Features
SAM
Screen Angle Modulation (SAM): this is a copy protection. It protects valuable documents from digital colour copies. The copy will include a line of text or the image will be disrupted, clearly showing that it is a copy.
μSAM
Copy protection with a screener. This is used to verify the authenticity of a document or a product label. The presence of the coding image is verified and decoded by means of a so-called μSAM screener.
MetaSAM
Combined security feature.
LIFT
A Li Frequency Trap (LIFT) is a screen replacer that protects the document from colour copies. The copy will include a piece of text which shows that it is not the original.
NoCopyCode
Authenticity certificate. Special barcode for CD, gift and book vouchers. Can also be used for access control. Readable by infrared checkout scanners.
SABIC
Digital watermark A normally visible (coding) image is modulated with a band of spatial frequencies that are too high to be seen by the human eye. The coding image will no longer be present in a copy. The coding image can be detected using special software algorithms in (commercial) scanners.
Dual Band Coding
Dual Band Coding (DBC) is a digital watermark that is based on a combination of SABIC and Full Spectrum. It can be used, for example, on labels for products and passports. Special scanning equipment is required.
Full Spectrum
Digital watermark that is used to establish the authenticity of the image on a valuable document. The coding image is inserted in a regular, visible image. The document can be personalised and traced. It is only suitable for machine detection.
ISOGRAM®
At first sight, ISOGRAM® looks like a regular illustration or photograph. In reality, it is a coding image in a normally printed (possibly multi-coloured) half-tone image. This technology does not affect the visible part of the half-tone image and it can be implemented in nearly every design. After copying, the coding image will no longer be present in the copied document.
DAR
A special coating for banknotes to increase their durability (by over 80%). The development of DAR started in the late 1950s. Since the 1980s, this varnish has been used on Dutch banknotes with an unchanged composition. Tests and publications have shown that DAR almost doubles durability. This means that reprints can be ordered at a much later stage – resulting in a considerable cost reduction.
DAR Integrated Systems
Not every machine is able to coat banknotes with DAR at the same level of efficiency. Joh. Enschedé is glad to help other high-security printing businesses if they wish to purchase and familiarise themselves with suitable coating machines. This takes place on a consultancy basis; no licence restrictions apply.
JE-BRC
Secure barcode for banknotes, readable by checkout scanners. This can also be used for gift vouchers, travel documents and ID documents.
JE-SSP
Copy protection for banknotes that can be clearly recognised by the general public.
Licensing
It is possible to acquire a licence for these features from Joh. Enschedé. Please contact sales@joh-enschedé.nl for more information.
