1. Type Definition Advantage Disadvantage Example
Etching(hand) 1. etching, a metal plate is
covered with a waxy ground
which is resistantto acid.
The artistthen scratches off
the ground with a
pointed etching needle where
he or she wants a lineto
appear in the finished piece,
so exposingthe bare metal.
Some advantages of dry
etching are its capability of
automation and reduced
material consumption. Dry
etching costs less to
dispose of the products
Is that they do not have high
anisotropy becausereacting
species can reactin any
direction and can enter from
beneath the masking
material.
Anisotropy is when the
etching exclusively occurs in
one direction.
Woodcut(hand) An artistcarves an imageinto
the surfaceof a block of
wood—typically with
gouges—leaving
the printing parts level with
the surfacewhileremoving
the non-printing parts

Letterpress(mechanical) Letterpress printingis a
technique of relief printing
usinga printingpress,a
process by which many copies
are produced by repeated
directimpression of an inked,
raised surfaceagainstsheets
or a continuous roll of paper
its hand-crafted look and feel;
giving character and charmto
a variety of printed product
High-quality and one-of-a-kind
craftsmanship.Becausetext
and images areactually
impressed into paper
Color can be applied in
letterpress printing,but each
color has to dry before the
next color is applied froma
different set of letters placed
on the press.
letterpress is also slow
because you need to wait for
the ink to dry
2. Laser Printing(Digital) printer that provides high-
resolution images.
A laser produces an image on
a rotating drum, which is then
rolled through a type of ink
that transfers to the places
illuminated by thelaser.
Colour printing is possible
Print quality is good
Noiseless
Printing speed is high
Most models are relatively
light weight and compact
so they don't take up too
much space on the desk
Not be the printer of
choice for everyone, Due
to the cost of ink, running
an inkjet printer over time
is a more expensive than a
laser printer.
Prints emerge from the
printer slightly wet and
may need time to dry.
Printing is slower and
therefore inkjets aren't
designed for high volume
printing
Inkjet(Digital) a type of computer
printing that recreates a
digital image by
propelling droplets of ink
onto paper, plastic, or
other substrates.
Low cost
2) High quality of
output, capable of
printing fine and smooth
details
3) Capable of printing in
vivid color, good for
printing pictures
4) Easy to use
5) Reasonably fast
6) Quieter than dot
matrix printer
7) No warm up time
Print head is less
durable, prone to
clogging and damage
2) Expensive
replacement ink
cartridges
3) Not good for high
volume printing
4) Printing speed is
not as fast as laser
printers
5) Ink bleeding, ink
carried sideways
causing blurred effects
on some papers
