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.

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:

  1. Start with a full-color photo.
  2. Split into two or three spot colors (e.g. Fluorescent Pink + Federal Blue).
  3. Apply halftone to each layer separately so the Risograph can print them as solid ink dots.
  4. 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.
