What is trapping in color reproduction?

• A. Deliberate gaps between adjacent colors to prevent misregistration.
• B. Deliberate slight overlap of adjacent colors to prevent gaps due to misregistration.
• C. A technique to reduce color saturation.
• D. A method to convert RGB to CMYK.

Answer: (B)

Trapping is a printing practice used to prevent gaps where colors meet. When multiple inks are printed in layers, the color plates can shift slightly from perfect alignment. To compensate, printers deliberately extend one color into the neighboring color by a small amount, creating a tiny overlap at the boundaries. This keeps the edge from showing a white gap if registration is off and helps the overall image look smooth and continuous. It’s not about reducing saturation or converting color spaces; those are separate concerns. The overlap is kept very slight, just enough to cover potential misalignment, and the direction of the overlap can vary depending on the inks and design.
