Recently in the shop, it's been all about the silver ink on black paper! After experimenting with various colors of ink, the silver wins out every time. The silver ink yields the sharpest results... hands down. Silver is considered to be the most opaque color available. Opaque white inks pale in comparison to the luminosity of silver ink. White ink never prints purely white; it comes out more of a muddy gray than anything else. So instead, we highly recommend using silver. Have a looky-loo for yourself.
