Inks
LCR Hallcrest produce Thermochromic, Hydrochromic, Photochromic, Flash Reflective and Liquid Crystal Inks, Coatings and finished items that change colour.
*Chameleon® Thermochromic Inks & Coatings change colour in response to fluctuations in temperatures, from sources which are hot cold ambient or body temperature.. There are reversible and irreversible types.
*Liquid Crystals are highly responsive to temperature change, quickly changing colour reversibly as they are warmed or cooled. The usual appearance of these inks is against a black background where they reveal spectral colours (from red through greens and blues) when warmed,.
*Photochromic inks change colour when exposed to ultraviolet light usually from the sun (or a uv black light), from colourless indoors to vibrant colour outdoors.
*Chameleon® Hydrochromic Inks & Coatings react to the presence of water. We make Reversible and Irreversible Hydrochromic Inks.
*Flash reflective ink is transparent and becomes visible in flash photographs on mobile phones, and bright beams of light.

Thermochromic
REVERSIBLE:
Chameleon® Thermochromic Inks & Coatings change colour gradually in response to fluctuations in temperatures. There are both irreversible and reversible types.
Uses of these products generally fall into three areas: COLD, BODY and HOT and are used to enhance labels and packaging, give warnings, advise correct food and drink temperature, show proof of authenticity or simply act as an interactive game mechanism on labels, cards and coasters.
Heat activated – These change from a coloured state at room temperature to a translucent colourless state when heated and can reveal messages or pictures beneath. Often used for Touch & Reveal or Rub & Reveal interactions. They revert back to their coloured state on cooling.
Cold Activated – These are colourless at room temperature and become coloured or reveal a message when chilled, becoming colourless again when warmed.
IRREVERSIBLE:
These inks change colour permanently when activated by increases in temperature from a colourless to a coloured state. The reaction is irreversible. We can produce screen or flexo systems.

Liquid Crystal
Chameleon® Liquid Crystals are highly responsive to temperature change, quickly changing colour reversibly as they are warmed or cooled.
The traditional presentation of these inks is against a black background where they reveal spectral colours (from red through greens and blues) when warmed, although other coloured backgrounds will influence and alter the resulting colours viewed.
USED FOR SPECIAL COLOUR CHANGING EFFECTS
Liquid crystal inks are mainly used for special colour changing effects, often tailored to react at body temperature when touched. Applications also include presentation packaging, book, CD and record covers, flooring panels, leather products and feet measuring pads. Additionally we produce highly accurate finished thermometers which are used in many applications from Fever Thermometers to monitoring Fridge Temperatures. (see other website sections).

Hydrochromic
Chameleon® Hydrochromic Inks & Coatings react to the presence of water. We make Reversible and Irreversible Hydrochromic Inks.
These products can be used in applications revealing that a product has been exposed to water, such as a mobile phone, through to interactive game cards that reveal images or messages either reversible or permanently.
IRREVERSIBLE:
We produce two types of ink.
The first changes from a colour to clear (or white, if printed onto white substrate) when exposed to water and remains so when dry again.
The second dissolves and washes off the surface revealing a message below.
These irreversible inks are available in Blue and Black.
REVERSIBLE:
This ink is white in appearance but becomes translucent when exposed to water and then reverts back to a white state when dry.
The reversible ink is available in white only.

Photochromic
Chameleon® Photochromic inks change colour when exposed to ultraviolet light usually from the sun or a black light. The inks are effectively colourless indoors and turn into vibrant colour outdoors.
When brought back inside, the inks become clear again. The inks become intensely coloured after only 15 seconds in direct sunshine and return to clear after about 5 minutes indoors.
Key features
- Near Invisible when not exposed to UV Light
- Fast Reversible Transition – Intense colour in 15 seconds returns to clear after 5 minutes indoors
- A range of standard colours
- See individual product data sheets for a list of available stock colours
- Available for print on textiles (plastisol or water based) and board (water based)
- Washable without chlorine
- Image Transformation-Hidden Messages – Game Pieces – Black and White outline to Colour images
- Textiles – Glassware – Ceramics – Plastics
