Formatting PDF page size
Hello, this is yet another question about formatting.
I want to publish some sort of magazine in A4 format. I created it using Microsoft Publisher 2010 and set the page size to A4, which is 21x29.7cm in this software.
Now when I want to print it through lulu, after selecting A4, lulu tells me my pages need to be 21.3x30.33cm (document size). It's slightly larger than what my document is, so I suppose that's fine if I submit it without changing anything, at best I'll have a thin white space around the pages, at worst it'll be slightly reduced.
But then there's the trim area (20.98x29.69cm, which is very slightly inferior to my page size) which should encompass all of the page or the edges might be cut off from what I understand. Now if I submit my document without changing anything, will the edges be cut off or will the whole page be scaled down a bit? Also, when downloading the template, there's only mention of those specifics relating to the front and back cover pages. Does that apply only to those or to the whole document? I plan on submitting a fully embedded PDF file, and I have to mention that in my Publisher file the pages are 100% filled with material, that's why I'm worried some will be cut off.
