Nanotech launches ‘KolourDepth’ feature, fills ‘OTF’ orders

Canada’s Nanotech Security Corp., a researcher and producer of nano-optic structures and colour-shifting materials, recently announced the launch of its “KolourDepth” banknote security feature.

Its visual effects include “3D, colour and movement,” according to a statement issued by the company earlier this month. The combination of nano-scale origination, proprietary algorithms and specialized manufacturing techniques are used as a form of counterfeit deterrence. The feature also reportedly allows for better-designed security elements that “tell rich and memorable stories, intuitively capturing and holding a person’s attention as the banknote is inspected for authenticity.”

“We have developed an innovative security feature that is intuitive to trigger and highly customizable. In addition to striking overt security effects like multiple 3D elements, multiple colour images, omnidirectional movement, and overprinting, KolourDepth can enhance a feature by also adding microtext, nanotext, nano-imagery, and machine readability,” said Troy Bullock, Nanotech president and CEO.

“KolourDepth is based on our KolourOptik nanographic display platform which is the foundational technology behind all our leading-edge nanotechnology products. In recent months, the Company has focused on aggressive product development and commercialization of our technology. KolourDepth represents another important milestone in Nanotech’s growth.”

Nanotech also announced new orders for its “optical thin film” (OTF), which is used in the banknote, secure documents and brand protection markets.

The first order, announced in August, is from a confidential “key long-term customer” while another two orders, announced in September, are from “a major banknote and secure document integration supplier.”

The specialized film, which is made at Nanotech’s secure operations in Thurso, Qué., uses layered thin-film materials to create an overt colour shift during the authentication process.

The company was also recently granted three new nanotechnology patents.
