Print resolution measures how many dots or pixels fit in a unit of length.
Key terms:
- DPI (dots per inch) — printer output resolution
- PPI (pixels per inch) — screen/image resolution
- DPCM (dots per cm) — metric equivalent
- LPI (lines per inch) — halftone screen frequency
Conversions:
- 1 DPI = 0.3937 dots per cm (1 / 2.54)
- 1 dot per cm = 2.54 DPI
- LPI ≈ DPI / 2 (general rule for halftone printing)
