Which colour option should I choose?
Most postcards are printed full-colour on both sides, particularly those that include colour images. If your postcards don't contain colour images or only have them on one side, you might consider a different option instead.
Two-colour printing, as its name implies, uses two ink colours. One is typically black, but it doesn't have to be. One-colour printing uses just a single colour of ink. Again, black is most common, but you can choose a different colour if you prefer.
Full-colour printing provides the maximum impact and visual appeal for most postcards. However, if your budget is tight, a well-conceived two-colour or even one-colour design can prove an acceptable alternative.
