The Offset Printing Process: How it works

Comments · 497 Views

Offset printing is one of, if not, the most popular printing technique across a range of different industries.

 

What is offset printing? In web offset printing, rolls of paper are fed continuously through the press. This is different from sheet-fed printing where individual strips are pre-cut before being sent to the press. There are two types of offset web printing:


Heatset - Once the paper is printed, the ink is dried by running the printed paper through an oven. This process is used in magazines, catalogs and other high quality printed materials.
Coldset - During this process the ink is gradually dried by evaporation and absorption. Commonly used for newspapers, coldset printing is one of the most cost-effective printing formats.

What is Offset Printing?
Offset printing or offset lithography is a printing technique that transfers ink from a plate onto a rubber roller (or blanket) and then onto a variety of substrates to create high quality images and designs.

Typically used for mass production. B. For printing large volumes of newspapers, brochures, stationery, magazines and of course boxes.
One of the most commonly used printing options due to its high quality output and consistent results.

Types of Offset Printing
Web Offset Printing
Web offset printing is primarily used for newspaper and box printing.

In this process, roll paper is continuously fed into the press and can produce over 5,000 prints.

Next, cut the paper (also part of the press) to make identical sheets.
The
rotary press can produce more than 3,000 sheets per minute he. This equates to approximately 80,000 identical sheets per hour.

This option is ideal for companies that need to produce large quantities of products quickly to meet tight deadlines.
Sheetfed offset printing In contrast to
web printing, sheetfed offset printing produces less output because the sheets are fed individually.

Still considered a fast print option compared to other prints available.
The
sheetfed can print up to 12,000 to 24,000 sheets per hour.

Years of modernization have also increased the speed of sheetfed printing, allowing it to perform functions similar to those of a web press.
