Blue wool scale (DIN 16525)

Analyzing printing inks and prints in Graphic Industries and basically tests and classifies the light stability of the below mentioned two categories: 

a.) Prints made on any printing surface with any printing method, independently from any specific condition,

b.) Test prints made with ink, strictly complying with the specifications defined in DIN 16519

Standards and Accreditation, The lightfastness of printed ink films is expressed by the change in their colorimetric appearance compared to standard blue wool samples. There are many international standards applied to the light fastness test including ISO 105-B01, ISO 105-B02, BS EN 20105-B02, BS EN 4892-2, BS ISO 2837:1996, BS ISO 12040:1997, BS ISO 2836:1999 and BS ISO 2834:1999 (Smithers Pira, 2017; British Standards Institution, 1997). DIN 16519, AFNOR Q64-022, DIN 16525 and ISO 2835 standards are detailed methods for printing test samples and measuring lightfastness (Brancher, 2017). The standard specification is DIN 16525.
