Welcome to the Riso intro guide! A Risograph is a fantastic machine with a variety of options for creating exciting prints. This is a basic overview of how to properly utilize Riso to create new and unique looks for your work. Riso means ideal in Japanese. The Risograph was invented in 1986 by the Japanese company RISO Kagaku Corporation. You will be able to print up to two spot colors at a time. You can achieve similar print textures like you would with screen-printing but at a fraction of the time and cost. If you still have questions after reading this, please see one of the DIC staff members who will be able to assist you. Let’s get started! 4
Riso 101 What does a Riso Printer Do? The Riso Machine creates a ‘digital’ stamp’ of individual colors (which are incredibly vibrant!) and together they create a colorful image. How does a Riso Work? When you scan or upload an image to the machine, it first makes a paper stencil and wraps this around the ink drum - these are called masters. Paper is placed on the feeder and passed through one or two of the ink drums. Below are a few basic tips to get the best out of your designs for Risograph printing. We’ll look at setting up your files in Photoshop, turning your colors to grayscale, and then how to save them. 5

File Preparation 1. Create a new document in Photoshop. File menu > New document [Checklist] ○ Resolution: 600 dpi ○ Tabloid (11”x17”) or Letter size (8.5”x11”) ○ Portrait Oriented ○ Select color mode RGB 1. Make sure you allow a border around your design of at least 0.24 inches because Risograph printers can’t print in full bleed. Letter - Printable Area: 7” x 10“ Tabloid - Printable Area: 10” x 16“ 8
Color Separations Photoshop Spot Colors (Option 1) We are now going to learn how to prepare for designing in SPOT colors. If you set up your file this way you can see how the colors will come out while having your colors separated in your layers. 1. Label each layer. 2. Click New Fill or Adjustment Layer” & select Solid Color. The New Fill Color symbol is located in the Layers panel. 3. Select the Riso color you want from the Riso Swatches Panel. 4. Click Ok. 5. Select the Fill color layer name you just created in the Layers Panel. Click the Blending Mode menu and select Screen. 9
6. Right-click your mouse on the FIll Color layer, and select Create Clipping Path. 7. Select the standard layer and change the blending mode to Multiply. Understanding the New Fill Color and clipping mask. When you are ready to print, you print the grayscale layer to the Riso. The image mode is set to Multiply so you can see how your colors will look printed. The Fill Color and Clipping path are deactivated. Use the grayscale image to print to the Riso. Fill Color is active. Repeat this process for each color and layer. 10
From Channels to Layers (Option 2) Use this tutorial to prep your complex image (photograph) or flattened full color artwork for printing on the Riso. 1. Open your file in Photoshop. 2. In the Layers Panel, select the lock next to Background 3. Rename layer to “Original” 4. Image Mode > CMYK > Color 11
5. In the Layers Panel, select Channels. 6. Select Black 7. Select > All (⌘+ A) 8. Edit > Copy Merged (⌘+ Shift + C) 9. In the Layers panel create New Layer (⌘+ Shift + N) 10.Name new layer “Black” Edit > Paste (⌘+ V) 11.Click the layer Eye icon to make it invisible. IMPORTANT: Do NOT skip this step. 12
12.Repeat for Cyan, Yellow, and Magenta. You can do this in RGB mode by following these steps but changing your layers to Red, Blue & Green. 13
Riso Print Preview 1. In the Layers panel, Click “Create New Fill or Adjustment Layer” 2. Select Solid Color 3. A Color Picker dialog box will appear, Select the color you want from the Swatches Panel (You will see the ink dropper appear when you hold it over a color) 4. Press OK 5. Repeat Step 1 - 4 14

Add Swatches (Optional) Use Add DIC Riso Printer Swatches to Photoshop Swatches Panel. 1. Download “DIC Riso Swatches.aco” from (Link here) 2. In Photoshop, Window > Swatches 3. Select Import Swatches 4. Select “DIC Riso Swatches.aco” (Check your Desktop or Downloads Folder) 5. Select Open Now you have the DIC Riso ink color in your Swatches Panel 17

· Anatomy of Riso (Drawing + labels) 39
· Control panel (Picture and labels) · How does riso work? 40
The Risograph works by burning your image as a stencil, the master, which is wrapped around the Ink drum. The paper then is fed through the ink that goes through the Master onto the paper creating a print. You will have to run several prints for the ink to be fully on the paper. The master will be on that ink drum until the you clear it or the next master is made. How to clear the master: 1. Click home, 2. Click dual tone on the screen 3. Clear the master of your choosing. 4. Run prints through until ink is completely gone on page. You will burn through a lot of paper. Make sure to print proofs before you print on your actual paper. You can input how many proof copies on the pinpad in the control panel. · About Riso Ink Riso Ink is absorbed into the paper. If you are putting the print through the riso more than once to use a third color you need to wait 15 minutes or more until dry enough to put a second layer. You will want to lay darker ink (such as black) last, Feel free to experiment with different layering methods, but always give it time to dry. RISO INK also smudges very easily. If you get a smudge you can take a rubber eraser to pick up some of the smudged ink. You will have to run several prints to take away ink from a previous master and to make sure the ink fully comes down onto the page. What colors do we have? Teal, Medium Blue, Black, Bright Red, Yellow, Green, Fluorescent Pink. · (Get hex codes for these colors) Switching ink drums. 1. Open the front printer door. 41
2. Press the blue button and wait till the printer beeps. 3. Pull the drum out by the blue handle. 4. Once the drum is completely out, lift the drum up by both blue handles and put in a grey drum storage container. 5. To load, lift the new drum by blue handles and place it along the drum rail line up the arrow on the drum to the arrow on the rail. Push the drum back into the printer until you hear a beep. You will have to pull out the 2nd drum out and then close it back in till you hear a second beep telling you the second drum is loaded. 6. Close front printer door · Loading paper and paper types (Illustration and labels) This riso can print Letter and Tabloid Size paper. You can put paper that is any color as long as it's below (double check) lb to avoid jams. Depending on how thick your paper is you can switch the paper feed pressure adjustment lever. To load paper press the blue button to adjust the paper feed tray up and down. Load paper then adjust guides on the side to the edges of your paper. Then press the blue button again for the paper tray to come up. The paper should touch the grey pressure sensor. · How to prep your file… photoshop (screen shots) How to with layers 1. Separate your colors into separate layers or layer folders. 2. Mask the layer to make it black. (For your sanity you can left click and highlight your layer the color that you are printing *insert visual**) 3. To make a master from a layer or layer folder make sure the layer is visible and the layers that are not that color are hidden 42

RISO AT A GLANCE The Risograph printer is similar to screen printing. The risograph uses single colors to print designs from a master stencil. It uses wax paper to create a stencil called the master and soy based inks to print. File is sent from Computer or Scan Bed Master is created for each color by burning a negative image onto a waxed sheet. The master is wrapped around the drum. The ink is forced through the voids of the master. The paper runs flat and the drum rotates at a high speed to transfer the ink onto the paper. It takes 48 hours to complete a two color Risograph for a SINGLE sided print. Add 24 hours for each additional color! 49
ANATOMY OF RISO Before You Print 1. Wake the Riso by pressing the button 2. Switch the ink drum to the color you want. 3. Insert paper 4. Clear previous master To Clear Previous Masters 1. Click Home 2. Click dual tone, 3. Clear master on the drum of your choosing. 4. It will take a while for the ink to clear from the previous master. 50
