Frequently Asked Questions
Commercial offset presses and digital giclée printers use fine screen rulings (usually 133 to 150 lines per inch). Applying the Nyquist frequency principle, digital input must provide twice the line screen frequency (2 × 150 = 300) to reproduce crisp gradients without banding.
