Anti-copy raster
This security feature is especially designed to protect against copying. Certain pixels disappear when copied.

Barcoding
In addition to allocating issuing offices, 1D barcodes enable stock-controlled or electronic role administration. 2D barcodes have a higher storage capacity than 1D barcodes, for tariff information, for example.

Blind embossing
Blind embossing can be used e.g. to accentuate a company logo by warping the paper.

Copy protection ink, bright orange
Bright orange copy protection ink is a luminous ink and reflects under UV light (so-called black light). Forgeries and manipulation are not possible when bright orange copy protection ink is used, as the colour changes to ‘brown’ when scanned or copied.

Diffraction foil
Diffraction foils are readily available foils with a „holographic“ effect. As we are dealing with standard images here, diffraction foils are less expensive than a hologram foil. The security level of diffraction foils can be upgraded by designing them with customised images.

Guilloches
Guilloches are fine, interwoven lines (line network), which can only be produced in time-consuming pre-press processes. When combined with bright orange copy protection ink, the guilloches’ security level can be further upgraded. The combination of guilloche and bright orange cannot be scanned or copied.

Iris print
Iris print is a simple but non-reproducible colour print technology. In this printing method, colours merge together during printing.

Microline
A microline is an ultrasmall font, which can only be viewed under a magnifying glass. Microlines cannot be copied or printed using standard printers. For logical reasons, the microline is integrated into the travel ticket layout on the edge of the roll. Copying and scanning protection is enhanced by printing the microline in bright orange copy protection ink.

Mottling fibres
Mottling fibres are incorporated into the travel ticket paper and reflect under UV light. Optimum protection against forgery can be obtained using invisible mottling fibres, which only glow under UV light and therefore cannot be scanned or copied.

Numbering
Roll and ticket numbering is useful in tracing rolls and tickets. The numbering, normally printed on the reverse side of the ticket, provides information about issuing offices, depots or transport companies. As number ranges can be “blocked”, it is possible to allocate stolen travel tickets immediately.

Optically variable printing inks (OVD)
These are printing inks which change their colour, depending on the angle from which they are viewed. This extremely high-level security element is used, amongst others, in the production of passports and banknotes.

RFID
Stands for Radio Frequency Identification. This contactless identification procedure is based on radio frequency technology. The transponder located in the RFID card is used for storing or processing data.

Sinus lines
Sinus lines are irregular wavy lines, which for logical reasons, are printed on the reverse side of the ticket. Due to their irregular lines, sinus lines prevent blank sections of the ticket from being linked together and thus prevent it from being manipulated. The security level of sinus lines can be enhanced by printing them in bright orange copy protection ink.

Standard hologram/customised hologram
Individual or strip holograms make tickets unique and secure against manipulation and forgeries. In addition to standard holograms, customised holograms can also be created.

Steel engraving
Steel engraving is a haptic security feature. This is a printing procedure that is used for printing banknotes and passports.

Transparent fluorescent inks
Transparent fluorescent inks are on a so-called „2nd level“. These can only be detected under UV light. It is therefore impossible to manipulate or forge documents by copying or scanning them.

Watermarks
Watermarks are images, lettering or symbols which are created during the paper manufacturing process and are inserted into paper through different paper thicknesses. The watermark is visible when held up to the light.
