Before you order, check your page count. (Not counting front and back cover) Your page count must be a multiple of 4, this includes blank pages as well. If the page count is an odd number (333, 251,179, etc.) we will add blank pages to make it come out correctly. The price is for the maximum number of pages. If your page count is less than the maximum, your price will be less. Your price will not go up. You can check the price in the portal after the job is moved to Pre-Press if you need to adjust your PO. If your Cover prints on both sides please let us know, so we do not add those to the page count.
