Letterpress is the oldest and fastest diminishing method used today. Developed centuries ago by the Chinese it is still used to print newspapers, labels, etc. Its quality, however, is not that of the other main processes and tends to print mid to low quality.
Flexography is a newer printing process developed during the mid 1900's. Flexography has found wide application in printing for food packaging with plastics and non-absorbent stock. It is also used to print envelopes, newspapers, pressure sensitive labels, etc.
Gravure is another old printing process used to print packaging, magazines, wallpaper, gift wrap, etc. The major advantage of Gravure is that it can print very long runs due to its configuration. Sear advertising, for example, can count into the millions of printed pieces. Unlike offset, Gravure uses a metal printing cylinder can handle these types of long jobs without wearing out the printing cylinder. Money and postage stamps are also printed using a form of Gravure (Intaglio).
