About the halftone dots screen

The round dot is the classic halftone: dots grow from tiny specks in the highlights to touching circles around 78% and fill solid in the shadows. Round dots hide misregistration well and are the default for print, screen printing and comic art.

0 → 100% — dot halftone example0 → 100%
Halftone dots on a 0–100% grey ramp: coverage tracks the tone exactly.

Round dots touch at about 78% coverage, which can cause a visible tone jump in dark midtones on press. If you see it, try the diamond shape, whose corners join at 50%.

Coverage is measured on the real screen, so a 40% grey becomes dots that cover exactly 40% of each cell — overlapping dots in the shadows are accounted for.

How to make a halftone

  1. Add an image. Click Upload image, drag a file onto the preview or paste with Ctrl/⌘+V. Photos, logos and gradients all work; transparent PNGs keep their transparency.
  2. Choose shape and size. Pick dot, line, square, diamond or cross, then set the cell size (dot spacing) and screen angle — or switch to CMYK for four color separations.
  3. Tune the tones. Open Tone to adjust contrast, dot gain and the minimum and maximum printable dot for screen printing, DTF or engraving.
  4. Download. Choose the output width and click Download PNG, or SVG for vector dots. Tick Transparent background to export only the ink.

FAQ

How do I make a halftone dots effect?

Upload an image, the shape is already set to dot. Adjust cell size and angle, then download a PNG or SVG.

Can I export halftone dots as SVG?

Yes. Every mark is exported as a vector path you can scale, recolor or cut.

What cell size should I use?

Cell size is the distance between dots in pixels. At 300 DPI output, cell size = 300 ÷ LPI: 6–7 px is about 45–50 LPI (screen printing on 230 mesh), 10 px is 30 LPI, and 16 px and up gives a bold pop-art look.
