Unilever is reducing the number of ink colors on its European food packaging from more than 100…to just six. The program, an effort to drive down costs and simplify the supply chain, comes after the brand owner piloted a successful ink-reduction program across its spreads and cooking categories. The new six-color palette is said to be capable of replicating all of the colors in the brand’s entire food packaging range, offering the additional benefit of reduced material waste and, as a result, of minimized environmental impact.
