 Herbert used his chemistry knowledge to systematize and simplify the company's stock of pigments and production of colored inks; by 1962, Herbert was running the ink and printing division at a profit, while the commercial-display division was $50,000 in debt; he subsequently purchased the company's technological assets from the Levine Brothers for $90,000 () and renamed them "Pantone".The company's primary products include the Pantone Guides, which consist of a large number of small (approximately 6×2 inches or 15×5 cm) thin cardboard sheets, printed on one side with a series of related color swatches and then bound into a small "fan deck".For instance, a particular "page" might contain a number of yellows of varying tints.
