This incredible ink changes colour when exposed to water or moisture!
Product Code: HYDROSPI1440
Hydrochromic screen-printing ink is a smart ink that changes colour in response to moisture. It’s typically white when dry but becomes translucent when exposed to water. This colour change occurs because the ink contains pigment molecules that react to changes in the water content of the surrounding environment.
How it Works:
The pigment molecules in hydrochromic ink are hydrophilic, or “water-loving.” When the ink is exposed to moisture, these molecules absorb the water and swell, causing the ink to become more translucent or transparent. This reaction is reversible, meaning the ink will return to its original colour once it dries out.
