What began in a Cornell University lab in 1993 has grown into a globally recognized powerhouse of innovation in chromatic ink technologies. CTI, headquartered in Colorado Springs, holds more than 20 patents and has introduced 35 unique technologies, including thermochromic (heat), barochromic (pressure), hydrochromic (water), photochromic (light) and glow-in-the-dark inks. These technologies power some of the most engaging consumer packaging solutions in the world. Today, CTI serves clients in more than 60 countries, delivering products that engage consumers.
CTI’s success lies in its ability to transform complex chemistry into practical applications for consumers across industries. Its encapsulated dye technologies enable interactive designs that captivate audiences, boost sales and provide functional benefits across consumer packaged goods, healthcare and industrial markets.
“Our mission is simple: create chemistry that alerts, protects and surprises. From visually stunning designs on consumer goods packaging to technologies that ensure precision and safety, CTI drives meaningful innovation,” CEO Daniel Wachter says.
Showcasing Innovation in Action
CTI’s most iconic and enduring application is the thermochromic technology used on Coors Light cans. For 17 years, this feature has captivated consumers by turning the Rocky Mountains blue to indicate that the beer is cold and ready to enjoy.
In late 2024, Keurig Dr Pepper launched a limited-edition Dr Pepper NOLA can in Louisianna, featuring CTI’s hybrid printable technology. New Orleans artist Becky Fos created a design showcasing the Caesars Superdome, the host of Super Bowl 2025.
Fos says, “This can perfectly reflects my art, which is vibrant and ever-changing — just like this innovative technology.”
Lisa Griggs Hughes, commercialization & activation manager for Keurig Dr. Pepper agrees; “Partnering with CTI Technologies and local New Orleans artist Becky Fos, we were able to activate a color-changing can that reflects the colorful culture of The Big Easy and Dr Pepper.”
CTI also has collaborated with General Mills on its GoGurt kids snacks brand to create thermochromic and glow-in-the-dark designs for its packaging, depending on the season.
In partnership with Sika USA, CTI developed the Pro-Weld™ visual indicator, a thermochromic technology that changes color from blue to clear when proper seam-welding temperatures are achieved during roofing installation. This groundbreaking technology ensures optimal welds, reducing errors and preventing potential leaks.
“When we began this journey with CTI, our goal was to bring a totally new innovation to the commercial roofing market,” says Bill Bellico, vice president of marketing & inside sales at SIKA. “With Sika Pro-Weld, developed in partnership with CTI, we’ve delivered a game-changing product that makes installations easier, safer and more reliable.”
Expanding Opportunities with Strategic Partners
LA Libations, an incubator and beverage innovation company based in Los Angeles, has integrated CTI’s technologies into its portfolio of creative offerings. This will help established and emerging beverage companies differentiate their brands through packaging innovation. Recently, LA Libations launched its own Ultra Purified AlkalineWater with Electrolytes in Southern California, featuring thermochromic palm tree graphics that change color when the water is cold.
“This is the best-kept secret in food and beverage packaging innovation,” says Danny Stepper, co-founder and CEO of LA Libations. “CTI’s patented technologies unlock breakthrough differentiation for brands.”
The Hybrid Printable Technology Revolution
CTI’s hybrid printable technology is a game-changer in interactive packaging. By combining thermochromic and photochromic properties, it creates four distinct color profiles:
- One color indoors at warm temperatures;
- A second color indoors when cold;
- A third color outdoors in sunlight; and
- A fourth combination of colors when cold and exposed to sunlight.
This technology unlocks endless possibilities for creating dynamic, consumer-friendly packaging and promotional materials.
A Commitment to Sustainability and Collaboration
Four key pillars guide CTI’s innovations:
- Advanced chemistry — developing pioneering encapsulated technology;
- Innovations in interactivity — creating unforgettable consumer experiences;
- Sustainability — prioritizing eco-conscious practices in ink development; and
- Global reach — serving diverse clients worldwide.
Through close collaboration among its R&D, operations and commercial teams, CTI ensures high-quality, regulatory-compliant and sustainable solutions for its partners. Recently, CTI earned formal recognition from the Association of Plastic Recyclers (APR) for its CTI solvent-borne glow-in-the-dark and thermochromic products and UV-curing glow-in-the-dark and thermochromic products. CTI’s printable technology is the first of its kind to be evaluated by the APR organization, earning recognition for meeting or exceeding the APR Design® for Recyclability Recognition standards, demonstrating CTI’s commitment to sustainability and responsible design and to customers and partners.
“CTI has been a trusted innovation partner to [consumer product goods] brands for decades,” says Maria Del Rio, CTI chief marketing officer. “We help brands differentiate and engage consumers at the point of sale and during use. From Coors Light to Dr Pepper, our technologies deliver measurable impact.”
With more than 31 years of scientific innovation, CTI continues to redefine what’s possible in ink technologies, from beverage packaging to industrial applications and more.
