FAQs Related to Newspapers Printing Machines

Which machine is used to print newspapers?

A web offset printing machine is used for newspaper printing. It is designed in both vertical and horizontal configurations. This type of machine is also referred to as a reel-fed offset printing machine. Additionally, newspapers can also be printed on sheet-fed offset printing machines.

What is the name of the machine that prints books and newspapers?

The machine used for printing books and newspapers is called a web offset printing machine, and it comes in three models: STAR 30, STAR 16, and NEWSPRINTS.

What is the printing process of newspapers?

Newspaper printing primarily utilises offset printing technology. This process involves a 4-cylinder printing system for simultaneous front and back printing. Offset printing relies on the combination of plates and blankets. Dampening and inking systems are employed to clean the plates and apply ink. The plates are made of aluminium with photosensitive properties for text exposure, while the blankets are rubber-based and carry a reverse image that is transferred onto paper in a straight manner.

What is the production capacity of the Newspaper Printing Machine?

The Newspaper Printing Machine is designed for high-speed production. It is available in three speed ranges: STAR 30 is capable of producing 30,000 newspapers per hour, STAR 16 has a speed of 16,000 newspapers per hour, and NEWSPRINTS can produce 36,000 newspapers per hour.

Can the machine handle different types of paper materials?

Web offset printing machines can handle both newsprints and writing paper. Writing papers typically have a GSM (Grams per Square Meter) of less than 100 GSM, while newsprints have a GSM of less than 55 GSM.

Is training provided for Newspaper Printing Machine operation?

Upon request, training can be provided. Skilled operators are also readily available across India. During installation and commissioning, our engineers provide basic training related to machine operation and maintenance.

What safety features are incorporated in the Newspaper Printing Machine?

The basic design of the web offset printing machine includes enclosures, guards, and covers for all moving components to ensure operator safety. When the machine is started, a hooter sounds for a few minutes to alert everyone to stay away. Tower lights indicate the machine status, whether it is running, stopped, or in a setup process.

Are spare parts readily available?

There are two types of spare parts: consumables and mechanical components that may need frequent replacement. The machine is supplied with standard spare parts and a toolkit, while consumables are arranged by clients. Spare parts are readily available in our stock.

Which paper is best for Newspaper Printing Machine?

Traditionally, newspaper printing commonly uses 45 GSM salmon newsprints, 55 GSM improved newsprints, and 70 GSM improved newsprints.
