All of the following improve right first time EXCEPT

  • A.using computer recipe prediction
  • B.increasing the size of every batch
  • C.standardising incoming dyes against a reference
  • D.controlling water hardness and alkalinity

Answer: B

Batch size has no bearing on whether a shade comes out right, though it does change the cost of getting it wrong. The other three are the three standard levers a dyehouse pulls. Larger batches simply lose more when they fail.
