| If
you are using an inkjet cartridge then you may be having this
question in your mind…
How many colours can an inkjet printer can
produce?
Like most print processes, you only have
a limited selection of inks to use. However, full colour can
be derived from three primary colours, just like a monitor.
For monitors, these colours are Red, Green, and Blue because
monitors emit light resulting in an additive colour process.
Inks, on other hand, absorb light.
The resulting inks should then be cyan (blue+green
or -red), magenta (red+blue or -green), and yellow (red+green
or -blue).
Also, another question that could be lurking
in the corner of your mind can be following…
Why separate inkjet cartridge is used for
Black ink and all other colours may have same cartridge?
The fact is that the colours used in common
inkjet printers are not really capable of producing true full
spectrum photo realistic quality results since they are red
(not magenta), blue (not cyan), and yellow. These colours
are optimized for nice saturated primary colour when used
independently.
In addition, the combination of the three
primary colours should be capable of being combined to produce
black but due to incorrect optimization and the pigments used,
this black could be somewhat muddy and brown. Therefore, a
separate black ink cartridge is normally used for black printing.
There are some changes that you can do to
change your print patter and quality.
For example, if you can vary the drop size, you can change
the drop spread on the paper. This can be done by firing bigger
slugs of ink, or multiple drops at the same position.
You can figure the ink will either spread
and make a bigger drop, or stay the same size and become denser.
Depending on the resolution you want these could both improve
colour density. This depends on two key components, the ink
and the paper.
However, there could be some issue while spraying
down multiple drops on paper, like if you do a large block
the paper will curl up and the overall image becomes worse.
The solution is to use a high quality paper.
Another problem that could arise is speed.
Spraying two drops in the exact same place is difficult, unless
the head is stationary but that is not good either. You may
notice that most inkjet printers with high resolution mode
do a number of passes over the same place. This does allow
dithering and other techniques for resolution or colour enhancement.
They usually only print while are going in one direction for
improved mechanical control.
Inks are a problem too. They can dry at different
times because of the different dyes used, or they may not
mix how you expect if you place two colours on top of each
other. To get equilibrium of surface tension, drying time,
viscosity, colour and stability are not an easy. However,
the water based inks are improving. But there are some that
does not run if they get wet after drying on the paper.
