SO-RIRISO printing, and publishing studio

SO-RI is a small RISO print studio, operating from our garage in Borgerhout, Antwerp.

We are both a print studio and a publishing house.

Which means we offer print services for all your designs, zines, posters, and more. And we also publish a select amount of artist editions and occasionally sell a limited edition RISO art print.

Print together

Let’s print together! It’s exactly what it sounds like. You’re invited to come and print with me. I guide you through the process of making a RISO print and we discuss what paper to print on.

This means it isn’t just a service where you drop off your files, and pick up your prints. But instead you’re involved all the way through the printing process, which means you know what happens when printing, and can witness the full print process.

Drop off your files, pick up your prints

While we prefer to print stuff together, it’s of course also possible to just send me your files, and pick up your prints later.

When it’s your first time RISO printing with SO-RI, we’ll ask you to print together with us so you become familiar with the printing process. You can of course still say “no” to that.

The pricing is the same as printing together.

Book an appointment

Book an appointment with me for printing, using the tool on this page. Or send me a message to see what’s possible.

Usually I am available on:
  • Monday from 10AM to 5.30PM,
  • Tuesday from 10AM to 5.30PM,
  • Friday from 10AM to 3PM.

We are not printing during (Belgian) school holidays. 

Are you printing a zine or a publication?
I would love to book a full day with you, so we can print it together. Send me a message to make an appointment.

Doubting about how much time you need to book in the Bookings tool?
  • 30 minutes is perfect for getting some information, and a small talk.
  • 1hr is perfect if you already have some experience with RISO printing and you have a rather small print assignment.
  • 2hrs is perfect for a larger print assignment if you have some experience with RISO printing, or a small print assignment if you don’t have any experience with RISO printing.

If you’d like to print on any other date or time, feel free to send me a message or mail me at sori.printstudio@gmail.com and we’ll see what we can do.

We can even go for an evening print session or a weekend print session, if that’s your only option.

How to use our calculator

* The start-up fee is a cost you pay once per printing session (whether you print one A3 design or one hundred, you only pay the start-up fee once per printing session), or once per zine in the case of printing a zine.

1 We have three different pricing brackets to choose from:
Discount is for art students. Social, and leftist progressive organisations and movements can apply for an extra discount.
Regular is for most people, and small local businesses.
Corporate is for corporate jobs, this includes big businesses, but also graphic designers charging their clients. Also in this pricing brackets are birth cards and alike.
Not sure about the bracket you are in? Send me a message or ask me in person before printing.

2 The difference between special and regular ink is noted in the “RISO printing” chapter on this page, special colours are denoted by the symbol, and currently are Fluor. Green, Violet and Aqua, while regular inks are denoted by the symbol.
We quite a bit more for special inks, which is why they are more expensive for you as well.

3 Bringing your own paper is free, as it saves me the hassle of stocking paper, buying paper, choosing paper, etc. And as an extra plus: you get your own choice of paper. Please make sure that the paper is uncoated and heavier than 70gsm, but lighter than 230gsm and isn’t prone to losing fibers, isn’t too smooth, nor too textured. 
Printing on your own paper is always at your own risk, and we can not guarantee that your paper will go through the machine perfectly, nor that your paper is perfectly compatible with RISO ink.

4 The page size refers to the size of a single page. It doesn’t refer to the spread size or the plate size. Please keep in mind that the RISO doesn’t print up to the border, so a full A4 sized zine won’t work. Give your pages a bit off space on the sides.
If your page size is smaller than A4, but larger than A5, always go for the bigger size in the calculator.

5 The number of pages should be: 
a multiple of 4 if you’re printing A4, 
a multiple of 8 if you’re printing A5 or 
a multiple of 16 if you’re printing A6. 
The number of pages doesn’t include the cover.
It’s impossible to print a regular zine that isn’t a multiple of 4 pages, use the numbers above to optimize your usage of the A3 sized paper.

6 The minimum amount of copies is always 20. You can print less, but you will always pay for at least 20 copies. This is because making the Master, making sure the ink spreads well, etc. takes time, ink and paper. The RISO is made for multiples, please keep this in mind and minimize waste.

What is RISO?

RISO is a Japanese brand of duplicators and printers. When people talk about risographs, they usually refer to the duplicator series of printers. They are quick, easy and cheap to print from and perfect for mass printing.

Origins

The RISO machine itself looks kind of dull, almost like a big old copier. And that is, because in some ways, it is.

The RISO technology is actually a digital stencil machine. Stencil duplicators were the predecessor to modern copy machines.

The RISO was originally used in office environments, schools, churches, sporting clubs and political parties to quickly print multiple copies. Whether those were announcements, letters, pamphlets, or posters, the RISO did it all fast and at a low cost.

Later on, it was picked up by artists and creatives to print zines. To whom it was attractive due to its low cost and lo-fi charm and analogue look.

Eco-friendly

The ink in the RISO machine is made from the byproducts of rice farming. The machine itself doesn’t have a heating element to dry the ink, which makes it more energy efficient.

Both of these aspects make the RISO technique a rather eco-friendly option for your print work.

Multiples

Because of the stencil-based nature of the RISO printing process, it is well suited to print multiples of the same print.

