Cloth/ PU Leather
For a unique look and feel, it’s possible to make the hardcover case for a casebound book using cloth or leather instead of printed paper. It’s most common to use faux-leather polyurethane (PU) instead of actual leather, although some companies may offer real leather binding as well.
These books are made the same way as standard casebound books, just using cloth or faux leather wrapped around grey board. However, it’s not possible to print on cloth or faux leather with the offset press, so foil stamping is commonly applied instead.
