What is a duotone?

A duotone is an image printed with two inks, most often black plus one spot color, to add tonal depth or a stylized tint. It gives more richness than plain grayscale while using fewer inks than full-color process printing.

• Blends two inks across the tonal range for added depth.
• Common combination is black plus a single brand or accent color.
• Delivers a distinctive, on-brand look for photos and backgrounds.
• Uses fewer inks than CMYK, which can suit two-color designs.
