Offset printing technology

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. 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.
