What is Halftone Printing?
Halftone is the printing technique that lets you reproduce a photograph using only one ink. It's the dot pattern you see on every newspaper, every Lichtenstein painting, every screen-printed t-shirt.
How it works
Printing presses can only put ink down or leave the paper blank — they can't print "50% gray." So how do you reproduce a photograph with gradients?
You break the image into a regular grid of dots, then vary the size of each dot. Big dots in dark areas, tiny dots in light areas. Your eye blends the dots together at normal reading distance and sees a smooth gradient.
Look at any newspaper photo up close — that dot pattern is halftone.
A short history
The technique was patented in the 1880s. Frederic Ives in Philadelphia and others developed it independently to solve the same problem: how to print photographs alongside text using the same press.
Before halftone, newspapers could only print engravings — hand-drawn versions of photos. Halftone made the actual photograph reproducible, which transformed journalism, advertising and book publishing.
Where you still see halftone today
- Newspapers and magazines — still the standard for photo reproduction.
- Screen printing — for t-shirts, posters and packaging. Limited inks force halftone tonal tricks.
- Comics — Roy Lichtenstein famously exaggerated halftone dots in his pop art.
- Risograph — each ink layer is halftoned before being printed.
- Editorial design — designers add halftone as a deliberate retro effect.
Halftone patterns
The classic halftone is a grid of circular dots, often rotated 45° so the grid is less visible. But you can use other shapes:
- Circular dots — the standard, smooth look.
- Line screen — variable-width horizontal or angled lines. Common in old maps.
- Diamond — rotated squares, slightly sharper than circles.
- Cross hatch — overlapping lines, more illustrative.
- Square grid — pixel-like, modern and digital.

Halftone vs dithering
People often confuse halftone with dithering. They look similar but they're different:
- Halftone: variable dot size, fixed grid.
- Dithering: fixed pixel size, scattered or patterned placement.
