Lithographic Graining Sand

Lithographic graining sand is a type of abrasive material that falls under the supply class of Abrasive Materials in the supply group Hardware And Abrasives. It is specifically used in lithography, which is a printing process that involves creating images on a flat surface, typically a metal plate, using oil-based inks.

Lithographic graining sand is used to prepare the surface of the lithographic plate by creating a fine, textured grain. This grain helps to hold the ink in place and allows for precise and consistent printing. The sand is typically made from finely ground particles of silica or other abrasive materials.

To use lithographic graining sand, it is applied to the plate using a graining machine or by hand. The sand is then rubbed onto the plate in a circular motion to create the desired grain pattern. After graining, the plate is cleaned to remove any excess sand before the printing process begins.

Overall, lithographic graining sand is an essential material in the lithography process, helping to create high-quality prints with sharp and detailed images.
