Grayscale

Grayscale uses 256 shades of gray to represent an object.
Every Grayscale object has a value ranging from 0 (black) to 255 (white). The values between 0 and correspond to points on the grayscale spectrum.
Grayscale values can also be measured as percentages of black ink coverage - indicating 0% White E 100% Black.
You can also convert color artwork to high-quality black-and-white artwork through Grayscale. All color informati that is contained in the original artwork is discarded; where the gray levels (shades) of the converted objeo represent the luminosity of the original objects.
You can convert Grayscale objects to RGB and CMYK also.
