Abstract
The application of Narrow Web UV-flexographic printing has several advantages
compared with offset printing. In particular, they are the lack of
the operation of water-ink balance setting in the technological process, the
ability to print on a wide range of materials and so on. Though the imprint
quality is clearly based on standards in offset printing, there are no clearly indicated
requirements for Narrow Web UV flexographic printing. The absence
of such requirements on quality parameters of the technological process of
Narrow Web UV-Printing predetermined conducting its analysis with the help
of expert surveys.

Abstract
Packaging industry’s raw material producers face continuous challenges of
sustainable development. Besides raw material and energy consumption
mitigation, essential functions of product protection must be maintained.
Re-use and recycling of waste materials must be provided, which is required
by the European Union directives as well. Multi-beverage carton recycling is
even more difficult due to the use of various materials, due to their diverse
properties and qualities. The introduced paper is part of a complex study,
which aims to prove that utilizing dry-grinding technology and no additives,
semi-finished products can be produced for the packaging industry.

Abstract
Print inks have assumed an important role on finished materials, such as
plastic packages, which can have a long lifetime when disposed as municipal
waste. By this way, it is important to evaluate the influence of physical
parameters on the degradation of shot lifetime substrates covered by pigmented
print inks cured by UV radiation.

Abstract
Printed textile materials are often exposed to certain external impacts. One
of the most common impact, these materials are subjected to, is thermal
load. This effect causes certain changes in textile fibers as well as changes of
ink colour reproduction printed on these materials. In this paper is presented
an investigation of the series of thermal loads effects on print quality parameters
of digitally produced impressions on textile substrates. The research
includes basic print quality attributes: colour reproduction, macro non-uniformity
and quality of line reproduction. Investigation results indicate that by
increasing number of thermal loads, bigger changes in colour reproduction
occur. Also, the influence of the series of thermal loads on mottle and line
reproduction variations is confirmed, as well as the influence of printing
substrate characteristics on print quality.
