two layers are adhered, the top label can be removed and re-adhered
In RFID: an electronic device which can send and receive radio waves. If it is combined with a digital signal processor which converts the waves into information bits, the scanner is called a reader. In barcodes: general name for a device which has an integrated laser scanner. These devices can be stationary or mobile. Scanners convert optical information into electrical signals and transmit these to a computer for subsequent decoding. The antenna, transmitter (or exciter) and receiver are integral parts of the scanner.
- Screen printing
Printing process in which the ink is pressed onto the material to be printed through a fine-meshed fabric.
- Second reading rate
Number of correct readings in two or more reading attempts, divided by the number of reading attempts.
- Security label
Label which cannot be counterfeited. Term for a wide range of different labels which have special properties intended to protect against theft or make products more difficult to counterfeit.
Consignment data exchange system (Sendungsdaten-Austausch System)
- Self-checking barcode
A barcode which allows each character to be checked in accordance with a prescribed algorithm. Self-checking barcodes are inherently safe. This means that a change to a character is recognised as an error and prevents reading. Two simultaneous contradictory modifications within a character and scan line may lead to incorrect reading due to substitution. The substitution error can be recognised using a check digit.
A device which reacts to a physical stimulus and produces an electronic signal. See also 'Scanner'.
- Separating layer
Coating applied to the substrate to allow simple separation between adhesive masses.
- Separating space
The space between the last bar of a character and the first bar of the next character in a discrete barcode.
- Shear strength
Resistance of an adhesive to static loads (weight) at the level of the label material.
- Silicone paper
Material coated with silicone. It ensures that both the labels and the matrix can be removed easily.
A stockkeeping unit is an identification number in warehouse management. Each product in the warehouse is give an SKU by the dealer. This SKU is then used to order a product from the warehouse, define the location and manage the stock. Each product and each product variant has its own SKU, such as for different colours or models.
- Smart label
A smart label is a combination of a barcode label and a passive RFID tag.
- Smart shelves
Smart shelves are intelligent shelves equipped with RFID reading devices. They can automatically record goods which have been placed incorrectly. Vacancies or out-of-stock situations can also be prevented, since the number of items available on the shelf is recognised. If required, the system can automatically inform a member of staff that the specific item needs to be restocked on the shelf.
- Smear resistance
Resistance of a freshly printed ink on paper or film surfaces against smearing or smudging.
Substance which is added to some plastics, mainly PVC, to make then more flexible, malleable and ductile.
- Solvent resistance
Resistance of a material, e.g. a self-adhesive label, against the solvent effect of certain organic solutions.
The light element between two bars in a barcode
- Start/stop character
Every barcode starts with a start character and ends with a stop character. This generally allows readability in two directions and recognition of the barcode type.
