Blind stamp

A blind stamp ('blind' meaning uncoloured) is an image, design or lettering on an art print or book formed by creating a depression in the paper or other material.

It is the opposite of embossing which refers to a design created by raising the paper above the surrounding area.

It is also distinct from foil stamping, which is a depression that is filled with a thin layer of metal, usually gold.

Occasionally seen on the covers and spines of older books, blind stamps may be quite decorative.
