While most CTI technologies revolve around temperature and light, we also have technology that develops color with pressure. For instance, rubbing a coin on a printed label can reveal a hidden message used for authentication or simply for fun – like playing tic-tac-toe. More seriously, high pressure-activated technology delivered through a commercial HPP ink to verify High Pressure Pasteurization (HPP) offers a quick visual way to sort packages that haven’t been HPPed, offering an extra quality check before hitting grocery shelves.
Quick visual indicator
Printable technology, just like other high speed commercial inks
Full control over brand identity, graphic design and placement, either through existing printed label or direct package/container printing
Use with QR codes that are scannable or unscannable, depending on the product state
Fractions of pennies per package
Tunable targets with high-volume implementations
Long-term chemical stability
Safe for indirect food contact
BPA-, BPF-, BPS-free and compliant with REACH, Prop 65, CONEG, and many other regulations.
High Pressure Pasteurization (HPP) Ink Indicators:
HPP ink has transformed the food industry, allowing juices, dips, ready-to-eat meats and more to be safer, look and taste better, and enjoy longer shelf life. But a non-HPPed package looks exactly the same as one that’s been HPPed — until now. CTI HPP Indicator Technology shows if a product has been through HPP and can be applied to packages with a printable commercial ink or preprinted labels.

HPP pressure verified
Here are available HPP technology indicator “recipes” – combinations of pressures and operating environments:
Quick Code: W-1
Broad indicator for the warmest operating conditions and anything above 50,000 PSI.
Target HPP Pressure: 50,000 PSI
Operating Chamber Water Temp: 15–20°C
Quick Code: W-6
Best all-around indicator differentiating between 70, 80 and 87,000 PSI.
Target HPP Pressure: 87,000 PSI
Operating Chamber Water Temp: 10–15°C
Other formula recipes may be available – contact CTI to find out more.
Industries and Applications
Foods Flexible packaging and containers for ready-to-eat meats, sauces, soups, salsas, hummus and beverages – anything that may be put through the High Pressure Pasteurization process.
UV Flexo, Water-Based Flexo, Solvent-Based Flexo and Gravure, UV Wet Offset, UV Dry Offset. Other print formats may be available.
This printed technology changes from clear to the target color when a user applies pressure, using a coin or other hard surface.
Industries and Applications
Foods Traceability and authentication for food labels and packages. Good-seal indicator for films on plastic containers. Hidden control numbers.
Industrial Color indicator to show a good seal between tape and surface (slide painter’s knife or scraper across the tape).
UV Flexo, Water-Based Flexo. Other print formats may be available.
High-Pressure activated ink technology requires detailed understanding of the application and only may be purchased after completing a requirements assessment and qualification trial.
