Web16 jun. 2024 · To generate an image, lithography employs basic chemical processes. The positive half of a picture, for example, is a water-repelling material, but the negative image is water-retaining. When a suitable printing ink and water combination is applied to the plate, the ink adheres to the positive image while the water cleans the negative picture. WebThe original form of lithographic printing - stone lithography -. relies on a particularly harsh chemical mix of asphaltum (a tar-like product), rosin, pure nitric acid, and mineral spirit solvents. Many of these materials are suspected or known carcinogens and neurotoxins. Cancer, brain disease, birth defects in offspring, and infertility.
