Reply To: Difference between Slug and Bleed

Tim: Sam needs two same pages with (possibly) different slug and/or bleed sizes to be lined up.

Sam: You can place your files and have them automatically cropped to the Page size, which is the only constant you have. After placing, you can enlarge their frames to display the slug, without moving the page off its position.

It appears to be the same as bleed area covered […] If it's the bottom, then why does the New document dialog box allow you to make slug info on all four sides?

Without knowing what Adobe or David told you, but slug is there to allow any amount of extra information for the printer and/or binder and/or co-workers. Bleed *is* required, and you cannot (safely) put information in it like “This side should point up”. But you *can* put that line safely into the slug — on the top, bottom, or sides, whereever you want.
