What is the purpose of trapping width settings in prepress?

• A. To define the amount of overlap between colors and prevent gaps due to misregistration.
• B. To set the page margins.
• C. To control paper stock texture.
• D. To determine the duotone conversion.

Answer: (A)

Trapping width settings in prepress focus on creating a deliberate overlap between adjacent color areas so there’s no visible gap if colors don’t line up perfectly during printing. By adding a small amount of overlap, the traps compensate for misregistration, press movement, and dot gain, ensuring clean, seamless color edges even when the inks don’t register exactly. The other options don’t address this edge-to-edge reliability: trapping isn’t about setting page margins, altering paper texture, or converting to duotones.
