Perfect binding
 

–noun Bookbinding . a technique for binding books by a machine that cuts off the backs of the sections and glues the leaves to a cloth or paper backing.

Also called adhesive binding

How do you say it in Spanish, ¿encuadernado adhesivo?

What about encuadernado rústica?

Hey, that's right! :applause: ("Encuadernado en rústica")
Thank you very much! :) (Just add the "en" as it is a 'cliché', per Moliner, En rústica. Se aplica a la manera de estar encuadernado un libro cuando solamente tiene tapas de papel o cartulina. :thumbsup:

I'm glad I could help! Working with books all day every day has made me well acquainted with different types of bindings :D

Pues, ¡reitero mi agradecimiento! (It is funny, because I knew the term, but didn't click...) So, glad that you are around here! :)
