How to use AI for Diffa Region

Adobe Illustrator (CC 2018 and newer) — File → Open; after that it is normal work: select by color, change strokes, replace label fonts.
Affinity Designer — opens the file as a PDF document; on import enable keeping text as text, otherwise the labels will arrive as curves.
CorelDRAW and Inkscape — File → Import; full compatibility with Illustrator's own effects is not guaranteed, but geometry and text carry over.

FAQ: AI for Diffa Region

Can I open AI in CorelDRAW?

Yes, CorelDRAW supports AI file import.

What Illustrator version is needed?

Files are compatible with Adobe Illustrator CC 2018 and later.

Does the file contain object names?

Yes, as a hidden catalogue — but it works in a PDF viewer, not in the editor: searching for a name takes you to its spot on the map. Inside Illustrator the name arrives split into separate fully transparent letters, so it never shows up as a readable name in the Layers panel. If you need the name as an editable label, take SVG: there the name catalogue comes as its own layer.

Are layers preserved?

No native Illustrator layers: the file is written by the PDF engine and arrives as a single artboard. Objects are easy to isolate with Select Same (fill or stroke) and then move onto your own layers.

Does the file arrive in RGB or CMYK? How do I prepare it for a print shop?

In RGB. Convert to CMYK in Illustrator under your print shop's profile: File → Document Color Mode → CMYK Color, with the profile set in Edit → Color Settings. We deliberately run no server-side auto-conversion: it turns black labels into four-ink black (295 % total ink in our measurement), and prepress sends such a file back. For vectors already in print colours take CDR: device CMYK, black on the K plate alone.
