Mirror gold is a metallic effect ink, and prints well up to 62T, but we'd suggest a 55T. If you try and print higher than 77T, the fine mesh will literally sheer the metallic pigment out of the ink, which will progressively become more problematic on longer print runs as the metallic bits build up in the screen.

Over six months to a year of wear, union metallic inks will gradually loose their metallic sheen and flatten to solid colours.

But they look pretty incredible printed!
