FLEXO Magazine : March 2011
16 Compatibility is the question when the fate of a print outcome lies in balance. Engineered substrates and high-performance inks are designed to facilitate productivity, so today’s material options continue to push boundaries. The commodities are versatile, valued and not to be wasted. In this edition, a large and extensive cadre of authors tackle the issue of selecting the right combination of ink and substrate for the right job. Their collective mission: Explain how to improve quality, trim costs, control waste, maintain consistent color and promote fast changeover.
