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