I have started using Affinity Publisher after using for a long time other legacy Serif products (PagePlus, etc) and being a beta tester.
I found a little mistake in translation when creating a new document. The words "press ready" have been translated as "Premi Pronto", it should be translated as "pronto per la stampa" .
As it is, it is a bit misleading just suggesting to push down a "pronto" button 😃
The help guide is already correct as it states "...Pronto per la stampa (stampa professionale CMYK)..."
