The CMYK Halftone node produces a halftone-type result (figure 2). CMYK Halftone is a printing technique the reproduces color images by breaking the image into dots of varying sizes for printing with CMYK printing inks.

CMYK Halftone Parameters

Input Texture - Defaults to a solid color but provides a socket for an input texture. 

Base Color - Defaults to a solid color but provides a socket for an base input texture. The base color will be more visible as the Input Texture color approaches black

Halftone Mask Projection - Projection used to generate the halftone masks.

Mask Pitch - Distance between the rows or columns of dots in the halftone mask. 

Aspect Ratio - Aspect ratio correction for the halftone mask. 

Mask Angles - Halftone mask angles for C, M, Y, K respectively.

Ink Absorption - The proportion of light which gets absorbed with full K coverage or full CMY coverage. 

Gray Component Removal - Replaces a proportion of common CMY coverage with K coverage.

Under Color Removal - Replaces common CMY coverage with K coverage in dark areas of the image. Values greater than 100% will apply this to increasingly brighter areas. 

Rich Blacks - Uses a combination of K and CMY coverage to get deeper blacks than possible with 100% K coverage.
