   Digital Printing vs. the Traditional Method in Photography
Author: John Sollars
Over the past years, technology has been continuously evolving
and it has brought about improved graphics, artworks and
printing. Newer breakthroughs in technology have also made
printing affordable and easy to use.
For photographers too, printing has been made very easy and
consultative. More photographers have switched from the old
style to the modern enlarged printing with the use of digital
inkjet printers.
With the modern use of digital cameras now taking into effect to
make perfect digital shots, photographers no longer have to go
through the process of scanning of the negatives from the
pictures taken This is the one of the main reasons more
photographers have switched over to the digital age technology.
Digital image printing is developed in corresponding software
such as PhotoShop, CorelDraw and may other types of software.
However, among them all, Photoshop is the most commonly used
software application to meet the demands of clearer and precise
digital prints. In fact, it has now become difficult for
photographers to sell the equipment formerly used in the
darkroom.
With the growth of printing technology, new issues have also
sprung up, such as whether digital printing is really as
aesthetic and long lasting. Critics wonder if digital printing
can contain the same level of output as that of traditional
images. For others, printing in inkjet printers is akin to
imitating the original as they are printed with the use of ink,
while the traditional method contained natural mixture for
photography purposes. Nevertheless, even with the advancement in
digital photo printing, a number of people still appreciate the
old technique of printing.
In case you?re wondering about when the debate of digital
printing over traditional was sparked off, it started with
doubts over the long-lasting effect of inkjet prints over
emulsion printouts. Critics have questioned if inkjet prints can
endure the exposure longer and maintain their quality. However,
some have proven that the traditional prints have not lasted as
long and have slowly been fading in time as well. This
observation strengthens the belief that no image can withstand
exposure for a long period of time yet. Given that the
developments in digital technology are ever increasing,
questions and issues regarding its performance have been
lessened for it has played its role well till date.
Inkjet prints have greatly contributed to giving an eventual
effect in the uniqueness of images. The technique of inkjet
printers involves spraying a number of tiny dots onto the paper,
making the image sharper and more defined. This is perhaps a
simple example of how the new printing technology has played its
part of contributing to creativity and has now defined its own
field of artwork.
The acceptance of inkjet prints has been quite unpredictable so
far. In some exhibitions and art galleries, inkjet print designs
are easily allowed, whereas some follow strict rules against the
display of such prints. Alternatively, some designers still
prefer the traditional emulsion prints to be part of their
artworks. For those who rely on digital printing, the choice is
based on practicality and reverting to the traditional technique
is not longer financially viable. Digital printing has also made
enlarging of prints and images much easier than traditional
printing. It has been suggested that in time, when digital
printing will continue its rise in the world of technology, many
will make the switch over from the traditional method to the
digital one.
The use of digital printing requires refinement in art skills,
and accuracy and precision should be followed and maintained. To
enhance printing abilities, the aid of Photoshop, or similar
types of software can prove to be very useful for acquiring
spectacular prints.
Cyan And Magenta Explained
Moving on to ink cartridges used in printers, anybody who has
purchased these cartridges would know that there is no blue or
red ink. Cyan certainly looks blue and magenta definitely looks
red ? but have you ever wondered why they simply don?t call them
blue and red instead of cyan and magenta?
Here's the explanation ? both monitors and printers use
different ways to produce colour. While a monitor is a light
source, printers are light reflecting. The only common ground
between the two is something known as dithering. It is the
process of approximating a colour that cannot be displayed with
uniformly dispersed dots of other colours.
This technique assigns differing colour values to adjacent
pixels, thereby reducing the contrast between dots of different
colours or shades and generates a more flowing, natural
impression. When viewed from a distance, these colours seem to
blend into a single intermediate colour. Dithering is similar to
the half toning used in black-and-white publications to achieve
shades of grey.
Coming back to the discussion, both monitors and printers use
primary colours; however, a monitor uses primary additive
colours red, green and blue, while printers use the primary
subtractive colours cyan, magenta and yellow. In both cases, the
primary colours are dithered to form the entire colour spectrum.
Dithering breaks a colour pixel into an array of dots so that
each dot is either made up of one of the basic primary colours
or intentionally left blank to create white.
Cyan and magenta are in fact old printing terms for blue and
red, but since some form of differentiation is needed between
the additive and subtractive spectrum, cyan and magenta are here
to stay! John Sollars is the managing director of Solar
