Which color option should I choose?
Full-color printing provides the maximum impact and visual appeal for most printing projects. However, if your budget is tight, a well-conceived two-color or even one-color design can prove an acceptable alternative.
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.
