What is the Offset Process of Printing?

Offset is the traditional process of printing that was widely used before the advent of digital printing. Offset process is still very much in use although digital has also created its own niche.

Offset printing process involves the use of plates to transfer images on to the print surface. In this technology, an inked image is ‘offset’ or transferred onto the plate and from there to a rubber blanket. From the blanket, the image is transferred to the paper or print area. Offset technology relies on the lithographic technique that uses the repulsion of water and oil to create the actual image

Advantages  

Offset printing Sydney is a low-cost approach for printing in large volumes. In fact, the production cost by using offset technology reduces as the volume of print increases.

Offset technology also offers more options for finishing and is best suited for prints having solid colour blocks. With offset technology, you can expect sharper and more vibrant images and it can be used on different surfaces including plastic, leather or metal.

Disadvantages

The prime disadvantage of offset technology is that it becomes prohibitively expensive for small print runs. For example, you would need to print at least 1000 copies of an A4 print in order to make it cost-effective through offset process.

Another major disadvantage is that you cannot make changes in the print once the master plate has been created. Subsequent prints will be based on this master plate and any changes will require a new plate and more expense. Offset process is also time-consuming and you need to maintain a large printing setup.
