You said in your article that the total number of pages in a print-on-demand book needs to be a multiple of four. Why is that important?

Answer

Printing is done as four pages in one press. Then they are cut into four separate pages. This is why your document needs to be a multiple of four.  

If you end up with something less than a multiple of four pages, you need to add the appropriate number of additional blank pages.
