How halftone printing works

Before digital screens, printers reproduced photographs by photographing them through a fine mesh screen to break continuous tones into dots. Large dots cover more paper and appear dark; tiny dots leave more white and appear light.

Digital halftone art

Today halftone effects are popular in poster design, comic-book style artwork, retro branding, and t-shirt printing. Adjusting dot size and contrast lets you range from subtle texture overlays to bold graphic prints.

Print resolution: LPI guide

Print type	Lines per inch (LPI)	Notes
Newspaper	~85 LPI	Coarse; visible dots on newsprint
Standard magazine	133–150 LPI	Common offset lithography
High-quality magazine	150–175 LPI	Glossy paper, fine detail
Fine art / art book	175–200+ LPI	Near-photographic quality
Screen printing	45–65 LPI	Coarser due to mesh; varies by mesh count

CMYK screen angles

In four-color offset printing, each ink color's halftone screen is rotated to a different angle to prevent the dots from aligning and creating a distracting interference pattern called moiré. Traditional angles: Cyan 15°, Magenta 75°, Yellow 0° (least visible), Black (Key) 45° (most prominent). Modern stochastic (FM) screening uses randomly placed dots of uniform size instead, eliminating moiré entirely.

Pop art and halftones

Roy Lichtenstein's paintings (1960s) replicated the Ben-Day dot process used in cheap comic book printing - hand-painted dots that mimicked the mechanical halftone screens of mass-market print. By reproducing these dots at large scale in fine art, Lichtenstein elevated the industrial printing artifact into an artistic statement about mass media and popular culture.

Frequently asked questions

What is halftone printing?

Halftone is a reprographic technique that simulates continuous tone by varying the size and spacing of dots. In traditional printing, dark areas are covered by large dots and light areas by small ones, creating the illusion of tonal gradation using only one ink color.

Can I use a custom foreground and background color?

Yes. The tool lets you set both the dot color (foreground) and the paper color (background) independently.
