GAMMA (MIDS) 1.00
Push black point up to slam the subject solid black; lift gamma to keep the background as airy greys — the Keaton look.
Separation Basis CS
SPLIT FREQUENCY 0.12
BAND SPREAD 2.2×
DETAIL GAIN 0.50
FFT splits by spatial frequency: low band → light ink (smooth tonal masses), high band → dark ink (edges & fine detail). Expressive, not tone-calibrated — tune live against the composite.
Inks
Each ink owns a tonal band; tones derive from each swatch's lightness. Inks auto-sort dark→light. Edit a swatch to recolor.
OVERPRINT BLEED 0%
0% = knock-out (inks tile edge-to-edge). Higher = lighter inks underprint beneath the darker ones — richer overprinted tone, forgiving of misregistration. Print in screen order (1 first).

GRAIN JITTER 0.90
CLUSTER SCATTER 0.50
EDGE ROUGHNESS 0.55
Lower LPI = chunkier dots that burn & print easier on coarse mesh. Dot gain shrinks dots to compensate for ink spread on press.
