White Ink can be printed on coloured stock, such as Kraft Brown board. The White Ink is typically printed first, before CMYK is over-printed on top. Coloured stocks will tint CMYK colours, unless a base layer of White Ink is printed first.
“White” – Swatch name for White Ink. Create a spot colour swatch, using a colour other than white, to identify it on screen against the white background.
White Ink should be placed on it’s own artwork layer, typically at the bottom.
CMYK objects should be set to “Overprint”, when printed on top of White Ink.
