OFFSET LITHO Meaning and
Definition
-
Offset litho refers to a widely used method of commercial printing that utilizes a flat plate and a rubber blanket to transfer ink onto a desired printing surface. The term "offset" originates from the process of the ink being transferred from the plate to the blanket before ultimately being applied to the final medium, such as paper or cardstock.
The offset litho process involves several key steps. First, an original image or design is created on a plate, which is typically made of aluminum or a similar material. This plate is then dampened with water, with the non-printing areas attracting the water and repelling the ink.
Next, the plate is coated with ink, which is applied by the plate's surface through either manual or computer-controlled methods. The ink adheres only to the areas that have not been dampened, forming the desired image. The rubber blanket then makes contact with the inked plate, transferring the image onto its surface.
Finally, the rubber blanket presses against the final printing medium, creating a high-quality, precise reproduction of the original image. Offset litho is known for its ability to produce vibrant colors, sharp details, and consistent results, making it a popular choice for various forms of commercial printing, including magazines, brochures, and packaging materials.
Overall, offset litho is a versatile and efficient printing technique that combines the use of specialized plates, ink, and rubber blankets to create high-quality reproductions of original images on various printing mediums.

Etymology of OFFSET LITHO
The word "offset litho" is a combination of two terms: "offset" and "litho".
- "Offset" refers to the printing process known as offset printing. It originated from the verb "to set off", which means to transfer an image or text onto a different surface. This process involves transferring an inked image or text from a printing plate to a rubber blanket, and then onto the final printing surface (usually paper). The term "offset" emphasizes the fact that the image or text is first transferred to an intermediate surface before being printed.
- "Litho" is derived from the word "lithography". Lithography is a printmaking technique invented in the late 18th century, in which an image is created on a smooth surface (usually a stone or metal plate) using oil-based materials or wax crayons.
