| Diffractive optically variable devices |
the collective term for images that display complex visual effects that change according to the viewing angle, based on the phenomenon of diffraction. These effects are varied, and are typically three dimensional (exhibiting depth as well as width and height), kinetic, multi channel (in which one image, or part of an image, changes into another) or animation. DOVIDs are created either via the interference of two laser beams (ie holograms) or through direct write processes using an electron or laser beam. |
| Digifeiting |
the reproduction (as in counterfeiting) of documents and packaging using digital reprographic technology. |
| Digital printing |
the reproduction of digital images and data on physical surfaces via inkjet, laser or dot matrix printers. The images are transferred directly to the printer and the process is particularly suited for documents, labels etc with variable data. |
| Digital stamps |
tax stamps containing a unique digital encrypted code that is stored in a database and can be used for remote verification |
| Digital watermark |
digital data embedded directly within print content which is imperceptible to humans but readable by computers. |
| Diversion |
genuine goods distributed outside of and often in violation of authorized distribution channels (also known as parallel trading) |
| E-pedigree |
an electronic statement of a product’s history and passage through the supply chain, with each movement and trade recorded so that, at any point in the chain and at its end, the lineage of the product can be obtained |
| Embossing |
the transfer of a raised pattern from a hard plate to a softer material. This mechanical transfer is usually facilitated by means of heat and always with pressure. |
| Encoding |
the recording of information onto a receptive medium |
| Encryption |
the adaptation of information using ciphers so that unauthorised access is restricted. |
| Fiscal Verification the means whereby go |
|
| Flexo printing (flexography) |
the method of printing whereby a mirrored 3D relief of the required image is made in a rubber or polymer material. A measured amount of ink is deposited upon the surface of the printing plate, the print surface then rotates, making contacting with the print material (substrate) and transferring the ink. |
| Fluorescence |
see Luminescence |
| Foil |
a material comprising a polyester carrier with one or more coatings, a release layer and an adhesive layer. The foil is transferred – generally by heat – onto paper, labelstock, textiles etc and the carrier is stripped away, leaving the coating which is bonded to the substrate by the adhesive. This coating can be colour shift, irridesence, metallised, holographic etc. Also know as a hot stamping foil or a transfer foil. |
| Forensic markers |
