Explore the Possibilities:
Hydrochromic Ink: Reveal Hidden Secrets with Water
Uncover hidden messages, images, or colours with our reversible Hydrochromic Ink. This white ink becomes translucent when it comes into contact with water, revealing the layer beneath. Once dry, it returns to its original opaque state, ready for the magic to happen again and again. Perfect for interactive designs, surprise reveals, and educational projects.
Thermochromic Ink: Colour Change at Your Touch
Experience the wonder of temperature-sensitive colour change! Our Thermochromic Ink is ideal for concealing hidden images, text, or colours. When exposed to temperatures above 27°C (achievable with warm hands, a hairdryer, or a radiator), the ink becomes transparent, revealing what's beneath. This versatile ink, supplied with binder, opens up a world of innovative applications, from colour-changing clothing to temperature-sensitive packaging.
Photochromic Ink: Colour that Comes to Life in the Sun
Watch colours magically appear with our Photochromic Ink! This seemingly colourless ink transforms dramatically when exposed to direct sunlight, revealing a vibrant hue. The colour change is fully reversible, allowing you to enjoy this captivating effect time and time again. Perfect for outdoor applications, sun-reactive designs, and creating eye-catching novelties.
Super Glow-in-the-Dark Ink: Illuminate the Night
Add a touch of luminous magic to your projects with our industry-standard Super Glow-in-the-Dark Ink. This powerful photoluminescent ink boasts a strong glow and long-lasting afterglow. After just ten minutes of charging in daylight, this white ink emits a bright green glow in the dark. Exclusively for fabric use, this ink is ideal for creating glowing apparel, safety garments, and captivating nighttime designs.
