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.
