2. What is 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.
3. If you don’t understand
complicated words –
(Like me)
The
printer recreates an image from the computer
onto a solid surface such as paper, acetate etc.
This means that the ink is squirted out of the
cartridges on to the paper.
This also means that the quality is not brilliant
- In fact, the quality is very pixelated.
4. How do they work?
This
can be done using one of two
methods.
5.
6. Thermal Inkjet Process.
The
print cartridges contain a series of tiny
chambers, each containing a heater.
To eject a droplet from each chamber, a
pulse of current is passed through the
heating element causing a rapid
vaporization of the ink in the chamber to
form a bubble, which causes a large
pressure increase, propelling a droplet of
ink onto the paper (hence Canon's trade
name of Bubble Jet). – (Wikipedia)
7. Piezoelectric Material
Uses
an electrical pulse in an ink-filled
chamber behind each nozzle instead of a
heating element.
When a voltage is applied, the
piezoelectric material changes
shape, which generates a pressure pulse
in the fluid forcing a droplet of ink from
the nozzle.
11. What are they used for?
They
are the most common consumer
form of printer as they are cheap and
easy to find.
Of course, they are used for printing, but if
you want to print photos – this is not the
best choice.
