InkQuest pre-press plugin for Adobe Illustrator

InkQuest is a plugin for Adobe Illustrator, previously part of the Astute Graphics subscription service. It was announced that it would be removed from the subscription in October 2024. Following the notification period, it became freely available here, April 2025.

InkQuest provides the following functionality for pre-press and print operators, including:

• Swap channels (as a live effect or filter)

• Generate separations

InkQuest is compatible with:

• Adobe Illustrator 2020.3 to 2025

• Windows 10 (64-bit only) & 11

• macOS 11 to 15 (Apple Silicon and Intel hardware)

Astute Graphics does not offer support for other variants of Adobe Illustrator and/or operating system.

1. Quit Adobe Illustrator (if running).

2. Delete the plugin from the Illustrator Plug-ins folder.

3. Start Illustrator to ensure it runs once more without issue.

4. Follow the instructions above once more, paying special attention to:

   • Checking your installed version of Illustrator is 2020.3 (v24.3) to 2025 (v29).

   • Download for the correct operating system.

Once the InkQuest plugin is installed, the various functions are accessed using the following menus and/or windows.

Swap Channels

Swap Channels is available as both a non-destructive live Effect and permanent Filter. With the object selected, either follow Effect > InkQuest > Swap Channels... or Object > Filters > InkQuest > Swap Channels...

Swap Channels does what it says on the tin. It allows you to swap ink, color and alpha channels—plus allowing your copy levels from one channel into another.

Ideal for working in CMYK documents, it will also cater for RGB artwork.

Quick Separations / Overprint Preview / Ink Coverage

⚠️ These functions are only accessible in CMYK documents which are being viewed in Overprint Preview mode (View > Overprint Preview).

A single modal dialogue window provides these functions and may be accessed via View > InkQuest Output Preview > ...

Once the window is open, it is possible to quickly change between the various output preview modes by selecting from the Preview pull-down menu.

Quick Separations was subsequently duplicated in Illustrator natively. You may wish to use the Window > Separations Preview… instead.

Full Separations

⚠️ This functionality is only relevant to CMYK documents.

Full artwork separations are accessed through a panel. To access the panel, open Window > InkQuest > Separations Panel...

Once the Separations panel is open, it may be docked as standard. If the artwork has not yet been fully separated, or a full separation has been released (please refer to the product movies for full information) this panel will only give the option to Generate Separations. Click on this button to produce fully separated artwork in a new document.

Once the artwork is separated, the panel changes, providing control and adjustment of the separations and printer marks.
