Offset printing is a printing method that uses a printing plate to transfer an image onto a substrate. It is a popular printing method for producing high-quality prints in large quantities.
Offset printing works by first creating a printing plate from an image or text. The printing plate is then we use it to transfer the image or text onto a substrate. The substrate is then heated and a layer of ink is applied to the printing plate. Then this ink is transferring to the substrate and the image or text is printed.
The main advantage of offset printing is that it produces high-quality prints at a lower cost than other printing methods. Additionally, offset printing is faster than other printing methods and can produce prints in large quantities.
What is Offset Printing?
Offset printing is a process which we use to print from a metal plate,
then coated with ink. The ink adheres to the non-image areas of the plate, and then it is transferred to a rubber blanket.
The plate is inked again and then passed under pressure over the printing surface.
In 1875, William Bullock invented the first press of history of offset printing . This allowed for more efficient printing of books and newspapers. In 1887, Thomas Edison invented the electric power for offset lithography presses which allowed faster production rates.
The first use of offset lithography was in 1893 by August Fiedler on behalf of Aloys Senefelder in Vienna.
How does it work?
Offset printing works by first creating a printing plate from an image or text. The image or text is then printed onto a printing plate, which is then used to transfer the image or text onto a substrate.
The printing plate is first coated with a layer of ink. The substrate is then heated and the ink is transferred to the substrate. The ink is then absorbed into the substrate and the image or text is printed.
The printing process is repeated for each color that is used. After the printing is complete, the substrate is then cut and folded according to the desired specifications.
The Importance of “Offset” or “Digital” Printing
Offset printing offers several advantages over other printing methods. It is a cost-effective printing method that produces high-quality prints. Additionally, offset printing is faster than other printing methods and can produce prints in large quantities.
Offset printing is also versatile and can be used to print on a variety of substrates, including paper, plastic, and metal. It is also capable of printing in multiple colors, making it an ideal choice for full-color printing.
Finally, offset printing is more durable than other printing methods and can produce prints that will last for years.
