Overprint describes printing one layer on top of another. What issues can occur if overprint is misconfigured?

• A. Overprint is the process of printing a background color only.
• B. Overprint is used to hide underneath inks.
• C. Overprint refers to reducing ink usage.
• D. Overprint prints one layer on top of another; misconfigured overprint can cause color buildup, misregistration, or blocking.

Answer: (D)

Overprint means printing one color on top of another instead of knocking out the underlying color. When this setup is off, you can see color buildup, misregistration, or blocking. Color buildup happens when the top layer adds ink exactly where the bottom layer already sits, making that area darker or off in tone. Misregistration is when the ink layers aren’t aligned precisely, so edges don’t line up and you get blurred details or a doubled look. Blocking occurs with wet, stacked inks that stick together or transfer to the opposite side, which can cause sticking or poor drying, especially on damp or absorbent stock. Those other descriptions aren’t accurate because overprint isn’t limited to a background color, isn’t primarily about hiding inks, and isn’t defined by reducing ink usage. The real concerns with misconfigured overprint are unintended color buildup, misalignment, and blocking.
