Colour measurement in the textile industry is important as a means of  checking dye bath strengths to ensure continuity of colour within batches. Also as a means of checking  the colour of the waste water before and after treatment. 

Metamerism is another reason for colour measurement in the industry as dyes of different composition often create a mismatch under different lighting conditions and this problem can be forseen by examining test pieces before going into full production.

Scales & Values

Grading techniques are widely used to assess product colour by comparison with a representative series of fixed colour standards.

For many product types, a characteristic set of standards was agreed and adopted to aid colour control and the communication of colour specifications; the result is a selection of traditional colour grading scales that have been adopted as industry standards and are still in common use today.

Your Colour Scale requirement determines your instrument choice.
  • CIE 94
  • CIE L* u* v* Colour Space
  • CIE L*a*b
  • CIELAB (L*C*h)
  • CMC Tolerancing
  • Delta E* colour difference
  • Hunter Lab
  • Metamerism index
  • Spectral data
  • Whiteness Index (ASTM E 313)
  • xyY chromaticity co-ordinates
  • XYZ tristimulus values
  • Yellowness Index (ASTM E 313)