The cost of the Master sheets would not really make sense to print a single copy of anything.

SO-RI suggests printing posters, flyers, zines and artist editions for the RISO technique to be an affordable and charming way to present your work or advertise your company, organisation or event.

Imperfections

RISO printing is known for its lo-fi charm, so be sure to expect a lot of small and large imperfections. Registration marks will not consistently line up. Smudge marks from handling the paper quite often appear. Roller marks from the machine and ink residue from other inked paper might be visible. Most smudges and ink spots can simply be rubbed away with a rubber gum, just make sure not to rub over any inked areas. Try to avoid large inked areas in your design to avoid a lot of smudges.

If you’re not willing to deal with imperfections, smudges and misalignments, RISO printing might not be the thing for you.

Colours

SO-RI has 18 colours to choose from. Please note that these are not your typical CMYK colours and that RISO requires a completely different mindset to work with.

To figure out the workflow of prepping your files for graphical work, illustrations or photography, check out the “file prep” chapter on this page.

Hex codes

Use these hex codes in your favourite software to approximate the RISO ink colours. Don’t forget that screens can’t reproduce all colours accurately.

Colour drums

To print a colour, you need an ink drum. Each colour is stored in its own drum, which is a piece of hardware, which holds an ink tube, a master stencil and eventually imprints an image onto your paper.

Because each drum holds only one colour, and our machine prints with only two drums at a time, printing more than two colours requires you to change out the drums and send the paper through the machine multiple times.

Because the master stencil is stuck to the drum, each additional colour will require a freshly burned stencil.

Which paper can you use?

You can always bring your own paper stocks to me and check if it prints. There’s no guarantee that it will work and bringing your own paper is always at your own risk.

Most papers work that are:
  • uncoated
  • not too textured and not too smooth
  • preferably between 90gsm and 210gsm, sometimes you can be lucky between 70gsm and 230gsm

Papers in our stock

While we are always open for suggestions we try to stock several types of paper. Not all paper types on our website are always in stock, feel free to ask us about what we have in stock right now.

You may find scans of some of our papers down below.

[coming soon]

Currently we are not stocking many different types of paper, but our paper offerings will be expanded in Q2 2025, after our studio has undergone its final renovations.

Preparing your files

Before we start off: remember I am here to help you. Especially in your first couple of times printing with the RISO I will explain everything in detail. Don’t worry about asking too much questions, I am more than happy to help. I will assist you in preparing your files, explain everything in detail and I will even give advise on your choice of inks.

Some basics

Let’s start off with some basics. Remember that the machine:

 prints one colour layer at a time.

 works with 1 black and white file per colour layer (where darker leads to a more intense colour). You can work with gradients and greyscales within this file.

 the inks are semi-translucent, this means that if you print one over the other they will start to mix instead of cover each other. This gives you way more colour options by mixing, but if you want pure colours, make sure there’s no other colour underneath.

File types

I accept a variety of file types. You can deliver me:

  • clearly labeled black and white layers in 1 PSD file

  • clearly named JPG, PNG or TIFF files

  • clearly labeled PDF files (if each page is a different colour layer, please mention it clearly in the file name and in your e-mail).

  • please note the name of the colour you would like to use into the filename. Please use the same name for the colour as we do on the website.

  • InDesign packages, if you’re working on a zine.

  • convert your layers into black and white. I prefer working with files in RGB. While it seems counter-intuitive, the workflow I am following usually gives the best results when you work in RGB, so please make sure your images are not in Greyscale, nor in CMYK.

  • the RISO I am working with allegedly goes up to a resolution of 600dpi. For the best quality please make sure your files are set up for at least 300ppi in your preferred printing size.

  • I do not work with unlabeled files, nor with Illustrator files.


Size

Make sure your files are sized properly. The machine always prints on A3 sized paper using an A3 sized master.

So if you want to print an A5 size card, don’t waste paper and fit several on 1 sheet of A3 paper.

If you want to print a 25x35cm print, place it on an A3 sized canvas.

For zines, just make sure your page size is as you want it to be.

Example

Down here you can find a wonderfully beautiful example of Juliane Noll’s Sunset print.

The black and white images are what we sent to the RISO, the colour layers are the separate ink layers the RISO gave us.

The fourth image is all the inks combined into one image. Take note of how the colours mix when they overlap.


Graphic design & digital illustrations

For graphic design and digital illustrations it’s best to start off your design using seperate colour layers and converting them to black and white.

You could also work with black and white layers and in Photoshop use a solid colour adjustment layer on the screen blend mode and each black and white layer on a multiply blend mode. This gives you a pretty clear preview of what to expect from the print (remember screens can’t properly show fluorescent colours).

Analog illustrations, paintings and photographs

RISO works perfectly for monochromatic images. Whether those are black and white photos, or illustrations, they will work fine. Just send me your black and white images and tell me which colour of ink to use. 

Sometimes you just can’t start off designing your illustrative work in seperate black and white layers. The same counts for colour photographs.

This is not a problem. Just use the Spectrolite app, it’s free, and designed for Mac OSx. And you can find it here: link

It makes seperating colours easy and intuitive.

[Thanks Anemone, Adam and Amelia, for developing this app!]
