I have made a 24 page document slightly smaller than A5 with margins Inside and Outside set at 20mm. When I pull together the document using Utilities - Build Booklet - the new document's margins are not the same: the Left inside and Right outside are much wider. Can you give me any tips about what I can do to ensure that the margins come out evenly. I am printing the new booklet document in landscape to ensure that the pages come out fully. Thanks. This is fairly urgent. PS I don't need any extra inside distance as it is 2 up saddlestiched (stapled in the middle).
