The inked image is transferred directly to the page, resulting in type or images that may actually be depressed or debossed into the paper by the pressure of the press. Lignin that is left in pulp causes paper to age and yellow over time. Linen finishes are embossed after the paper comes off the paper machine. The more lines per inch, the more detailed the printed image will be. The image to be lithographed is created on the plate with greasy material that repels water.
Water is run over the plate, and the non-image areas absorb it.
When the oily ink hits the plate, it's attracted to the similarly greasy image, and repelled by the rest of the wet plate. This process is now used primarily for limited-edition art prints.
