WHAT IS OFFSET lithograph?

The production process is a photo mechanical technique. The original artwork or transparency is scanned and from the scanned image the four separations (or film) are output. From the separations, the image is etched onto photo-sensitive metal plates. The plates are loaded on to the press for printing. The reproductions are printed with the highest UV rated inks available on 100% acid-free paper.
