The rotogravure is a form printing process referred
to as intaglio printing process .This process involves engraving an
image into an image carrier. The process uses rotary printing press
where the image to be printed is engraved onto a cylinder. This process
is used for commercial printing of magazines, cardboards aluminum,
foil paper and also in product packaging.
From the above definition of rotogravure printing, we
can define the rotogravure printing machine as the machine used in
the printing process described above.
The modern machine uses a printing cylinder with tiny
cells that have been engraved on it. The cells have the ability to
retain ink, the pattern and the size that finally reflect the final
image of the product.
High speed rotogravure printing machine: This is a
fast speed kind of printing machine. The bigger number of rotogravure
machines print rolls as opposed to sheets of paper. The machine is the
fastest in speed and also the widest in the printing industry. For
the maximum level of efficiency, this machine operate at high speeds
producing very big diameters and wide rolls.
Applications of Rotogravure Printing Machine:
The roto printing machine is popular and mostly used
in the fine arts and photography reproduction sectors because of its
high density range in printing.
The printing process is also commonly used in food
manufacturing and the packaging sectors. The gravure printing machine
can print a wide range of substrates some of which involve polyester,
polythene and BOPP among others. The rotogravure machine is most
popular in this sector because of its ability to print well on thin
films such as nylon and polyester.
The printing process is also applied in manufacture
of wall covers and transfer printing. The process has further
applications in the security printing, the tobacco sector and
generally used the industrial sector.
Important features of the machine
· The rotogravure printing machine is characterized
by a single printing unit for each color mostly Cyan, Magenta, Yellow,
and Key which is the common printing reference of the color black.
The number of units however mainly depends on the color you wish for
the final image.
· High density range: the rotogravure printing
machine is capable of transferring much more ink to the paper than the
typical printing processes. This feature has made the machine popular
in fine art, and photography reproduction
· The rotogravure printing machine allowed the
ability to transfer ink consistently over a big range of densities at
high speeds. This makes it suitable for applications that need high
quality images, for example packaging, publishing and decorative
printing.
· Long service life: The machine can print cylinders
that are long lasting. They last even through large volume runs
without the risk of them getting worn out.
· Another characteristic feature of the machine is
its low per unit costs running especially in cases with high volume
production.
· Good heat conduction.
The sectors where the machine is applicable
The printing machine is used in the following sectors
· In printing magazines that are long run and exceed over a million copies.
· The mail order catalogs also use this printing machine.
· Packaging for consumers
· In furniture making where quality and consistence is privy the printing machine is used to print wallpapers and laminates.
· Newspaper adds inserts, also frequently use this printing machine.

The rotogravure printing machine is well designed to
produce high quality images. The cells in the cylinder that allow
consistent flow of ink and the engraving of the image on the cylinder
all contribute to the high quality of the final images produced by
this machine. The printing technique used by the machine is used in
the manufacturing and the industrial sectors on large scale. It is
therefore among the best printing machines that can be used for high
volume production of quality products and images..
