Colour and colour change testing

We perform colour and colour change measurements using spectrophotometers. Measurements are made at standard measurement geometries: 45/0, d / 8, d / 0 for various types of reflecting, transmitting and light-scattering materials, as well as fluorescent materials.

Test objects

  • plastics,
  • paint layers,
  • reflective films,
  • safety clothing,
  • glass.

Testing range

  • material colour measurements (results in the form of coordinates: xy, CIEXYZ, CIELAB, CIELUV, etc.),
  • change in colour following aging and light resistance tests
  • spectral reflection coefficient, transmission of light,
  • spectral plots (spectral reflection coefficients, transmission),
  • measurements of wide-angle spread (haze).

Devices

  • X-Rite Color i5 spectrophotometer,
  • X-Rite CF57/CA spectrophotometer.
