Foreword: Printing press is one of the most commonly used equipment in modern society. Using printing presses, text and images can be printed in large quantities, so that information and knowledge can be continuously disseminated. The web printing press, as the most important one, also plays a very important role. The following article will explain the relevant knowledge of the rotary printing press for everyone.


Rotary printing press is a kind of large-scale printing equipment, and printing presses are generally very large. But in contrast, the workload of a rotary printing machine is quite astonishing. A large rotary printing machine can print 100,000 to 120,000 characters per minute on average. The most important part of the rotary printing machine is the rotary system of the rotary printing machine. The ink is printed on the paper through the continuous rolling of the rotary drum, so that the text that needs to be printed can be printed. Let's take a look at the working principle of the rotary press?


The most important part of a rotary printing machine is its plate cylinder. A large amount of ink is often added to the peripheral printing seat of the plate cylinder. If you need to print color content, you need to add the corresponding color ink to the peripheral printing seat of the plate cylinder. . The plate cylinder keeps rotating, it will print all the ink on the paper, so that the rotary printing machine can complete the printing task. So, how to pass the text information we need to print to the rotary printing machine so that the rotary printing machine prints the content we need?


After finishing the typesetting of the text to be printed, add the typeset content to the rotary printing machine, and the rotary printing machine can print according to the typeset text information. Of course, this is the most commonly used method, but its efficiency Is very limited. Now most of the rotary printing is through the computer to give instructions. The text information is transmitted to the computer that controls the work of the rotary printing machine, and the printing instructions are issued to the rotary printing machine through the computer. When the rotating wheel of the printing press is continuously rolling, the rotary printing press can perform printing tasks without interruption. This can effectively improve the working efficiency of the printing press.


When using a rotary printing machine, you need to pay attention to the following items. When using a rotary printing machine, you need to divide the normal printing and color printing into two printing machines to complete. Can not let the same printing machine complete the task of color printing and ordinary printing at the same time, because this may cause printing errors in the printing machine. The runner of the rotary printing machine needs to be overhauled regularly to prevent malfunctions during the printing process and cause unnecessary losses. Rotary printing presses should be cleaned regularly to prevent the subsequent printing tasks from affecting the subsequent printing tasks and reducing the quality of printing due to excessive residual ink.
