Adhesion resistance on lithography print method

Discheminc10 Jan, 2022Other

This is printing a lithograph on a solid, flat overside or a metal plate. The image parts are designed using a greasy material like pencil, lacquer, crayon, or tusche. The flat surface transfers ink to the paper in areas that mirror the pattern. To separate the grease-receiving image areas and water-receptive non-printing areas, a mixture of nitric acid and gum arabic, is put on the surface. This creates a resistadhesion in lithography because grease and water do not mix.
