Colours i GSM — Why It Matters GSM (grams per square metre) is the most critical value in this calculation. Default is 1.2 g/m² — a reasonable litho starting point. Heavy inks (dense blacks, deep spot colours): 1.4–1.8. Transparent/process inks: 0.8–1.1. Always verify against real job data for accuracy.
