CMYK process separation mixes 4 main colors (cyan, magenta, yellow,
black) to produce a full color image. This technique is commonly used
in offset printing. When screen printing with process inks some colors
like orange, bright red, and green are difficult to reproduce and may be
generated by additional screens in order to reproduce a vivid print.
Top white may also be used in order to help blend colors and give the
image a pop.
CMYK True Process Separations
Unlike the above separation techniques, CMYK process
inks are transparent and can only be printed on light or white
garments. Although process prints have be reproduced on darks using
underlays, I recommend printing with simulated process on darks to
achieve a brighter more consistent print.

Process seps need different screen angles then the other techniques.
1. Yellow - 75 degree screen angle
2. Magenta - 45 degree screen angle
3. Cyan - 15 degree screen angle
4. Black - 75 degree screen angle
5. Hilight white - 15 degree screen angle
6. Spot colors - 15 degree screen angle
LPI - 55-65
Dots - Elliptical

1. Base white plate - 230 mesh
2. All CMYK gradient plates - 255 mesh
3. Spot color plates - 180 mesh
