Adobe Colour Print Utility

That's a good question, it seems the very useful ACPU has not been updated for a long time, I hope someone from Adobe may be able to address this request.

Note that I did read from a fellow volunteer here that it did actually work on a 64 bit version of macOS.

Ignore Catalina Warning Message

On the Adobe site you will see a warning message to the effect that the utility won't work in macOS Catalina. This is incorrect! We have tested it and it works fine, apart from the Apple Security Message when attempting to run the Utility for the first time to the effect that it hasn't been 'notarized'."

Is it not downloading (or not starting) because of macOS security perhaps? 

Please insert a screenshot of the dialog you get when attempting to download

Meanwhile, if you're using i1profiler you can print directly from that application.

I hope this helps
