WHAT IS INTAGLIO?
In contrast to relief printing, the image area lies recessed beneath the non-printing surface.
The sunken areas, which hold the printing ink, are called cells. The raised elements are known as land areas. After the ink has been applied to the printing cylinder, the excess ink is scraped off the surface with a doctor blade before printing. The ink, which now only sits in the depressions, is transferred through contact pressure and the adhesive power (adhesion) working between the paper and the ink. Gravure, recess printing and offset gravure are all types of intaglio printing. Today, for economic reasons, intaglio printing is mainly used for high-volume print jobs.
The largest market segments for intaglio printing are newspapers and catalogues, and packaging (rotogravure), and banknotes and decorative printing.
