What is the effect on printed image quality of increasing the DPI (dots per inch)?

• A. Higher DPI increases resolution
• B. Higher DPI decreases resolution
• C. DPI has no effect on image quality
• D. Higher DPI reduces color fidelity

Answer: (A)

Increasing printing DPI means more ink dots per inch, which allows the printer to sample and reproduce finer detail. DPI measures how densely the printer can place dots; higher DPI yields sharper lines, smoother edges, and more accurate texture, so the printed image quality improves as DPI goes up—assuming the original image has enough detail to support that higher sampling and the printer can render that many dots. If the source image doesn’t contain enough information, cranking up DPI won’t add real detail and may not improve quality. DPI isn’t about reducing color fidelity; color accuracy depends more on color management and inks, while DPI mainly affects the level of detail in the print.
