Gravure printing technique
is used for long run printing with sharper, fine and clear
images. It is generally used for high-volume printing of packaging,
wallpaper, and giftwraps using fast-drying inks. Although
not widely used, gravure printing also finds application in
printing magazines, greeting cards, and high-volume advertising
print campaigns
Process
Gravure printing Process is a form of intaglio printing. The
technique uses a depressed or sunken surface for formation
of the image. The image area consists of honey comb shaped
cells that are etched or engraved into a copper cylinder.
The unetched area of the cylinder represents the non-image
or unprinted areas. The cylinder generally rotates in a bath
of ink called the ink pan. With the turning of cylinder, extra
ink gets wiped off the cylinder due to a steel doctor blade.
Image is formed due to the direct transfer of the ink to the
substrate (paper or any other material) while it passes between
the plate cylinder and the impression cylinder.
This method allows multi color printing at
very high speeds. Most machines are equipped with in-line
die cutting, sheeting and perforating mechanism and have a
high performance drying system. The machines allow for quick
changeover features and sleeve engraving to make the printing
economical.
