A web offset printing machine is a type of printing press used for high-volume commercial printing. It is designed to print large quantities of newspapers, magazines, catalogs, and other publications efficiently and quickly. The machine starts with a roll of paper called a web. The web feeding system unwinds the paper roll and feeds it continuously through the press. A web offset press typically consists of several printing units. Each unit contains a series of printing cylinders and rollers that transfer ink onto the paper. The number of printing units can vary depending on the number of colors and the complexity of the print job.
