How color drives the knockout

Chromalith classifies the garment color as dark, bright, or light and uses that group to set the preset's Levels. Dark garments give the widest separation. Bright garments compress tonal separation. Light garments flip which tones screen and which print solid. The note under the preset tells you which group is active.
