| Abstract in english: |
Printing plate is carrier of an image which will be print out and multiply in the
reproduction process. It consists of surfaces which will, by using a printing ink,
transfer the digitally made image onto the printing substrate. Quality of the
image and final imprint depend on a number of parameters which have to be
monitored and adjusted during the printing plate making and reproduction
processes.
Quality control of printing plate can be conducted by observing the printing
areas, made of photosensitive layer; or by observing the non-printing areas,
made of aluminium-oxide. Quality of the image on the printing plate surface is
usually controlled by using different devices for measuring the quality level of
plates. These devices work on the principle of determining several parameters
for monitoring the quality of printing plates, where, the most significant is, the
surface coverage of the printing elements.
Beside those devices, market today offers a range of alternative methods which
allow the determination and characterization of tones by using a software
support for image analysis. Those methods are using the microscopic images of
the surface and can define the surface coverage of printing elements and other
necessary information about the quality of the printing plate.
The aim of this work is the defining of printing plate quality level through
introduction of different image analysis applications. The results of this research
may indicate that it is also possible to use alternative applications for monitoring
the quality of the printing plates. Furthermore, this paper would provide a
general overview of quality control possibilities for printing plates and could be
useful to the systems where such controls are regularly conducted. |
