Industry Segments |
|
|
|
The printing industry can be separated into four main segments and each must comply with
all of the general industry standards
(29 CFR 1910).
Lithography
|
Lithography is a planographic printing system
where the image and non-image areas are chemically differentiated with the image
area being oil receptive and non-image area water receptive. Ink film from the
lithographic plate is transferred to an intermediary surface called a blanket,
which, in turn, transfers the ink film to the substrate. Fountain solution is
applied to maintain the hydrophilic properties of the non-image area. Ink drying
is divided into heatset and non-heatset. Substrate can be fed into the press either
as individual sheets or from a continuous roll or web.

Flexography
|
Flexography
routinely prints jobs that we all have contact with on a daily basis in the
supermarket, at the warehouse store, at the shopping mall, and local newsstands.
This printing process uses a flexible printing plate with a raised
image mounted on a rotary cylinder. The liquid and fast-drying
ink is applied to the printing plate by way of a finely
engraved rotary cylinder, called an anilox roll. A flexo
press is equipped with one to twelve color stations and
can print on virtually any type of substrate, from corrugated
board to flexible plastic film or textiles and cloth fabrics.

Gravure
|
Gravure is
an intaglio printing process. Gravure is the simplest
of the major printing processes in terms of the number of ink
transfers and moving parts. An image carrier has the
image cut or etched below the surface of the non-image
area. On the gravure image carrier all the images are
screened, creating thousands of tiny cells. During printing,
the image carrier is immersed in fluid ink. As the image
carrier rotates, ink fills the tiny cells that cover
the surface of the cylinder. The surface of the cylinder
is wiped with a doctor blade, leaving the non-image area
clean while ink remains in the recessed cells. Substrate
is brought into contact with the image carrier with the
help of an impression roll. At the point of contact,
ink is drawn out of the cells onto the substrate by capillary
action and transferred (printed) on the substrate. The
substrate is passed through a dryer where the ink is dried.

Screen Printing
|
Screen printing is
a printing process in which printing ink, coating, or adhesive material is
passed through a taut web or fabric to which a refined form of stencil has
been applied. The stencil openings determine the form and dimensions
of the imprint.
