Tamperproof Images Protect Packaging And Documents

Datalase has launched the Guardmark tamperproof encapsulated imaging system for protecting and authenticating primary packaging and security documents.

Datalase has launched the Guardmark tamperproof encapsulated imaging system for protecting and authenticating primary packaging and security documents.

Formerly part of the Digivu suite of systems, Guardmark combines proprietary chemistry, a variable energy laser source and an individual control system to produce claimed high resolution, overt, semi-covert and covert images for document and brand protection.

Datalase commented that the counterfeiting market continues to grow and it is estimated to have surged towards US$1 trillion in 2004 and be worth 10 per cent of world trade.

Tools that can protect brands are, therefore, a valuable weapon in the continuous fight against fraud.

According to Datalase, Guardmark provides brand manufacturers with a safe, secure and highly-effective way of preventing forgery.

It is claimed to allow manufacturers to apply different levels of protection to their brands using a single product.

Microscopic scale images with a resolution up to 10,000 dots per inch (dpi) can be applied directly to the surface of a product, become embedded in its substrate, or within laminate films surrounding it.

The process is capable of forming images directly between the layers of a clear laminate film or self-adhesive label whilst retaining the integrity of the uppermost layer.

The company added that image permanence and tamper resistance are guaranteed.

Datalase believes that Guardmark provides three levels of protection.

Firstly, it enables the covert marking of products with images, such as micro photographs and text that can be magnified and visually compared.

It is said to also allow encrypted data to be scanned and machine verified and that hidden images can be forensically analysed and laser marked.

The variable digital imaging process can be applied to any substrate, including general packaging materials, plastic, metal and glass, it is claimed.

Datalase's authentication technology was awarded the outstanding achievement in anti-forgery technologies at the Product and Image Security Convention (PISEC) 2005 in Vienna (Austria).
