Notes

Use binders with a low degree of acidity (neutral) to improve the stability of the ink.
Aggressive binders (i.e. nitrocellulose) can provoke a reaction of the metallic pigment in the binder.
When using aggressive binders, keep the quantity of binder to a minimum and increase the solvent loading.
Using a high rotation mixer may break the particles and as a result lower the shine and metallic effect.
