It's difficult to miss the recognizable purple-black ink mark left on voters' fingertips during the current indian elections. This ink, which is only produced by the karnataka government undertaking mysore Paints & Varnish Ltd., is essential in stopping fraudulent voting since it identifies voters who have already cast their ballots. With a 10 ml size, some 26.5 lakh tiny bottles of this permanent ink are made for every election cycle.
 
In indian elections, the practice of using permanent ink to prevent duplicate votes has long been practiced. Voters were required to have ink put on their thumb or finger before receiving their voting papers; this practice was first noted in the Representation of the people Act (RoPA) of 1951. This procedure persisted until the advent of Electronic Voting Machines (EVMs), which apply ink before voters cast their ballots by pushing a button. silver nitrate is an ingredient in the indelible ink, which is intended to withstand washing, liquids, and detergents for up to 72 hours after application.


Its production procedure and chemical makeup are closely kept secrets that only a few people know. To prevent election fraud, scientists at the Council of Scientific & Industrial Research (CSIR) first invented the ink in the 1950s. Since 1962, mysore Paints & Varnish Ltd. has been authorized to produce the ink.

The firm runs commercially and exports the ink to more than 25 nations globally, despite being a government project. It's interesting to note that different countries may have different uses for permanent ink. For instance, voters in the maldives and cambodia dip their fingers into the ink, but in Burkina Faso, a brush is used to apply it.
