Offset Printing: The Workhorse of Printing Plants

Offset printing is the most widely used printing technique in printing plants. Its versatility, cost-effectiveness, and ability to produce high-quality prints make it the go-to choice for various applications. Let’s explore the key components and steps involved in the offset printing process:

Plate Making

Offset printing starts with plate making. The design from the prepress stage is transferred onto printing plates, typically made of aluminum or polyester. The plates undergo a process called “exposure,” where they are exposed to UV light or lasers to create the image. The plates are then mounted onto the printing press.

Ink Application

Once the plates are in place, the ink application process begins. Ink rollers transfer the ink onto the plates, where the image areas attract the ink, while the non-image areas repel it. This process is known as the “offset” principle, where the ink is first transferred from the plates onto a rubber blanket cylinder and then onto the paper. This indirect transfer allows for precise and consistent ink application.

Image Transfer

After the ink is applied to the paper, it undergoes the image transfer process. The paper passes through the printing press between the blanket cylinder and the impression cylinder. The blanket cylinder presses the paper against the plate, transferring the inked image onto the paper. This process is repeated for each color in the design, as offset printing can utilize multiple colors in a single print run.

Drying and Finishing

Once the image transfer is complete, the printed sheets go through a drying process. The ink needs to dry completely before any finishing operations can be carried out. Drying can be achieved through evaporation, heat, or a combination of both, depending on the ink type and printing conditions. After drying, the printed sheets undergo post-press operations, such as cutting, folding, and binding, to give them their final form.

The offset printing process offers excellent print quality, color accuracy, and cost-efficiency, making it the workhorse of printing plants for various print materials.
