Security fibres have been widely used for years to increase the security level of paper-based documents. ANY Security Printing Company PLC produces security fibres of varying sizes and colours on polyamide and viscose bases. Our offering includes various coloured and colourless, fluorescent and non-fluorescent fibres of varying length and Dtex numbers, which can be made of either polyamide or viscose. Generally, we recommend the use of two or more different flocculants within one document and of course, we are at our customers’ disposal to develop combinations that suit their needs.
