Litho Stone Graining Procedure

Takach Litho Stone Levigator

The Graining of litho stones requires an abrasive material such as carborundum grit and a levigator. Carborundum grit is used in place of quarts and sand abrasives for graining lithographic stones. The graining procedure should be begun with coarser grades of carborundum grit. The sludge created when graining litho stones should be removed and replaced with new grit when it becomes sticky and dry. To remove the prior lithographic image completely from the litho stone, use a coarse grit until the dark areas of the image become light. Rinse the litho stone, levigator and your hands to remove all particles of abrasives before proceeding to finer grits. To finish the stone use finer grades of carborundum grit until the tooth or grain and finish of the stone's surface are ideal.
