Perforated interiors are produced with a tiny line of perforation that allows for pages to easily be removed from the book. Perforations are available in Color (50# only) in limited trim sizes. Perforation carries an additional charge per page printed.
At this time, perforated titles are not eligible for sale through traditional distribution channels. Titles with perforated pages may only be ordered directly through publishers’ accounts.
Additional Perforation Requirements:
(only available in Color 50# for 6 x 9, 7 x 10, 7.5 x 9.25, 8 x 10, 8.5 x 11)
Inside Margin: Recommended minimum 1” (25 mm)
Margins: Recommended minimum 0.5” (13mm) on outer 3 edges
(Perforation of interior pages is available for Color perfect bound products in limited sizes. Within a publisher’s designated title, the…perforation line would be placed 0.5 inches (12.7 mm) from the binding edge, positioned parallel to the spine, and applied to all pages of an interior.)
