The Offset printing process is when the image is transferred from a metal plate attached to a rubber roller which is then applied to the printing medium. The rubber rollers (or rubber blankets) conform to the printing surface which gives a very sharp and detailed final image.
Offset printing gives a very consistent high-quality result and can print all Pantone and PMS color systems. The offset printing presses require a lengthy setup of cylinders and plates as well as a preliminary printing run to allow for quality control. Due to the steps involved in setup and test runs, offset printing is more cost-effective in large scale printing runs – common products include books, magazines, catalogs and press. Offset printing can be applied to a wide range of printing surfaces such as plastic, metal, cloth and even wood.
