Web Offset Printing Versus Digital Printing

The printing industry, just like others, has been adopting new processes and equipment over the years with the advent of newer technology. It is therefore now possible to use a variety of printing techniques for printing on different surfaces, in different quantities and for different purposes. However, in modern times, there are two principal printing techniques which are the most popular in commercial operations. Businesses have to choose between them, and this is an important decision. Choosing the printing technique for a particular printing assignment will lead to superior efficiency and better results. Besides, it will bring about better customer satisfaction and adherence to timelines.

Knowing the difference between the two technique processes is helpful. Web offset printing has a much longer history, since it has evolved from the original offset press printing which dates back to over a century ago. This conventional form of printing has remained almost true to its original process, except that the use of computers now saves a great deal of precious time. The process follows a path of computer-to-plate-to rubber blanket-to printing surface. Digital printing, on the other hand, is a much newer technique. The main difference is that it simply removes the numerous steps in image transfer. Instead, ink is applied in a single pass from an ink head. It is in fact quite similar to home or office-use inkjet printers.

Here's a look at some of the significant distinctions between the two techniques. Depending on the specific need of the assignment, the printing method may be chosen.
