Affinity Publisher inserted picture DPI issue

[Jim Vormelker]

I reset the DPI of all images to be inserted in my Affinity Publisher file to 300 in either Affinity Photo or Corel PSP, and maintain the original size of the image in pixels, the crop or otherwise edit as needed. This is verified in File Manager > Properties and Corel PSP Image information. 

However, in Affinity Publisher, the imported images all show a much higher dpi, mostly to nearly always well above 600. The printer [Lulu] reports this in its file upload utility, as does Affinity Publisher.

How, please , do I correct this?

Paragraph 1 - it is also verified in File Manger when the operation is performed in Affinity Photo.

You would need to maintain the original size in both pixels and physical dimensions if you want to maintain the same DPI.

If you keep the same number of pixels, but they occupy a space on the page that is physically smaller, then the DPI must increase. 

If you want the same DPI, in a smaller space, you would have to decrease the number of pixels.

Or, if you use embedded files, you could Rasterize the Placed images to the document DPI if that's also 300.
