Photobook or "Classic Photobook" - a photobook printed on photo paper, the cover is opened 180 degrees, and a plastic layer is used between the pages.
A real, classic photo book is printed on the same equipment as regular photographs: on the “mini-laboratories” of chemical printing. Each spread is printed as a separate photo, then it "beats" (bent in the middle). Next, the turns are glued on a tight base. It can be cardboard or plastic. Photobooks on a plastic base are considered more reliable, since this material, unlike cardboard, does not absorb moisture from the air, thereby protecting the pages from deformation when temperature and humidity change.
