DPI is a measurement used to describe the density of what in printing?

• A. Picas per Inch
• B. Dots per Inch
• C. Pixels per Inch
• D. Lines per Inch

Answer: (B)

DPI stands for dots per inch, and it describes how many individual ink or toner dots a printer can place in one inch of printed output. This dot density directly affects the perceived sharpness and detail of the image—the higher the DPI, the finer the detail and smoother gradients.

Papers what describes digital images, pixels per inch, which is about the density of pixels in a digital display or image, not the physical dots laid down by a printer. Lines per inch relates to halftone screening and the spacing of lines in a screen, not the actual printed dot density. Picas per inch isn’t a density measurement used for print at all—it’s a typography unit.

So the best match is dots per inch, as it explicitly measures the density of the actual printed dots.
