Affinity Publisher pdfs rasterising whole page including text

[Affectus]

Again, I am finding that, when I create a pdf from my Affinity Publisher document, some of the pages are being completely rasterised. This time it is four out of 24 pages. I can't understand why. It doesn't matter what my pdf settings are the same thing is happening. Does anyone have any ideas what may be causing this.

What does the Layers panel show for those pages, in your .afpub file?

Thanks for the quick response. I'm not sure what you're asking me though.

In your .afpub document, view each of the pages that end up rasterized. Look at the Layers panel. What does it show? Is everything vector as you expect? 

Do you have anything on the page that might cause rasterization during Export, such as Adjustment layers?

[Affectus]

Everything is fine in layers, but I've worked out what it is! On each of the errant pages I have placed at least one linked .afphoto image that has an adjustment layer applied in Photo ie. I hadn't flattened the image. I have now done this, and the pages are reproducing as they should.

As long as the Adjustment layer was nested into the Linked file it should have worked. But if you had it as a separate layer it could cause the issue you saw.

Yes, it was as a separate layer, but in Affinity Photo, not Publisher! At least I know now. Thanks for your help.
