What Is Offset Printing?

Offset printing is the most commonly used printing method today. Over 40% of all print jobs are carried out using offset printing. The main advantage of offset printing is the ability to achieve consistent image quality across small, medium and high volume of printing requirements. These all achievement’s are not possible without offset printing press in Mumbai.

Offset printing is the most commonly used method today, and has many advantages over other forms of printing, especially when we need high and consistent image quality.

Color wheel:

This is a process used for printing on a flat surface, using plates. An image is transferred to a offset plate which is chemically treated so that only image areas (such as type, colors, shapes and other elements) will accept ink. Water and ink is applied to the plate. Because of the chemical treatment, ink only “sticks” to the image areas, which reject the water. Areas without images reject the ink. The images with ink are transported then from the plate to the surface of blanket. The task of printing blankets that are made of special multi-layer rubber is to convey the image or illustration to the paper and this is repeating on every cardboard that passes through the printing machine.  When we print full color job the cardboard is overprinted four times on four separate printing units with different colors.

A unique characteristic of offset printing is that the image and non-image areas are on the same surface level. The printing method uses the chemical fact that oil and water do not mix to print from a single surface level. In fact, offset printing acquired this method from lithography and thus it is often referred to as litho offset printing as well.

Offset processes are primarily of two types:

·         Sheet-fed Offset Printing Press: In this kind of offset press the printing is carried out on single sheets of paper as they are fed to the press one at a time.

·         Web-fed Offset Printing Press: In this kind of offset press the printing is carried out on a single, continuous sheet of paper fed from a large roll. The sheet is then cut into individual sheets of desired sizes.
