In particular in case of a cutting edge it might be useful in an automated printing workflow to prevent this color get printed at all.
This reminds me to bad experience: A client delivered a logo file with a color swatch named "gold". An advertisement using this logo was sent to a few newspapers, they all printed fine except one, which appeared different. Finally it came out it was this printer's RIP which had manually set its own definition to translate an incoming spot color named "gold" into the 4-c process.

Hi Sean,
Thank you very much for all your research! I tried a bigger size and it worked as you said. If I notice anything strange with the transparancy-export again, I’ll let you know.
Still a very happy Affinity-user! ;-)
