Nipping is the practice of cutting book pages along the spine to create a neater appearance and prevent fanning out, usually done either as part of binding or by hand. Nipping can also refer to trimming edges uniformly across every book page.
Nipping, in bookbinding terms, refers to trimming the edges of book pages for aesthetic and preservation reasons, as well as to prevent fraying over time. Nipping can be performed manually or automatically using machines; typically, this step comes after attaching the cover.
Nipping refers to trimming printed pages after assembly for a neater appearance and overall cleaner presentation. Though this may seem like a minor aspect of book printing, professional book printers take it very seriously and will only consider taking on jobs with pages that have been nipped prior to printing them out.
Nipping is an integral component of bookbinding. First and foremost, nipping ensures all book pages have equal sizes; this serves both aesthetic and functional reasons – uneven pages look unprofessional; and having different sizes makes binding it harder.
Nipping can give books an attractive, clean appearance by smoothing away rough or jagged edges on their pages, which may give them an unfinished appearance. Nipping gives it a more professional look by creating cleaner pages for readers.
