Lithographic limestone

A lithographic limestone printing plate after use to print a map. Note the uniform fine texture of the stone.

Lithographic limestone is hard limestone that is sufficiently fine-grained, homogeneous and defect-free to be used for lithography.

Geologists use the term "lithographic texture" to refer to a grain size under 1/250 mm.

The term "sublithographic" is sometimes used for homogeneous fine-grained limestone with a somewhat coarser texture.
