web to print aka px to mm

[fruid]

I made a flyer with affinity designer that my client wants to post on social media, that's why I "social media story post" as a layout. Now they tell me they want to print is as well so I need to enlarge it to DIN A4. The dimensions are of course wrong and I need to enlarge it, also convert pixels to millimetres, change the color settings etc.

So since (I think) I cannot do both types in one document, I saved the document as a copy and changed the units to millimetre and RGB to CMYK in the settings. So far so good, but I cannot just change the dimensions of an artboard to be width 210mm and height 297 mm, it always jumps back to the original pixel.

Please tell me there's an easy way to do this.

I think I postet about this issue before actually…

never mind, it works when I set it in the Transform-panel, not in the export dialogue directly, that's OK, all good.

Try Export persona, and two export setings for one slice/document.
