Perfect Binding is a type of binding commonly used in paperback books, soft cover books, real estate books and catalogs.
After the books are collated the “Book Block” is placed in a PUR Perfect Binder, the spine gets sanded and the cover is added and glue is applied to the spine. The Perfect Binder will combine the cover and text and lastly 3 knife trimmed.
Perfect Binding is best when your book 28 pages or more.
It is best to have a thicker paper for the cover or “cover weight” paper and the text usually prints double sided on thinner or “Text weight” paper.
Sumi uses PUR Glue which is much stronger and pages lay flater than hot melt glue especially when printing on coated papers and there is many pages. Many of our competitors are still using hot melt glue.
The primary benefits of perfect binding books are that they look professional, offer great visual appeal and you can print on the spine.
