Thermochromic Ink Reversible - Cold
Description
Temperature reactive ink; virtually invisible above a given temperature, it becomes coloured below this temperature and vice versa. This thermochromic effect at 31°C enables documents such as luncheon vouchers, gift tokens or holiday cheques to be authenticated thanks to a change of colour at body / finger temperature. This ink can also be used as a temperature indicator on packaging and labelling as a consumer guide to the correct conditions for consuming or using a product: coolness (example 15°C) control.
Cold reactive-irreversible ink is colorless when printed. When it is exposed to cold below 15°C sharp color appears and does not disappear once the temperature is increased. This feature helps protect documents or sealed envelopes from being tampered.
Application
Banknotes, Passports, Tamper-Evident Labels, Product Authentication, Stock Certificates, Postage Stamps And Identity Cards, and other goverment and applicable sectors documents or products etc.
