Abstract (en)
[origin: WO2012136597A1] The invention relates to an open optical security feature which provides for a high level of security and can be produced relatively straightforwardly in a technical production method. The security features of optically variable inks with tilt effect and the properties of a latent image are combined with one another and interwoven. By virtue of the security feature being generated by printing, the security feature can be realized in a cost-effective manner, but nevertheless with a very high level of security being provided. The resulting security feature can readily be verified at any time, by any desired individual, without any additional auxiliary means being required.
