A lithograph is a type of printmaking in which an image is transferred to a flat surface, usually paper. The process involves engraving a design onto a flat stone or metal plate and then using that plate to transfer the image to the paper. Engraving is the process of carving or cutting into a hard surface, such as stone or metal, to create a design. Printing is the process of transferring an image from a plate to a surface, such as paper, using ink.
