Assertion (A): Grey component replacement improves the stability of a print run.
Reason (R): Replacing three overlapping inks with black reduces sensitivity to registration error.

  • A.Both A and R are true, and R is the correct explanation of A
  • B.Both A and R are true, but R is not the correct explanation of A
  • C.A is true but R is false
  • D.A is false but R is true

Answer: A

Correct answer: Both A and R are true, and R is the correct explanation of A

Both are true and the reason gives the mechanism. Where cyan, magenta and yellow would all be laid down, the common grey component is replaced by black. Three overlapping inks become one, so a small misregistration no longer shifts the colour, and the total ink laid on the sheet falls with it.
