So, what exactly is litho printing?
Litho printing is a printing technique based on the principle that oil and water do not mix The process involves transferring an image or text from a plate onto a rubber blanket, which in turn is then offset onto the printing surface, such as paper or cardstock This method allows for large volumes of prints to be produced quickly and efficiently, making it a popular choice for magazines, brochures, posters, and other printed materials.
How does litho printing work?
The first step in litho printing is creating a printing plate This plate is made of a metal or paper base coated with a photosensitive emulsion The image or text to be printed is transferred onto the plate using a photographic process The areas of the plate that are exposed to light become hydrophilic, attracting water-based ink, while the non-image areas remain oleophilic, attracting oil-based ink.
Next, the plate is mounted onto a printing press, where it is dampened with water and inked up The ink adheres to the image areas on the plate, while the water repels the ink from the non-image areas The plate then transfers the image onto a rubber blanket, which in turn offsets the image onto the printing surface.
What are the benefits of litho printing?
