Is it possible to ensure the page count is divisible by 4 by inserting blank pages AND ensure the last page has certain content?

For context, a client is wanting to print their book in an A3 printer where the pages will be folded in two, and on the verso of the last page they want to add their company info etc (like a back cover).

I suspect their best option is to use Adobe Acrobat Pro or something to manually add the blank pages, or print the outside cover separately from the book’s inner contents.

Thoughts?

You could also use JavaScript to check the final page count and then reconvert the document with some additional style rules for the blank pages.

Aaah thanks. Very cool.
