Newspapers are printed using a process called offset lithography. This process involves transferring ink from a metal plate to a rubber roller, which then transfers the ink to paper.
Step 1: Prepress
The prepress process involves preparing the text and images for printing. This includes typesetting, formatting, and creating printing plates.
Step 2: Platemaking
The printing plates are made by exposing a photosensitive metal plate to light. The areas that are exposed to light will be etched away, leaving the image areas raised.
Step 3: Inking
The printing plates are then coated with ink. The ink is applied to the raised areas of the plates, and the excess ink is removed.
Step 4: Printing
The paper is fed through the printing press, and the ink is transferred from the plates to the paper. The paper is then dried and folded.
Step 5: Postpress
The postpress process involves finishing the newspapers and preparing them for distribution. This includes binding, trimming, and packaging the newspapers.
