Our innovative message-hiding technique involves embedding a message within a tailor-made camouflage pattern. We then use thermochromic ink to reveal the message, which reacts to temperature changes. The process involves using color-matching ink for the visible parts of the message while using thermochromic ink for the remainder. At your target temperature, the thermochromic ink disappears, revealing the hidden message or image within the pattern.
Our high-temperature thermochromic ink creates pure coffee magic. The ink disappears as your hot coffee reaches its target temperature, revealing the hidden message. Not only is this technology exciting, but it’s also functional.
