Heat-sensitive inks

The heat-sensitive ink allows to execute original and genuine printing works thanks to its change of colour depending on the temperature. This ink provides printed texts or graphs with changes of colour depending on whether the temperature is cold or hot.

This ink can have its initial colour again when the change of temperature stops. It can also have a permanent colour change as needed.

We can print a visiting card that changes the colour of its texts or graphs when touching it. We can also produce a label that changes colour irreversibly when reaching a specific temperature, which allows to check, for example, that sliced bread has been appropriately baked in the oven.

Reversible heat-sensitive inks

Reversible heat-sensitive inks are suitable for producing original promotional items as products printed with this type of ink will have colour changes as needed. 
  • Labels for soft drinks or beer can be printed with cold-sensitive ink. Therefore, the colour of graphs will be different depending on whether the product is hot or cold.
  • Something as normal as a visiting card may become really original because when touching it, the colours of its texts change.
  • Games associated to the consumption of a product can be made as the prizes can appear with heat or cold.

This ink can be calibrated at a specific temperature between -10ºC y 69ºC approximately. There are certain standard temperatures and colours.

Irreversible heat-sensitive inks

This type of  heat-sensitive inks has a permanent change of colour, which means that they are single-use inks. This behaviour is ideal for controlling the temperature in processes such as baking or other heating processes. These inks can be calibrated at a specific temperature between  65ºC y 200ºC. There are certain standard temperatures and colours.

Printing methods of heat-sensitive inks

All our inks are printing inks.

Water-based irreversible inks designed for screen printing and flexography. They are designed for printing paper labels where texts or graphs are printed on, the colour of them will show if the process of the product labelled has had an appropriate heating process.

However, reversible inks are much more versatile in printing methods and formulations. They are in great demand and have numerous applications, mainly in the field of promotional campaigns, cosmetics and teaching. There are inks for flexography, screen, offset or rotogravure printing, among other methods. They are made of water, solvent, plastisol or epoxy and UV curing.

Materials that can be used with heat-sensitive inks

Versatility of formulations described in the section above provide heat-sensitive inks with numerous applications in multiple surfaces such as paper, wood, plastic, ceramic, or glass products.

We also offer pigments in tablets or in powder or paste form. With this pigment, end users can make their own formulations. This pigment can also be mixed up with plastics to make products that change their colour such as spoons for ice-creams, caps for drinks, etc.
