TH’INK™ is a heat responsive thermal ink developed by Colour Flux for applications where reliable thermal printing and clear visual change are required. The ink is BPA and BPS free, making it a safer and more environmentally responsible alternative to conventional thermal inks.

When exposed to heat, TH’INK™ produces a visible colour change. In addition to the traditional white to black reaction, the ink is available in green, red, yellow, and blue, allowing manufacturers and printers to select the most suitable colour for their specific application. This flexibility makes TH’INK™ suitable for both functional and identification purposes, where colour differentiation is important.

TH’INK™ is widely used in the production of linerless labels, where consistent thermal response and clean print quality are essential. It is also used in security and tamper evident bags, where thermal printing is part of traceability, labeling, or authentication processes. More broadly, the ink is suitable for any industry that relies on thermal printing, including logistics, packaging, retail, and industrial labeling.

The ink has been formulated to be easy to apply across a wide range of substrates. It is compatible with all common printing methods used in industrial production, including flexographic and screen printing. This makes integration into existing printing lines straightforward, without the need for special equipment or complex process adjustments.

In addition to its performance, TH’INK™ is designed with environmental considerations in mind. Being BPA/BPS free and eco-friendly, it supports manufacturers looking to reduce the environmental impact of their printed products while maintaining consistent thermal performance.
