Halftone vs Dither — What's the Difference?
Both halftone and dithering convert continuous-tone images into limited-color patterns. They look similar at a glance, but they solve different problems and come from different worlds.
The short answer
Halftone uses variably sized dots on a regular grid. Bigger dots in dark areas, smaller dots in light areas. It was invented in the 1880s to let newspapers reproduce photographs with a single ink color.
Dithering uses fixed-size pixels arranged in patterns (either error-diffusion or ordered). It was invented in the 1970s to let early computers display many shades using a tiny palette.
Side-by-side comparison
| Halftone | Dither | |
|---|---|---|
| Origin | Print, 1880s | Computer graphics, 1970s |
| Dot size | Variable | Fixed |
| Grid | Regular grid, often rotated 45° | Pixel grid |
| Used for | Newspapers, magazines, posters | Retro games, pixel art, e-ink displays |
| Best at | Smooth gradients in a single ink | Limited palettes, low-bit aesthetic |
| Look | Print, vintage, mechanical | Retro, digital, 8-bit |
When to use halftone
- You want a print aesthetic — newspaper, comic, screen-printed look.
- You're preparing artwork for actual one-color printing (screen, riso, offset).
- You want smooth tonal transitions in a single color.
- You like the visible mechanical grid of the dots.

When to use dithering
- You want a retro digital aesthetic — 1980s Mac, Game Boy, early Windows.
- You're working with a limited color palette (2, 4, 16 colors).
- You want crisp pixel-level texture rather than smooth dots.
- You're building game art, e-ink graphics, or pixel illustrations.

Can you combine them?
Yes — and it often looks great. A common workflow:
- Apply halftone to get the print-like dot grid.
- Export and re-import into the dither tool to add pixel texture on top.
- Optionally finish with ink bleed for an organic, hand-printed feel.
Common confusion
People often call any black-and-white pixelated image "dithered" when it's actually halftone, or vice versa. The shorthand:
- If the dots get bigger and smaller in size → it's halftone.
- If every dot is the same size, but more or fewer of them are placed → it's dithering.
