COLOUR FASTNESS

This type of test is basically based on the analysis of colour decay. In particular, we test the stability and brightness of colours in order to ensure that the product will not be subject to undesired chromatic variations due to rain or intensive use. 

These tests consist of chemical tests used to ascertain the stability of the colour when in contact with:



    

  • UV RAY
    • 

  • RUBBING
    • 

  • WATER
    • 

  • SWEAT
    •
