Sense and Sensibility

Converters benefit from Rub'n'Smell inks, too. The inks print in-line like any other kind of ink or overprint, directly over printed graphics, making it a simple addition to packaging, Berard said. Also, he said, "The scent stays stable for years once printed."

Rub'n'Smell inks are activated only when gently rubbed. They contain fragrance oils that are microencapsulated using FOLCOScent® technology, which uses patented synthetic polymers for the microcapsules. The inks can be run in-line for offset, flexo, and gravure print applications.
