law://eu/dec/2018/576@2026-11-13THE EUROPEAN COMMISSION,Having regard to Directive 2014/40/EU of the European Parliament and of the Council of 3 April 2014 on the approximation of the laws, regulations and administrative provisions of the Member States concerning the manufacture, presentation and sale of tobacco and related products and repealing Directive 2001/37/ECnote, and in particular Article 16(2) thereof,Whereas:
HAS ADOPTED THIS DECISION:
| Overt | Semi-covert | Covert |
|---|---|---|
| GuillocheOrnamental pattern of two or more interlaced bands that are printed in multiple non-standard colours. | Laser imagesImage becomes visible to the human eye only when emblazed with a light of a specific wavelength, such as a laser pointer. | DNA taggantsForensic marker which uses combinatorical mathematical principles to define nucleotide sequences. |
| Rainbow printingCombination of two or more colours and subtly merging of colours into each other, which leads to the formation of intervening tints (taking on rainbow colours). | Polarised imageImage becomes visible to the human eye only when a specific polarising filter is placed over it. | Molecular taggantsChemical marker which, often formulated in the base materials of the object tagged to, allows for the detection of dilution and mix ratios in materials. Uniquely encoded and incorporated at trace levels. |
| Latent imageA line pattern printed by intaglio that reveals a different image when tilting the object on which it is printed. May be combined with colour-changing ink. | UV dull paperSpecial paper that will not reflect ultraviolet light. Suitable for printing with ultraviolet (UV) inks that will show up under special UV lamps. | Security fibres (covert)Invisible fluorescent fibres that are randomly placed on suitable paper. Cannot be scanned or photocopied and will only become visible under special UV lamps. |
| Colour-changing inkReveals changing colours when viewed under different angles. | Security fibres (semi-covert)Visible fluorescent fibres fully or partially embedded in a random pattern that is non-reproducible. May come in a range of colours and shapes. Change their colour under UV light. | Magnetic elementsPattern of magnetic elements that generate a signal or a series of signals, which can be detected remotely by special identification devices. |
| Tactile patternsIntaglio printing producing a raised tactile relief, which can be authenticated under oblique light. May be combined with latent image. | MicroprintPrint using extremely small text that requires magnification to become readable with the naked eye. | Anti-Stokes inksInks with Anti-Stokes properties that can be examined using a video spectral comparator (VSC instruments). |
| HologramDisplay of a fully three-dimensional photographic recording of a light field with angle of observation. | Thermochromic inkHeat reactive ink that is sensitive to temperature change. Ink will change colour or disappear when exposed to temperature changes. | Reactive inks (covert)Colourless or transparent inks that become visible upon reaction with a specific solvent that is applied by means of purpose built tools under laboratory conditions. |
| Reactive inks (semi-covert)Colourless or transparent inks that become visible upon reaction with a specific solvent that is applied by means of a special pen or marker. |
