Black business cards are a favourite across the design and marketing worlds — there is something genuinely magnetic about the colour black, and it carries a real sense of mystery. On press, though, a black base is far from easy to work with, and getting any other colour to sit on top of it takes some know-how. In this article we break down exactly how we print white — and other colours — onto a black card.
What is white-ink printing?
In ordinary four-colour (CMYK) printing, white is not laid down as ink at all — it is simply the colour of the paper showing through. The whiter your stock, the whiter your "white" looks. That is also why CMYK alone can never produce white on a coloured card: there is no white paper to reveal. To get white onto coloured stock, you need actual white ink, applied as a dedicated white-ink pass. One thing to keep in mind: white ink is easily influenced by the colour of the card underneath it. Print it on a black card and the result comes out as a greyish, off-white rather than a pure white.
Printing white and colour on a black card
Because black is a blend of many colours, printing most colours straight onto a black card barely registers — the dark base swallows almost everything you put on it. So to print in colour on black stock, we lay down white first, then the colour on top. That white pass lets the black card mimic a white-paper base, and any colours printed over it show up far more cleanly.
Bear in mind that white ink cannot completely mask the black underneath, so colours on a black card come out more muted — never as vivid as the same artwork printed on white paper.
Beyond white ink: white foil stamping
Because white ink cannot achieve a truly bright white, foil stamping makes a great alternative — here we use a white metallic foil. Stamping white foil works a little like correction tape, covering the black directly, so unlike white ink it is not tinted by the card's colour.
White foil does not suit every design, though. Very intricate patterns and fine text do not stamp well — lines that sit too close together or run too thin tend to smudge into one another, so the text or artwork will not read clearly. For anything really detailed, we would suggest printing rather than foiling.
Not keen on white ink or foil? There is a third option
If neither white ink nor white foil gives you the look you are after, you can flip the approach: start with a white card and flood it with a full bleed of black. Because a solid black lays down a heavier layer of ink, the finished card takes on a glossy, lacquered sheen — and the "white" in your design is simply the natural white of the paper showing through.
If you love a natural paper feel, printing black onto a white card may be the better fit — just note that the card edges can rub and lose a little colour over time.
