Double Fan adhesive binding (DFAB) is a library binding style method that utilizes polyvinyl acetate glue (PVA), instead of thread for the binding. This binding method places a microscopic bead of glue on either “side” of the pages after notching the spine edge. This creates an exceptional lay flat quality and was developed as a “Smyth Sewn alternative”. We do not recommend an edition to be bound with this method if the interior pages are a coated paper stock such as an 80 or 100 lb text gloss.
DFAB is great for a family history style genealogy edition which will be using uncoated text weight paper on the interior of the book, and requiring a rounded spine edge. One of the big advantages here is it is also ideal for short run lengths. Single sheet collated book blocks such as what you would get from a copier or a digital print stream work great. You can also use folded and gathered signatures with this style of binding.
