The gravure process has become established as a major part of the printing industry. At the time of its invention, at the beginning of the twentieth century, it offered the means of high quality reproduction on paper coupled with high press speeds, which in due course gave it an advantage over the established litho and letterpress processes, especially for publication printing. In later years the process was to prove ideally suited for printing the rapidly developing non-porous substrates, principally coated and uncoated cellulosic films and aluminium foils. As the era of the plastic films emerged, flexographic printing also developed and combined with gravure to become the major sources of printed flexible packaging. Gravure printing has many other areas of application, including paper and board packaging materials for confectionery, foodstuffs and the tobacco industry. It gained favour in the printing of cigarette cartons because of its lower production costs. It also offered superior metallic golds when required. The lower costs can be attributed to the use of the in-line cutting and creasing operation which produces finished blanks from the reel. This is made possible by the drying characteristics of gravure inks. There are many non-packaging applications where the gravure process has been adopted. Postage stamps, football coupons and catalogue printing are typical examples.
