• Remember that if you are running a color to the edge of your page, bring it over the edge of your document setup page by 0.125" (1/8"). This will eliminate the chance of getting a white edge down the side of your page from press shift.

By creating a bleed (Extra Image) around the outside of the page you allow trimming to have a variable. As signatures are folded in the bindery. The inner pages are actually shorter than the outside pages. They are shorter by the thickness of the spine. Having extra bleed can allow trimming to be larger to save type that may be really close to the edge of the page. All live type should be a minimum of 1/4" from the trim. We have seen many publications where designers like to have folio's only 1/8" from the trim. This can cause serious problems on a 96 page magazine where the spine itself may be 1/8". Basically cutting off the folios on the centre pages. Having extra bleed would allow us to overtrim slightly and not cut off folios.
Tiling and shingling is not an option on magazines. It is used mostly for books that have a white spine. Magazines have many crossovers. Tiling/shingling would have a negative effect on those pages.

Tiling and Shingling is the process of moving the inner most pages outward by the thickness of the spine. This helps to create folios that line up correctly on the outer portion of a book. When creating a magazine, there are many crossovers, and by moving pages outward would have a drastic negative impact on those pages. The option is to reduce the physical size of the inner pages. Imaging them at 100% and reducing to maybe as small as 97% width for the inner pages. This of course is not feasible for standard magazines. It can however be done manually where needed.We have used this feature when doing a 128page saddle stitch magazine. 96 pages is usually your cuttoff between saddle stitch and perfect bound.
