Outputting master PDF for print (from Affinity Publisher)

[benged123]

So much to learn. I think I've got the document prepped right, using the one-pager template from Lulu.com. I'm outputting the final PDF. I see Affinity is giving me LOTS of choices in the output. Here is a screenshot of my choices, and the ones I've ticked off (some were already ticked off by Affinity, left them as they were) ... the one key choice was 'Area', default setting being 'All Spreads'; I changed this to 'All Pages' coz I think that's what Lulu wants. (Would like to know if it makes a difference, because I've see other POD sites requesting 'pages' rather than 'spreads'.)

I set the 'Rasterize' to 'Nothing'. There is only text and black and white photos in the document.

I had set the document itself at 300 dpi. Some of the photos in the document were 400 or 600 dpi. Do I want to downsample the photos that are higher than 300 dpi? Or just leave them as is. I think I added dpi (in Preview) to some of the archival photos in the hope of getting more of, or holding, the resolution. 

This is a book of short stories with archival photographs. Printed on their best paper stock, but wanting to keep the text like what one would find in a good quality hardcover novel (but not glossy like a tabletop photo book). Any advantage to making the document more than 300 dpi? Or outputting it at more than 300 dpi to PDF?

 

All ears ... Ben

I apologize to Mike Loader. I just read the appropriate page in his Expert Guide to Affinity Publisher. Very helpful. I think a lot of my questions above answered. But it would still be comforting to hear any other suggestions from the enlightened.
