Interactive Inks & Print

Interactive and versatile, we can produce Thermochromic, Hydrochromic, Photochromic and Liquid Crystal Inks and Coatings. These have proven to be ideal for mailers, leaflets, game cards, children’s stickers and collector cards, magazine covers, educational question & answer cards, on-pack/off-pack promotions, coasters and P.O.S material.

Any area can be covered by our ink and the clarity of the revealed image is excellent. Our Inks have been used in many successful international promotions such as Douwe Egberts, Haagen Dazs, Budweiser and Coors.

Interactive Plastics

Years of research have resulted in our range of quality Thermochromic , Photochromic and Phosphorescent resins, leading us to winning a Millennium Product Award.  Due to their unique abilities the temperature sensitive materials change colour as the temperature changes, or with photochromic masterbatch when it is exposed to UV light.

Our Advanced Chromatic Technology provides superior colour quality and durability, resulting in products that can create a colour change effect repeatedly over time.  With an extensive range of colours we can create almost any colour required!

What’s new at Colourchange?

Stir down the temperature with Chocomel colour changing stirrers

Working closely with leading Dutch agency, Miles Promocean on their recent and on-going colour changing stirrer promotion for well known drinking chocolate brand, Chocomel which is taking place nationwide within the Netherlands and soon to be followed by a campaign in Belgium too.

Chocomel is extremely popular as a warming winter drink, and this new campaign with the branded colour changing stirrers is promoting Chocomel as a cool refreshing summer drink.

The Chocomel colour changing stirrers are being used as POS material in restaurants, as an awareness campaign to encourage restaurant staff to serve Chocomel chilled to consumers, and to show consumers that the drink is really refreshing when drunk chilled, at 4°C for optimum enjoyment – its cool drinking temperature.

Chocomel is served to consumers in a stainless steel cup along with the stirrer which changes colour vividly from yellow to orange to indicate that the drink is cold. The colour changing stirrers include a thermometer relief within the design showing 4°C – the perfect temperature to drink Chocomel. The campaign is further supported by posters and pos material within the restaurant to encourage purchase.
