What Is Offset Printing

What is offset printing?

Offset printing, also known as offset lithography, litho or lithographic printing, is a high quality printing process typically used for large volume print runs.

Offset printing works by applying ink to a pre-prepared aluminum plate, then transferring the ink to paper stock using print machines to create the desired impression. It is this indirect method of transferring ink to paper that gives offset printing its name.

Images are typically produced through a four colour process. Cyan, Magenta, Yellow and Black (or Key), known collectively as CMYK, are combined separately until the full colour image is produced.

Where required, additional printing plates can also be added, allowing for the addition of customised inks such as metallic, UV and Pantone colours.

Despite the continued development of digital print, offset printing is still regarded as the highest quality printing process available.
