Data matrix code

By using a two-dimensional data matrix code (2D code), the information density per area can be increased significantly compared to one-dimensional barcodes (1D code). In a data matrix code, the information is coded very compactly in a square or rectangular areas as a grid of dots. When a data matrix code is read, two different bar widths are no longer defined clearly in their order, as in a one-dimensional barcode, but rather the arrangement of the equal-sized dots within the frame and in the matrix grid.

Data sharing

Data sharing allows access to shared information which can be saved centrally.

Data warehouse

A data warehouse is an extensive, user-orientated central database which supports management in information procurement, analysis and planning.


Detachment of a material in layers in a direction parallel to the surface

Dimensional stability

Behaviour of a material in relation to the consistency of its dimensions in length and width under influences such as temperature, moisture, solvents etc.


Labels for electronic anti-theft applications are destroyed with a deactivator before leaving the shop. To do this, the labels have an oscillating circuit consisting of a coil and a capacitor. The capacitor is equipped with special planned short circuit points, called dimples. The deactivator uses a strong magnetic field to destroy the capacitor at the dimples and thus upset the oscillating circuit. The EAS label is then no longer recognised by the detectors.

Direction of movement

Common information given for papers, referring to the alignment of the paper fibres parallel to the direction of movement of the paper machine. It is especially significant for printing and processing in label manufacture.

Direct thermal printing

In direct thermal printing, the thermal pulses from the thermal head are transmitted to thermo-reactive paper. There they trigger a chemical colour reaction in the special thermal layer of the adhesive bond.

Discrete code

Barcode in which each character begins and ends with a bar. The separator space is not part of the barcode.


Device for automatic or manual labelling


Substance system in which a substance is distributed extremely finely throughout a dispersion medium. In practice, watery dispersions are often used in the form of lacquers, adhesives or inks.

Display palettes

Palettes which are used both for transport and for presenting the goods for sale in retail.

Disposal bars

Label material which surrounds the actual self-adhesive label

Dot matrix (needle) printing

Dot matrix (impact) printers are generally called needle printers. The print is applied to the substrate using small needles. The printing ink contained in the ink ribbons is 'impressed' mechanically, achieving especially good anchoring on the label surface.

Drawing sheet

Flexible die for use on magnetic cylinders, magnetic foundations or other special equipment.


Name for a sandwich bond
