Art and Design A comprehensive guide for creative artists - Aaltodoc

For instance, in many situations packaging designs end
up as three dimensional designs. Thus, a design created to
serve as a wrapper is not likely to appear like the one meant
for a package.
Natarajan et al. (2009, 2-3) add, “Packaging has also been
described as complex, dynamic, scientific and artistic ... It is
constantly changing with regard to new materials, methods
and machinery resulting in better quality products which
open up new markets ... At the user level, the needed value
for the added function is different relating to the opinion
about waste accumulation, energy and use of scarce
resources.” We can conclude from this that, by designing a
wrappers we are literally making a package.
Computer aided printing
The main features of computer aided printing are
hardware and software. By software we mean computer
programs or applications used throughout operations.
Well as, by mentioning hardware we are referring to tools,
equipment and machinery. The most important thing about
computer-aided printing is high speed, ability to track the
work process and beautiful final designs.
Hastings (1986, 3) offers a rational explanation: “Before
using the advanced computer aided design applications
... you must at least be familiar with the basic ... operating
procedures such as clicking, dragging and selecting and
know what is meant by dialogue boxes, windows, icons,
menus and so on.” Undoubtedly, then, a creative graphic
designer who is planning to work with computer aided
printing is at a minimum expected to have necessary
computer knowledge. Kenly & Beach (2004, 74) assert,
“images on paper consist of patterns of cyan, magenta,
yellow and black dots: CMYK for printing.
This is how CMYK and RGB appear:
C Cyan Blue R Red
M Magenta Pink G Green
Y Yellow Yellow B Blue
K Black Black
RGB colours deal with light like; display
monitors, photo films and ink-jets
Colorants and toners create different colours by blocking,
or subtracting, different portions of the white light reflected
by the paper that they are deposited on.” Regardless of
the high speed and the good quality brought about by
computer aided printing. The process allows the operation
of printing direct from a computer to a digital printer or a
plate-making machine.
Black is regarded as the most important colour of CMYK
used by commercial printers—in the printing industry. To
the same extent, many office documents are usually printed
by using a desktop printer. While, “the two most common
types of printers today include laser printers and ink-jet
printers ... A laser jet type of printers forms images with
toner powder (ink powder) and ink-jet printers form images
with liquid ink” (Morley & Parker 2009; 173)
Clearly then, computer aided printing is supported by
technology and it is highly industrial. As you continue to
read about printing, you will discover very many new and
advanced methods as a result of new technology. Make
further consultations from people involved with computer
aided printing to learn more.
Methods of printing
A wide range of printing methods and techniques have
existed before. For instance, letterpress and offset printing
are among the many methods which belong to the
very distant past—of the common methods of printing.
Nonetheless, today printing can be done straight away
from a personal computer or a mobile phone to an all-large
format digital laser jet printer.
Let us briefly examine the three basic methods used during
printing:
a) Relief printing is a method of printing done on a
raised surface—and then, it is transferred on a paper,
fabrics, plastics or any other impervious materials.
Relief printing can be done in the same way as
woodcuts, or wood engraving, relief etching and
linocut or lino block.
More than two colours can be used in relief printing as
long as a neutral colour band is left until a later time to
set down first. To a greater extent, the process of relief
printing uses a similar principle as an inked block of a
stamp.
