Double sidedPrinting the back adds 60% per colour. Backs run after the front has dried overnight, so add a day.

Ink colours

Twelve drums on the shelf.

Riso ink is translucent, so two colours printed over each other make a third. Tap any two swatches below and the mixer shows roughly what the overprint will look like on our house paper.

Blue over Fluorescent pink

Where the two circles cross is the overprint. It is always darker than either ink, never lighter, and it is the cheapest third colour you will ever buy.

Paper stocks

Five papers we trust in the machine.

Risograph needs uncoated, absorbent paper or the ink never dries. These five feed reliably, take two passes without curling, and are all held in stock. Prices are per 100 sheets on top of the print price.

Turnaround

Three working days as standard.

The clock starts when your file passes preflight and you have approved the proof photo. Days are working days, Monday to Friday, and the studio closes for the last week of December.

File preparation

Eight rules that save a reprint.

Riso is not a digital press. Each colour is a separate stencil burned from a black and white image, so we need your file split the way the machine thinks. Follow these and preflight passes first time.

  1. One greyscale layer per colour

    Send each ink as its own page or layer in pure greyscale. Black in the file is 100% ink, white is bare paper. Name the layers after the drum: 01-blue.pdf, 02-pink.pdf.

  2. Keep tints between 10% and 85%

    Below 10% the stencil drops out to nothing; above 85% the ink floods and looks the same as solid. A 30% blue over a 30% pink is where the good stuff lives.

  3. 300 dpi, exported as .pdf

    Bitmaps at 300 dots per inch at final size. Vector shapes and live text are fine. No screen-colour files, no four-colour process, no spot channels.

  4. 3 mm bleed, 5 mm safe zone

    Add 3 mm past the trim edge and keep anything important 5 mm inside it. The feed rollers drift a millimetre or two on every sheet.

  5. Expect 1 to 2 mm of misregistration

    Colours will not sit exactly on top of each other, and thin outlines that rely on it will look broken. Design so a slip reads as charm, or trap it with a knockout.

  6. Leave a 10 mm paper margin on the feed edge

    The rollers grip the top of the sheet and leave marks in heavy ink there. Keep the short top edge light, or plan for us to trim it.

  7. No large solid floods on the reverse

    Two-sided jobs with big solids on both faces will smear because riso ink never fully cures. Keep one side lighter than the other.

  8. Send a colour mock-up too

    A flattened screen image of how you imagine it, with the ink names written on. It is the only way we can check your separations are the right way round.

Honest bit

What riso does well, and what it does badly.

A risograph is a 1980s stencil duplicator with beautiful ink. It is cheap, fast and vivid, and it is also messy, imprecise and allergic to some kinds of artwork. Read both columns before you send us a job.

Good at

say yes to
  • Flat, punchy colourFluo pink and blue cannot be reproduced by an inkjet. The ink sits on the paper rather than in it.
  • Short runs at long-run pricesFifty posters for £58 is not a typo. A master costs pennies and the ink is cheap.
  • Halftones and grainPhotographs converted to a coarse dot or stochastic grain look better on riso than on any other press.
  • Overprints as free coloursTwo drums give you three colours, three give you six or seven. Layers are the whole trick.
  • Low footprintSoy ink, no heat, no solvent, no plate chemistry, and recycled paper goes through fine.

Bad at

talk to us first
  • Tight registrationColours drift 1 to 2 mm. Outlined text and fine multi-colour logos will look drunk.
  • Large solid floodsBig areas of 100% ink go blotchy, roller-marked and never quite dry. Tints under 85% behave far better.
  • Exact brand coloursThere are twelve inks. None of them is your corporate teal, and mixing does not work like paint.
  • Smudge-proof finishesRiso ink stays soft. It rubs onto fingers and facing pages, especially on coated or glossy stock, which we will not run.
  • Photo-real colourSkin tones, gradients and full-colour photography come out as posterised art prints, not proofs. Sometimes that is lovely. Sometimes not.
