Litho printing, also known as offset printing, is a popular printing technique used by businesses and individuals alike to produce high-quality printed materials. It offers a cost-effective solution for large print runs while maintaining exceptional print quality that is suitable for a wide range of applications. In this article, we will delve into what litho printing is, how it works, its advantages, and some common applications.
What is litho printing?
Litho printing is a printing process that involves transferring ink from a plate onto a rubber blanket, which then transfers the ink onto the printing surface. This indirect method of printing is called offset printing because the image is first transferred to a rubber blanket before being applied to the final printing surface, usually paper.
The name “litho” comes from the use of a “lithographic limestone” plate, which was historically used in the process. Today, litho printing plates are typically made of aluminum or polyester, which are more durable and easier to work with. The process is based on the principle that oil and water do not mix. The image on the plate is treated so that ink adheres only to the image area, while the non-image areas repel the ink. This creates a sharp and clean print.
How does litho printing work?
Litho printing involves several steps to produce the final printed material. The process begins with the creation of a printing plate that carries the image to be printed. This is typically done using a photographic process that transfers the image onto the plate. The plate is then mounted onto the printing press.
The press itself consists of several rollers that apply ink to the plate. The inked image is then transferred to a rubber blanket before finally being pressed onto the paper or other printing surface. This method of printing allows for consistent, high-quality prints with sharp and detailed images.
