Define lithography?لیتھوگرافی کی تعریف کریں؟

Lithography is a printing process in which a flat stone or metal plate is used to transfer an image onto a printing surface. It is a widely used printing technique that allows for the production of high-quality printed materials, such as books, newspapers, and packaging materials.

In lithography, an image is drawn or transferred onto a flat plate using a chemical process. The plate is then washed with water, which is absorbed by the blank areas of the plate but not by the image areas. An oil-based ink is applied to the plate, and it adheres only to the image areas. The plate is then pressed onto a printing surface, such as paper, transferring the image onto the printing surface.

Lithography is a versatile printing process that can be used to produce a wide variety of materials, including books, brochures, posters, and packaging materials. It is a high-quality printing process that is capable of producing accurate and sharp images and text.
