Solution Number00000654
Solution Details
Background
Gray can be made out of a percentage of black, but it can also be made out of equal percentages of ink on each of the CMYK plates / RGB channels.
The Enfocus products offer checking on the use of 'impure' gray colors.

Solution
Impure gray is a tint of gray that is made out of different amounts of ink/light on the CMYK plates / RGB channels.

Here are some sample cases to help you understand what colors are seen as RGB gray.
RGB gray: the same % on each channel
R = 1%, G = 1% and B = 1% => This will be seen as RGB gray
R = 25%, G = 25% and B = 25% => This will be seen as RGB gray
R = 46%, G = 41% and B = 47% => This will not be seen as RGB gray

CMYK gray: same % on CMY, K = 0%

C = 40%, M = 40%, Y = 40% and K = 0% => This will be seen as CMYK gray
C = 10%, M = 10%, Y = 10% and K = 0% => This will be seen as CMYK gray
C = 30%, M = 20%, Y = 10% and K = 0% => This will not be seen as CMYK gray
C = 30%, M = 30%, Y = 30% and K = 80% => This will not be seen as CMYK gray
