Smart Ink Trial Pack: Unlock the Creative Potential of Colour-Changing Inks

This comprehensive trial pack provides a gateway to the innovative world of colour-changing inks. Experiment with four unique formulations – thermochromic, photochromic, hydrochromic, and glow-in-the-dark – and discover their potential for a wide range of applications across diverse surfaces.

Kit Contents:

  • Thermochromic Ink Black 27°C (25ml): This remarkable ink undergoes a dramatic transformation when exposed to temperatures above 27°C. At room temperature, it appears as a deep black, effectively concealing any underlying design. However, upon reaching the activation temperature – easily achieved through touch, a hair dryer, or other heat sources – the ink transitions to a transparent state, unveiling the hidden layer beneath. This dynamic ink is perfect for creating interactive designs, revealing hidden messages, or adding an element of surprise to your products. (Includes 25ml binder for optimal performance)
  • Photochromic Ink (25ml): Harness the power of sunlight with our photochromic ink. This intriguing formulation appears virtually colourless when applied, seamlessly blending into the background. However, when exposed to direct sunlight or UV light, the ink undergoes a remarkable transformation, revealing a vibrant burst of colour. Choose from a spectrum of captivating shades, including magenta, orange, blue, yellow, or green, to create designs that react dynamically to their environment.
  • Hydrochromic Ink White (25ml): Unleash the magic of water with our hydrochromic ink. This unique ink appears as a crisp white when dry, effectively concealing any underlying design. But when water or moisture comes into contact with the surface, the ink loses its opacity, becoming translucent and revealing the hidden layer beneath. This captivating effect is reversible, with the ink returning to its original white appearance as it dries, making it perfect for creating interactive designs, surprise reveals, or moisture-sensitive applications.
  • Super Glow Ink Green (25ml): Add a touch of luminescence to your creations with our Super Glow Ink. This phosphorescent ink appears white in daylight, seamlessly blending into the background. However, after being "charged" in daylight or under a UV light source for approximately 10 minutes, the ink emits a vibrant green glow in the dark. This captivating effect can be recharged repeatedly, providing endless opportunities for creative applications.

Application Versatility:

These innovative inks can be applied to a wide variety of surfaces, including:

  • Fabrics: Ideal for creating interactive apparel, promotional items, and textile designs.
  • Paper and Card: Bring brochures, packaging, and marketing materials to life with dynamic colour-changing effects.
  • Wood: Add a unique touch to wooden crafts, signage, and decorative items.
  • Ceramics and Glass: Create stunning designs on mugs, bottles, and other surfaces.
  • Plastics: Enhance the appeal of plastic products with interactive colour changes.

Application Methods:

For optimal results, we recommend the following application methods:

  • Screen Printing: Achieve precise and detailed designs using a 43T mesh screen and a medium shore, square squeegee.
  • Spraying: Apply the inks evenly to larger surfaces or intricate shapes using conventional spray equipment.

Coverage:

A 35ml application of ink typically covers 1 square metre per coat, allowing you to achieve vibrant and impactful results.
