The main reason CIEDE2000 has not entirely displaced CMC in textiles is

  • A.that CIEDE2000 requires spectral rather than tristimulus data
  • B.the weight of existing tolerance data expressed in CMC
  • C.that CIEDE2000 cannot be computed by modern instruments
  • D.that CMC is more accurate for every kind of sample

Answer: B

Every stored tolerance would need re-establishing against visual judgements. The cost of that exercise outweighs the modest gain in accuracy. Every stored tolerance would need re-establishing. The cost outweighs the modest gain.
