Litográfiában

Litográfiában is a Hungarian term that translates to "in lithography" in English. Lithography is a planographic printing technique that relies on the immiscibility of oil and water. In this method, an image is drawn onto a flat surface, typically a limestone slab or a metal plate, using a greasy substance like oil-based ink or crayon. The surface is then treated with a solution of gum arabic and nitric acid, which etches the non-image areas and makes them hydrophilic (water-attracting), while the image areas remain oleophilic (oil-attracting).

When the printing process begins, the surface is dampened with water. The water adheres to the hydrophilic areas but is repelled by the oleophilic image. Ink, which is oil-based, is then rolled onto the surface. The ink adheres only to the greasy image areas and is repelled by the water in the non-image areas. A sheet of paper is placed on the inked surface, and pressure is applied, transferring the ink from the image onto the paper, thus creating a print.

Litográfiában, therefore, refers to any activity, process, or state related to the practice of lithography. This could include the design of the image to be printed, the preparation of the lithographic stone or plate, the inking and printing stages, or the resulting printed artwork itself. The term is used within the context of art, printmaking, and commercial printing where lithographic techniques are employed. Its usage highlights the specific medium or process involved in the creation of an image.
