1. You can have one layout on one level (but one page or two-to-one layout) or multiple layouts on one level. If the background pictures are the same, it is more convenient to use one layer and one version.

2. The front cover should be opened at 16, and the back cover should be opened twice at 16.

Yes, if it is imposed, it should be, but there are left and right points. For example, when the back cover and the cover are put together, it means that the back cover is on the left, the cover is on the right, the first page of the inner page is on the left, the right page is the penultimate page of the inner page, and so on. If you don't master it well, you'd better fold a sample first, then mark it on the page yourself, and then make a picture against it.

Page numbers should be based on your actual situation, because some directories have no page numbers. Remember the number of pages, a piece of paper is four pages, and it must be a multiple of four. Do not print out 14, 18, 22 and other pages. )

5. Just save the radicals as ai. If there are few pictures, you can put them in one file. If it is too big, it should be stored separately, otherwise it will run too slowly and the software will get stuck easily.
