Overprint for Affinity

Prints the image in up to three flat inks, one over the other on paper, in the style of a risograph. The effect works out how much of each ink every color needs so that the inks, overprinted like translucent ink, come as close as possible to the image. Each plate gets its own speckled grain, drifts a little out of register and inks unevenly, so the copy has the specks, overlapping colors and shifted edges of a real print.

5 presets to start with

Pick one in the Filter Gallery window and adjust it from there. Every control can still be changed.

  • Overprint for Affinity: Default

    Default

    Fluorescent pink, blue and yellow on natural paper, the typical inks of a stencil duplicator. Where they overlap, they make orange, green and almost black.

  • Overprint for Affinity: Teal Orange

    Teal Orange

    Two inks, teal and orange, on cream paper, with “Ink 3” set to “no color”. Where they overlap, a very dark green appears.

  • Overprint for Affinity: Navy Red

    Navy Red

    Navy blue and coral red on warm white paper, with a little more density and contrast. Overprinted, they make a dark plum.

  • Overprint for Affinity: Mono

    Mono

    A single black ink on cream paper, with more contrast, coarser grain and no misregistration. The uneven inking leaves the shadows a mottled gray.

  • Overprint for Affinity: Sunset

    Sunset

    Fluorescent pink, sunflower yellow and violet on cream, with the plates further out of register. They mix into oranges, warm browns and lavender.

What each control does

They have the same names as in the Filter Gallery window.

Ink 1
The first ink. It’s always printed, and its plate stays in place while the others drift around it.
Ink 2
The second ink. With “no color”, the print uses one ink fewer.
Ink 3
The third ink. With “no color”, it’s left out, as in the two-ink presets.
Paper
The paper color, with a subtle fiber texture. The inks are worked out over it, so the lightest parts of the image stay bare paper. With “no color”, only the ink remains, over transparency.
Density
How much ink each plate lays down: with less, more paper shows and the colors get paler; with more, the print gets heavier and darker.
Contrast
Separates light and dark before splitting the inks: more contrast, cleaner paper in the highlights and fuller ink in the shadows.
Misregistration
How far the other plates drift from the first, in thousandths of the longer side of the image. It shows as colored edges where the inks don’t line up. With a single ink it does nothing.
Grain
The speckle of the screen. At 0 the inks are smooth, like transparent layers of color; at 1 every tone is built from specks.
Grain size
The size of the specks, in thousandths of the longer side of the image.
Uneven inking
Large lighter patches and horizontal roller streaks in the ink, plus more visible paper fibers.
Seed
Shuffles the grain and the inking patches, and changes the direction and distance the plates drift.

Tips

  • Two inksSet “Ink 3” to “no color” for a two-color print: the effect recalculates the mix with the two inks left. A warm ink with a cool one, as in Teal Orange, gives a dark color where they overlap, so the image keeps its shadows.
  • Clean or wornFor a cleaner print, lower “Misregistration” and “Uneven inking”. For a worn copy, raise them and try other values of “Seed” until the drift lands where you like it.

Installation

It installs in a minute

The installer copies the plugin into the Affinity plugins folder and turns on the setting Affinity needs to load it.

  1. Download the installer

    Download FilterGallery-Setup.exe. It doesn’t need administrator permissions.

  2. Open it

    Click “OK”: it copies Filter Gallery into Affinity and turns on “Allow "Unknown" plugins to be used”, which Affinity needs. If Windows shows “Windows protected your PC”, click “More info” and then “Run anyway”.

  3. Restart Affinity

    Choose Filters › Plugins › Visual.af › Filter Gallery with a pixel layer selected. The effect is applied to that layer, so duplicate it first with Ctrl+J if you want to keep it.

  1. Download the installer

    Download FilterGallery-Setup.pkg. It doesn’t need administrator permissions.

  2. Open it

    Click “Continue” and then “Install”. It copies Filter Gallery into Affinity and turns on “Allow "Unknown" plugins to be used”, which Affinity on Mac needs.

  3. Restart Affinity

    Select a pixel layer and choose Pixel › Filters › Plugins › Visual.af › Filter Gallery. The effect is applied to that layer, so duplicate it first with ⌘J if you want to keep it.

Frequently asked questions

Does it work on a Mac?

Yes. Download the Mac installer (FilterGallery-Setup.pkg): it works with Affinity 3 on Macs with Apple Silicon or Intel. The installer is signed and notarized by Apple, so it opens without warnings.

Does Windows warn that it isn’t safe?

It can happen. Because Filter Gallery is new, Windows SmartScreen doesn’t know the installer yet and may show “Windows protected your PC”. It is 100% safe: click “More info” and then “Run anyway”.

What if Filter Gallery doesn’t show up in Affinity?

Go to Settings › Photoshop Plugins, turn on “Allow "Unknown" plugins to be used” and restart Affinity. Also select a pixel layer before you open the Plugins menu: the filter only works on a selected pixel layer.

Which version of Affinity do I need?

Affinity 3, on Windows 10 or 11 or on a Mac.

Does it work with text, vectors or groups?

Like every filter in Affinity, it works on pixel layers. To apply an effect to text, vectors or a group, duplicate it and turn the copy into pixels first (rasterize it).

Does it create a new layer?

No. Like every filter in Affinity, the effect is applied to the selected layer. Duplicate it first with Ctrl+J (⌘J on a Mac) if you want to keep the original, or undo with Ctrl+Z (⌘Z).

On how many computers can I use the license?

On three. If you change computers, you can free one up from the window itself with your purchase email.

Does it need the internet?

Only to activate the license and check for updates. The effects are calculated on your computer and your images never leave it. Offline, the license keeps working for 14 days.

How do updates work?

When there’s a new version, the window shows a notice with an “Update” button. Affinity uses the new version the next time it starts.
