What Is a Halftone Pattern?

Halftone is a printing technique that reproduces images using dots of varying sizes. Larger dots represent darker areas, while smaller dots represent lighter areas. This technique has been used in newspapers, comic books, and screen printing for over a century.

The Halftone Pattern Generator lets you convert any image into a halftone dot pattern with full control over dot shape, size, spacing, angle, and color. Whether you're going for a vintage newspaper look, a bold pop art style, or an authentic CMYK print separation, this tool gives you creative control over every aspect of the effect.

How to Use the Generator

Load an Image

Upload your own image by clicking the upload area or dragging and dropping a file. You can also click one of the sample images (Portrait, Landscape, Object) to try the tool instantly.

Choose a Preset or Customize

Select a preset style for a quick start, or customize every parameter manually: dot shape, size, spacing, angle, colors, contrast, and brightness.

Newspaper

Small, tightly-spaced black dots for classic print look

Comic Book

Larger dots with high contrast for bold illustrations

Pop Art

Bold pink dots with a retro 60s feel

Vintage

Warm brown tones for an aged, nostalgic look

Risograph

Fine blue dots mimicking riso printing technique

Fine-Tune the Settings

Adjust the dot settings in the left panel. Choose from 6 dot shapes (circle, square, diamond, line, cross, hexagon), set the dot size and spacing, and rotate the pattern angle. Switch between Black & White, Single Color, or CMYK color modes.

Download Your Result

Click Download to save your halftone image as PNG, JPG, or SVG. SVG output produces scalable vector graphics — ideal for print projects that require high resolution at any size.

Features

6 Dot Shapes

Choose from Circle, Square, Diamond, Line, Cross, and Hexagon shapes. Each shape creates a distinct visual effect — circles for classic halftone, lines for engraving-style patterns, and hexagons for a modern geometric look.

Circle

Traditional halftone, closely mimics printed photos

Square

Creates a pixel-art feel with geometric precision

Diamond

Adds a dynamic angle to your pattern

Line

Resembles engraving and cross-hatching techniques

Cross

Modern geometric alternative with unique texture

Hexagon

Contemporary geometric look with organic feel

Full Parameter Control

Fine-tune every aspect of your halftone pattern with precision controls:

Dot Size (2–30px) — Controls the maximum size of dots
Spacing (4–40px) — Distance between dot centers
Angle (0–180°) — Rotation of the dot grid pattern
Contrast and Brightness — Adjust the source image before halftoning
Invert — Reverse which areas get larger dots

Pro Tip: Smaller dots (2–6px) with tight spacing create detailed, newspaper-like results. Larger dots (10–20px) with wider spacing produce bold, graphic pop art effects. Use the presets as starting points and adjust from there.

3 Color Modes

Black & White

Classic monochrome halftone for timeless newspaper and vintage effects

Single Color

Choose any custom dot color for branded or artistic designs

CMYK

Full 4-channel color separation with standard print angles (C: 15°, M: 75°, Y: 0°, K: 45°) to minimize moiré patterns

Toggle individual channels on/off
Professional print-ready output
Authentic offset printing simulation

Multiple Export Formats

Raster Formats

PNG & JPG

PNG — Lossless raster with transparency support
JPG — Compressed raster for smaller file sizes
Best for web and digital use
Fixed resolution

Vector Format

SVG

Scalable vector output
Each dot is a vector element
Perfect for print at any resolution
Infinite scalability without quality loss

Why SVG? SVG (Scalable Vector Graphics) stores each dot as a vector shape rather than pixels. This means you can scale the image to any size without losing quality — ideal for large format printing, posters, and professional design work.

Frequently Asked Questions

What is halftone used for?

Halftone is widely used in printing, graphic design, and art. It's the technique behind newspaper photos, comic book shading, pop art, screen printing, and risograph printing. It creates the illusion of continuous tone using only dots of a single color.

What's the difference between the dot shapes?

Each shape produces a different visual style. Circles are the most traditional and closely mimic printed halftone. Squares create a pixel-art feel. Diamonds add a dynamic angle. Lines resemble engraving. Crosses and hexagons offer modern geometric alternatives.

What is CMYK mode?

CMYK mode separates your image into four color channels — Cyan, Magenta, Yellow, and Key (Black) — each rendered at a different angle to avoid moiré interference patterns. This mimics how full-color images are printed using halftone screens in professional printing.

Channel	Color	Angle	Purpose
C	Cyan	15°	Blue tones
M	Magenta	75°	Red tones
Y	Yellow	0°	Yellow tones
K	Black	45°	Depth & contrast

Why should I export as SVG?

SVG (Scalable Vector Graphics) stores each dot as a vector shape rather than pixels. This means you can scale the image to any size without losing quality — ideal for large format printing, posters, and professional design work.

What dot size and spacing should I use?

It depends on your desired effect. Here are recommended settings for different styles:

Style	Dot Size	Spacing	Effect
Newspaper	2–6px	4–8px	Detailed, fine print
Comic Book	8–12px	10–16px	Bold, readable shading
Pop Art	10–20px	12–24px	Graphic, eye-catching
Poster	15–30px	20–40px	Large format, bold impact

Use the presets as starting points and adjust from there based on your specific needs.
