| In a web press, the printing plates are wrapped around revolving cylinders called drums. This press uses the rotary relief process, which has been the most common printing method for mass-producing newspapers, books, and magazines for many years. Here, an operator adjusts a plate before printing is resumed. Adjustments are made based on sample copies that are printed to check for consistent color and impression, a process called makeready. When the press is started, paper will pass between these two rollers, receiving print on both sides simultaneously. |
