Question:
What is considered "gray" in the CMYK and RGB color spaces?

Answer:
CMYK is considered “gray” when C=0, M=0, Y=0 and K is greater than 0.
RGB is considered “gray” when R=G=B

A very useful Fiery feature using these definitions is “Print Gray Using Black Only”

Feature: Print Gray Using Black Only (CMYK)
Options: Printer’s default / Text/Graphics / Text/Graphics/Images
Enable this option if you want to use only black toner when printing the specified “gray” CMYK objects (text, graphics or images).

Feature: Print Gray Using Black Only (RGB)
Options: Printer’s default / Text/Graphics /Text/Graphics/Images
Enable this option if you want to use only black toner when printing the specified “gray” RGB objects (text, graphics or images)
