Riso vs Halftone — What's the Difference?
They're often used together, so it's easy to confuse them. But risograph and halftone solve very different problems. One is a printing process. The other is a screen pattern. Here's how to tell them apart — and how to use both.
The short answer
Halftone is a screen pattern — a way of reproducing continuous tones with a single ink by varying dot sizes. It can be applied to any printing process, or simulated digitally.
Risograph is a printing process — a duplicator from the 1980s that prints one spot color at a time using soy-based inks. To print photos on a Risograph, you have to convert them to halftones first.
So: halftone is what you apply, riso is what you print on.
Side-by-side comparison
| Halftone | Risograph | |
|---|---|---|
| Type | Image processing technique | Physical printing process |
| Origin | 1880s, Newspaper print | 1980s, Japan (Riso Kagaku) |
| Color | Any color, often single ink | One spot ink per pass (~70 colors available) |
| Look | Visible dot grid, mechanical | Bright, slightly grainy, misregistered |
| Used for | Comics, posters, screen prep | Zines, posters, art prints |
| Cost | Free (digital effect) | ~€0.10 per A4 per color, cheap at volume |
| Quality | As sharp as your output device | Charmingly imperfect — misregistration is part of the look |
When to use halftone
- You want a screen-printed or comic-book look in a digital export.
- You're preparing artwork for any one-color print process (including riso).
- You want full control over dot shape, angle and frequency.
- You're not actually printing — just want the aesthetic.

When to use risograph (the effect)
- You want the bright, slightly-off-register zine aesthetic.
- You're prepping actual riso prints and want a preview.
- You like soft grain, neon spot colors, and the "two-layer overlap" feel.
- You're designing for cheap, beautiful, small-run print.

Using them together (the pro move)
If you're actually printing on a Risograph, you'll almost always halftone first. Here's the typical zine-design workflow:
- Start with a full-color photo.
- Split into two or three spot colors (e.g. Fluorescent Pink + Federal Blue).
- Apply halftone to each layer separately so the Risograph can print them as solid ink dots.
- Print one color per pass — the misregistration adds character.
Our Risograph tool simulates this whole stack — choose your inks, the halftone gets applied automatically, and you can preview the final look before you commit to print.
Common questions
Can I export halftone artwork for Risograph printing?
Yes. Halftone Pro exports SVG vector files at full resolution — perfect for sending to a Risograph printer. Each color layer goes on its own page.
Do I need both tools?
It depends on your goal. Just want the look digitally? Pick one. Prepping for actual print on a Risograph? Halftone the source, then use the riso preview to check the spot colors.
Which has better print quality?
Halftone is exact and mechanical — what you see is what you get. Riso is intentionally imperfect: each pull is slightly different. That's the charm, not a bug.
