Metallic and Fluorescent Ink
Inks that cannot be built from CMYK, so they only exist as a separate pass.
What it does
Pantone 806 fluorescent pink and metallic silver 877 cannot be reproduced by process colour at all: the fluorescent re-emits ultraviolet as visible light and the metallic contains actual aluminium flake. That is exactly why they signal print. Metallic reflectivity changes with viewing angle, so a metallic solid is never one flat value. Fluorescents look wrong on screen because a monitor cannot exceed its own gamut, which is part of their appeal on paper.
