Consider the following statements about grey component replacement.
1. It substitutes black for the grey component of three inks.
2. It reduces ink use and improves registration tolerance.
3. It always improves the appearance of dark saturated colours.

  • A.All of them
  • B.1 and 2 only
  • C.3 only
  • D.1 only

Answer: B

Correct answer: 1 and 2 only

Statements 1 and 2 describe grey component replacement correctly. Statement 3 claims too much: replacing chromatic ink with black can flatten the darkest saturated colours, since black contributes no chroma. This is why the amount of replacement is a setting to be judged rather than a switch to be turned fully on.
