A tactile security feature for a banknote and a method for its production using in-line on a web-based process are disclosed. The security feature comprises a printed indicia layer including a design element and a printed enhanced tactility layer, which has at least a first enhanced tactility area overlapping the design element, such that the design element appears to have tactility due to the overlap with the enhanced tactility area. Preferably the tactile layer contains tactile particles. In addition, a banknote produced by the above method, a banknote having a single-ink system, and a coating for banknotes including a tactile security feature are disclosed.

The present invention is related to the filed of optically variable security elements comprising a region based on a single cured ink comprising a cholesteric liquid crystal polymer, said region having at least two, preferably at least three, patterns exhibiting, at at least one viewing angle, a different CIE (1976) color index parameter and/or a different position of the selective reflection band for protecting security documents against counterfeiting and/or illegal reproduction. In particular, the present invention relates to processes for manufacturing said features, when the processes comprises the steps of a) applying on a substrate by a rotogravure process with the use of a gravure cylinder having at least two, preferably at least three, different engravings a single cholesteric liquid crystal precursor composition, b) heating the applied composition to bring said composition to a cholesteric liquid crystal state, and c) curing the composition so as to form the region based on a single cured ink comprising a cholesteric liquid crystal polymer.
