I am creating a colorant database for my matching software. How do I reduce the bronzing of Pth Blue at high concentrations?
The usual cause of this is that you have reached too high a concentration of colorant for your substrate and it is coming to the surface. Since this is happening, you are perhaps trying to construct your database at levels of concentration that will not be usable in your final products. You might well be able to build a usable database without going to such high concentrations.
