Unfortunately, Risograph production is rarely seen in many of the bigger commercial printing presses, most probably due to a scarcity of the machines within the UK, their initial start-up costs (anywhere between £200 and £3000 for the basic machine second hand, £80 for a master roll, £650 for one ink drum, £50 for one ink tube) and the time-consuming labour-of-love style of production. However, in recent years they have become hugely popular among artist communities, quickly rising to be a favoured method of producing both small and large scale runs of self-made publications, prints, and zines. There are now a multitude of specialist Riso studios within London and the UK, including Hato Press, Two Press, and Ditto. Most do not allow public access to their machines, and the one's that do operate on a send-to-print basis, meaning they take full control of the actual printing process.
Luckily, one of only a couple of publicly available Risograph machines can be found within Foundation Press, a small printing press run exclusively by the foundation students at the University of Sunderland, and the home of my former foundation course. After reaching out to the tutors there they were very keen for me to come back to Sunderland again and print my publication.
Book pages laid out in preparation for printing
The process of actually printing the book was more complicated than I had initially estimated. As always when using this particular machine, I knew to expect certain surprise elements. For example, the machine itself is relatively old as it was acquired second hand and has been in constant use at Foundation Press for nearly five years, and therefore is sometimes unexpectedly slow at performing certain tasks, or can break without any given warning whatsoever. What I had not anticipated was that a current foundation student at Sunderland had been using the machine the week before me and had had some issues with printing, which ultimately resulted in one of the drums leaking ink all over the inside of the machine. This required an internal service and although the machine was running again by the time I arrived, it was not running as smoothly as it should have been, and unfortunately meant that the red ink drum was out of action. I had planned to use a relatively large amount of red colour within my publication, and so I had to reconfigure the colour scheme of a large proportion of the book before printing any of the pages. Luckily the pink ink drum was still useable, and when used lightly or layered over yellow it could produce similar effects, although this would mean that the tone of the publication would be slightly altered, enhancing the naivety of its appearance.
After some necessary changes, printing the bulk of the publication went relatively smoothly. When printing full pages it is always important to leave an appropriate amount of time between different layers, as each page come out slightly damp and needs to be allowed to dry between runs through the machine. Running wet pages allows ink to build up on the internal rollers and can leave roller marks across your pages. Depending on how saturated the page is depends on how long it must dry for: large areas of 100% density can take up to twelve hours to dry properly, whereas lighter layers, such as small text or areas with a low density may only take 20-30 minutes.
I used a recycled office stock called Evercopy Plus at 80gsm, which is a relatively thin stock to use for this type of printing. Some of the more heavily printed areas showed through on the backs of the pages, which was something I had not initial accounted for, but I found that this worked in favour of the publication, as the translucency of the pages enhanced the feeling of tenderness portrayed through the illustrations, and allowed many of the designs to be seen almost as a sequence rather than individual prints.

As with any process involving inks it is also necessary to clean the machine before and in between large runs of paper. With constant use and a daily run or inky pages it is natural for ink deposits to build up on the internal mechanisms, so this should be done with isopropyl alcohol after about every 500 copies.
There are a myriad of other small problems that occur regularly when printing with a Risograph, including paper jamming and layers misaligning as they are printed, but many of these can be fixed easily and quickly using the controls on the machine. The machine accommodates for adjustments in incoming paper weights, ensuring that each page passes through and is printed without smudging or delay. Naturally when layers of colour need to be tightly aligned, there are often mistakes, but the Riso allows for printed images to be aligned correctly by adjusting the position of the ink drum inside the machine, allowing layers to be moved by 0.5mm, all the way up to 1cm. This extra added freedom of control ensures high quality outcomes and reduces paper waste.
Despite missing the red drum I was still able to print with five colours - blue, green, pink, yellow and black. Every page had multiple layers of ink, each of which requiring a different coloured drum and a new master, but as adjustments to the colours and the layout of the content were made throughout the printing process, the number of different drums and masters increased. As a result, some pages required up to four drum changes and six to eight masters per fully printed page.
Midway through the printing I was plagued with another large setback. The ink inside the blue drum began to run out, and although there was spare ink to replace it, it wasn't actually compatible with this particular machine. I was only able to produce one more run of pages before the drum refused to print any more. Printing was once again halted as I had to stop and rework my colour scheme yet again.
The five ink drums in their cases
Some issues, such as running out of ink, can be side-stepped and worked around. However, if something breaks internally and the mechanism stops running, there are only two companies in the UK that are on call to fix it. If they cannot be reached, or more likely you can't afford to hire their services, you have to roll up your sleeves and get the manual out. Risograph printing is a far more physically process than it first appears, but as a practicing creative this actually serves to be useful. Learning how the machine works physically (and how to fix it) allows for a deeper understanding of this particular printing process, and give foresight into how work can be tailored and created and to gain the absolute maximum from this machine, while also furthering the appreciation of physical vs. digital printing methods and how they can be used in conjunction with one another.
In total I printed a run of 35 copies for each page, with a margin of five pages to account for printing errors, leaving me with 30 editions of the publication. Although this is a relatively large number for this project, the nature of the machine requires that a minimum of 20 copies is printed per master to ensure that the ink is properly coated inside the drum, and it is more energy and ink efficient to produce larger volumes of prints.
Due to the obviously popular demand of this Risograph, the machine was only available to me for a brief three day window, but working for the maximum of the 21 hours that I was given meant that I was able to print the entirety of my publication within this time.
