Gravure Process Color Gamut Optimization

There is an opportunity to optimize color gamut for process color printing before we address process control for repeatable color and color management for predictable color. Gamut optimization assumes that there is no applicable printing specification for an ink-substrate-press condition and it must be derived on its own merit. In this paper, we approach gravure gamut optimization from adjustments and compromises made in ink strengths, inkdown sequence and tonal gradation for packaging printing. The outcome leads to product differentiation between the optimized gravure press and other competing printing presses. Gamut optimization strategies are also discussed for other printing processes.
