In this article we are going to discuss the two most popular printing techniques. Offset lithography method and digital printing. There are many other printing techniques a swell like engraving, laser printing, screen, thermography, flex printing etc. We are comparing offset and digital printing because they are the most widely used and common printing techniques.

It is then transmitted from the metal plates to rubber cylinders. The rubber cylinders then offset the matter onto the desired surface. The image that has to be printed uses ink from the fitted ink rollers and the areas that don’t required to printed draws water to it making sure those areas are ink free. Compared to the mechanics of offset printing, digital printing is much simpler. It eliminates the plates and rubber cylinders. The material that needs to be printed is accessed directly from the computer and printed like a copy. (continue reading…)
