Which measure relates to halftone printing and controls line density?

• A. Pixels per inch
• B. Dots per inch
• C. Lines per inch
• D. Color depth

Answer: (C)

Halftone printing uses a grid of dots to create tones, so the important measure is how many lines of that grid fit in one inch. This line density is called lines per inch. It directly controls how fine the halftone pattern is: more lines per inch means smaller dots and a smoother tonal range, while fewer lines per inch produces a chunkier, more visible dot pattern. Pixels per inch and dots per inch refer to resolution or dot count in digital or printed images, not the physical line density of the halftone screen. Color depth is about how many color levels the image can store per pixel, not about the halftone screen density. So lines per inch is the correct concept for halftone line density.
