Applying the program for analysing the colours COLORMASTER to the examination of colours on leather samples EUROMODE 2000 made possible for us to realise certain ovine leather samples for gloved background dyed with a very small tolerance in comparison with the standard (3.84%). 4. Applying the COLORMASTER program to the analysis of the colour EUROMODE 2000 - INDIAN considered as Standard has allowed for the realisation of a bovine bleached crust leather finished with finishing solutions based on acrylic binders and pigment pastes White and Blue BISON almost identical with the Standard.
