To determine the spine width of a book, you divide the paper PPI into the number of pages in the book. An example is a 250 page book using Plainfield opaque 50#
smooth which has a PPI of 526. Divided 250 by 526 which equals a spine width of .4752". In this case, you would use the .5” spine. Now select the Spine width for
the book and hide the others: Special>Conditional Text>Show/Hide>SpineSize(-->Hide:)>Set . Move the changed Conditional text settings to all files in your
book by opening
the book file with the spine.fm still open and File>Import>Formats the Conditional Text Settings (ONLY!) to the book files.
