N is 8 but 16 is cheaper.
You can use a larger press with multiples of 16 but need a different press for multiples of 8.
That is how I managed to increase the page count of Model Engineer from 60 to 68.
The printing cost was slightly cheaper but the extra £400 contributor cost had to be found.
(£50 per page.)
That is why we try to fill some of the extra pages in house with Roedean, visits and exhibition reports.
This saves £50 for every page and keeps me within the contributor budget.
