INTELLIGENT PRINTING INKS
Our intelligent printing inks are manufactured by chemicals which are suitable for printing on the food packaging. In addition, transition of any substance through the printing substrate is blocked. That’s why our intelligent printing inks are suitable also for packaging of highly sensitive products.
Irreversible coloring change / permanent
Reversible coloring change / repetable
FULL TEMPERATURE CONTROL
We have the know-how for preparation of indicator labels for various applications, and if necessary we can further refine and upgrade the basic examples.
Active materials can be developed to change their colors at any single temperature between -30 °C and 100 °C, and can be further developed also for a wider area. Several color versions are possible to be provided.
A suitable graphic design can combine reversible and irreversible thermochromic elements, which increases the application possibilities and uniqueness of the indicator labels. They can be custom-made according to the needs of each technology and application.
Our basic product is an indicator label where an arbitrary design is printed using the intelligent ink. When heated above the controlled temperature, its color changes reversibly or irreversibly, depending on the active material used in the ink. The change is seen by naked eye, but can also be recorded with a video camera and included in an automatic control system.
The color of the indicator label with reversible color change indicates if the current temperature is exceeding the allowed value. Such labels enable visual control of the temperature without any supply or additional equipment.
Control of overheating is very important for temperature sensitive products such as food, pharmaceuticals, chemicals, seedlings and seeds. The overheated product has shorter shelf life and can also become hazardous to health.
Irreversible indicator labels enable controlling the temperature of each individual product in the cold chain, which may help to prevent errors and to reduce the amount of thereupon wasted products.
Different technological processes and in the case of some other occasions need heating to the target temperature and such process should be controlled. Irreversible temperature indicators developed for the particular needs and used on each individual product provide solid evidence that it was heated properly.
