You’ve got your perfect binding. Other people use broadsheets. Life magazine is one big broadsheet and you stitch down the middle and then fold it. When you do the signature binding you have to rearrange the content into a new position via a process called imposition: you put page number 2 as the same sheet as page number 98 if in a 100 page book. Lots of magazines, especially older ones, and lots of books, historically and currently work around the signature binding basis. When I realized this I was doing some collage work, somewhat physical, I don’t want to lose all my hand skills. Anyway I reduced the process to: you open up the signature and you go through the spreads as full spreads! and every once in a while you wind up with these juxtapositions never meant to be seem but they share the same physical space and speak into each other in a new truth in a “whoah that’s amazing they’re beautiful, interesting, funny”.
