A strength factor applied to a colourant in the database

  • A.changes which observer functions are applied
  • B.converts the measured reflectance into K over S
  • C.scales its concentration to compensate for lot variation
  • D.changes the price used in the cost ranking

Answer: C

It is determined by dyeing the new lot and comparing against the stored data. Applying it avoids recalibrating the whole colourant from scratch. The factor is found by a single dyeing. Full recalibration is thereby avoided.
