What does the posterize effect do?

It reduces smooth RGB tone changes to visible steps, creating flatter color regions and deliberate banding.

Where is Posterize in Ether-MOSH?

Open the FX panel, choose Color, and add Posterize. Its controls are Levels from 2–16 and Bias from 0–1.

What Posterize settings should I start with?

Start at 5 Levels and 0.50 Bias, then lower Levels for bolder blocks or move Bias slightly to rebalance shadows and highlights.

Is a posterized export ready for spot-color printing?

No. It is still an RGB raster result. Use it as artwork, then prepare actual separations, profiles, and proofs with your printer or prepress workflow.

Levels cuts the tonal budget, Bias moves the layoffs, and your formerly smooth portrait would like a union representative before the next export.

Quick answer

The posterize effect compresses smooth color into coarse tonal steps. Ether-MOSH quantizes each RGB channel with Levels from 2–16, while Bias shifts where those bands fall before quantization. Start at 5 Levels and 0.50 Bias. Lower Levels makes bolder blocks; moving Bias below or above 0.50 favors darker or lighter output.
