Type of limestone with hard fine grain
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.[1]
The term "sublithographic" is sometimes used for homogeneous fine-grained limestone with a somewhat coarser texture.[2]
