The provided diagram elucidates the intricate process of lithography, which serves as a prominent technique in the production of newspapers.
The process entails a series of six distinct stages involving the application of water and ink, transferring of images using cylinders, pressing paper for image transfer, and the final drying phase via hot and cold air.
Initially, unprinted paper is elevated by a plate cylinder, followed by the action of dampening rollers to moisten the paper for stabilization. Subsequently, ink rollers come into play to imprint images onto the paper, with the flexibility to adjust for varying printing requirements over time.
The image-bearing papers are then conveyed to a system comprising three essential cylinders. The first in line is the transfer cylinder, responsible for receiving the inputs. Next, the blanket cylinder receives the inked images from the ink rollers and flips them to their correct orientation. Finally, the impression cylinder firmly presses the image onto the paper to ensure lasting prints. The printed papers are then transported by transfer cylinders and subjected to a drying process facilitated by varying-temperature air.
