3. SCREEN PRINTING ETCHING
Screen printing is a printing technique that
uses a woven mesh to support an ink-blocking
stencil to receive a desired image.
The attached stencil forms open areas of
mesh that transfer ink or other printable
materials which can be pressed through the
mesh as a sharp-edged image onto a
substrate. Screen printing is also a stencil
method of print making in which a design is
imposed on a screen of polyester or other
fine mesh, with blank areas coated with an
impermeable substance.
Etching is the process of using strong acid
or mordant to cut into the unprotected parts
of a metal surface to create a design
in intaglio in the metal. Linocut is
a printmaking technique, a variant
of woodcut in which a sheet of linoleum is
used for the relief surface. A design is cut
into the linoleum surface with a sharp knife,
V-shaped chisel or gouge,
4. WOOD CUT
LITHOGRAPHY
Woodcut-A relief printing artistic
technique in printmaking in which an
image is carved into the surface of a
block of wood, with the printing parts
remaining level with the surface Multiple
colours can be printed by keying the
paper to a frame around the woodblocks.
The art of carving the woodcut can be
called "xylography", but this is rarely used
in English for images alone,
Lithography - Is a method
of printing originally based on the principle
that oil and water do not mix. Printing is
from a stone (limestone) or a metal
plate with a smooth surface. It was
invented in 1796 by German author and
actor Alois Senefelder as a cheap
method of publishing theatrical works.
In modern lithography, the image is
made of a polymer coating applied to
a flexible aluminum plate. The image
can be printed directly from the plate.
6. LETTERPRESS PRINTING GRAVURE
Letterpress printing is a technique of relief
printing using a printing press. A worker
composes and locks movable type into the
bed of a press, inks it, and presses paper
against it to transfer the ink from the type
which creates an impression on the paper. is

was the normal form of printing text from its
invention by Johannes Gutenberg in the mid-
15th century until the 19th century
and remained in wide use for books and
other uses until the second half of the 20th
century.
Rotogravure (Roto or Gravure for short)
is a type of intaglio printing process,
which involves engraving the image
onto an image carrier. In gravure
printing, the image is engraved onto
a cylinder because, like offset

7. SCREEN PROCESS
Screen printing is a printing technique
that uses a woven mesh to support an
ink-blocking stencil to receive a
desired image. The attached stencil
forms open areas of mesh that transfer
ink or other printable materials which
can be pressed through the mesh as a
sharp-edged image onto a substrate.
9. PHOTOCOPYING LASER PRINTING
A photocopier is a machine that
makes paper copies of documents and
other visual images quickly and
cheaply. Most current photocopiers use
a technology called xerography, a dry
process that uses electrostatic charges
on a light sensitive photoreceptor to
first attract and then transfer toner
particles (a powder) onto paper in the
form of an image.
Laser printing is an electrostatic digital
printing process that rapidly produces
high quality text and graphics by
passing a laser beam over a charged
drum to define a differentially charged
image. The drum then selectively
collects charged toner and transfers
the image to paper, which is then
heated to permanently fix the image.

Desktop publishing is the creation of
documents using page layout skills on
a personal computer. Desktop
publishing software can generate
layouts and produce typographic
quality text and images comparable to
traditional typography and printing.
11. INKJET PRINTING
.
Inkjet printing is a type of computer
printing that creates a digital image by
propelling droplets of ink onto paper,
plastic, or other substrates. Inkjet
printers are the most commonly used
type of printer
