Abstract
In this paper, the relation between “Industry 4.0” and the metadata
formats JDF/XJDF is discussed. While “Industry 4.0” is a term for a certain
method of production in general, the XML-based data formats JDF/
XJDF are commonly considered being technologies for implementing
Industry 4.0 production in the graphic arts industry. The paper shows
that the original architecture behind JDF, however, is more compatible
with Industry 4.0 that the new XJDF format. For this purpose,
some important features of these two data formats are outlined.

Abstract
Through several projects in Slovenia, e-learning materials have been developed
over the last decade, with some primary and secondary schools already
using them successfully in their educational processes for several years. The
objectives of this research were to analyse the development of e-learning
materials, in particular the process of creating e-textbooks, to identify experiences
in the use of e-learning materials and to determine their availability
on the market. In order to understand the development process, our research
involved the creation of i-textbooks. The problems we encountered during
the creation of i-textbooks are presented in this article. The results showed
that teachers are satisfied with the use of previously developed e-learning
materials. They also agreed that traditional textbooks cannot be replaced
completely by e-textbooks. However, they do represent an important motivation
tool that assists them in facilitating the transfer of knowledge and helps
learners to better understand and learn the contents of different subjects.
The e-learning materials present on the Slovenian market are freely accessible
or require payment, depending on the editor. A great deal of e-learning
materials is also inactive, as was emphasised in our research.

3. Investigation of the effects of different ink density
values on color gamut in offset printing

Abstract
A standard color gamut can be obtained with CMYK samples that are
printed with an offset printing system according to the ISO 12647-2:2013. It
is possible to enhance or widen the color gamut during the printing process
by interfering with the density and dot gain characteristics. Printing with a
wider color gamut provides a more vivid area and more depth in color.
In this study, print trials were conducted at first with standard values
(density, dot gain and such). Then another trial was conducted by
changing the density values respectively during the trial. Ink density
values for all colors were decreased from the standard value as -0.15D,
-0.30D and then increased as +0.15D, +0.30D. Color gamuts of the
trials were calculated and compared at the end. It is found that ink
density values directly affect color gamut in offset printing. It is also
found that the color gamut decreases equally when ink density values
decrease and vice versa. However, some printing problems occurred
with high density values even though it gave an expanded color.

- 4. Creative design software: Challenges and
opportunities to the graphic designer in Zimbabwe

Abstract
The study sought to investigate the nature of issues facing the graphic
designers with regards to software usage and upgrades. Technology has
changed the way graphic designers do their job and this has brought
some challenges and opportunities to the creative design industry in
Zimbabwe. In depth interviews were carried with graphic designers
currently in practice and also an open ended questionnaire was used to
solicit for views from the designer perspective. From the findings it was
concluded that younger designers are enrolling for the graphic design
qualification in institutions of higher learning across the country. Most
designers highlighted that they prefer using Adobe suite as a software
package of choice even though they do not acquire the official proprietary
software license. To a larger extent the graphic designers make a choice
on software to buy depending with their hardware capabilities.

- 5. Light fastness of printing inks: A review
- Pages: 37-43
- Cem Aydemir, Semiha Yenidoğan
- Abstract | Download | View
Abstract
Light fastness, in its broadest sense, is the resistance of colours to fading under
the influence of a light source. Light fastness is one of the most important
physical, and therefore visual, properties sought in both pigments and in the
inks. Artificial and natural light causes most pigments to fade resulting in colour
change. The light fastness of inks is important especially in the packaging
and advertising industries. The posters and advertisements hung on the
billboards used especially in outdoor advertising, printed product packaging
and other printed products exposed to sunlight require high degree of light
fastness. In this study, light fastness and factors affecting the resistance of
the colour to the light were investigated and suggestions were made regarding
high light fastness in terms of printability.

Abstract
The present work investigated the current state of letter writing methods
in the emerging field of engineering education and identifies difficulties
experienced by scholars and educators who have been involved in teaching
the subject Engineering Graphics. Most of the students are not able to follow
the methods that are used to write letters since technical lettering being
written in graphs by various authors of engineering drawing do not follow
a specific procedure, and no standard practice is maintained so far. After
thorough discussions with faculty members and students, it was identified
that the difficulties with lettering were: d/h ratio and, curvatures. The ratio
of height versus width of the capital letters varies in different ways which
appear to produce a sense of confusion among engineering students and
practitioners. The curvatures of various letters are not standard and are
very difficult to remember. This took our interest for investigation, and a
new method of lettering was developed and proposed, which is very simple,
easy to remember and provides a standard method to be followed.
