The diagram describes how to print newspapers through a method known as lithography.
Overall, it is clear that there are six main stages in this process, beginning with attaching a piece of paper to a rotating cylinder and ending with drying ink on newspapers with hot and cold air.
The process of lithography commences when paper is attached to a plate cylinder which rotates clockwise, helping the paper pass through dampening rollers first. At this stage, a mixture of water and chemicals from the dampening rollers makes non-printing areas on the paper wet. The paper is then forced through a set of ink rollers which press ink on the printing areas of the paper.
The process continues when the paper with ink on the printing areas is transferred to a blanket cylinder, which rotates anticlockwise, in order to squeeze out water from the paper and to make the image areas picked up. Subsequently, the image is pressed onto the paper when it is forced through an impression cylinder. Finally, the printer paper moves along a conveyor belt to the drying section where hot and cold air is blown over the paper to dry the ink before the newspapers are finished.
