| Why should you
be using video web inspection ?
Video web inspection is
not a new technology and certainly not a passing trend that
will be fashionable for a while and then fade away. The
first video web inspection systems appeared on the market
in the mid 1980s and you may be interested to know that
Visi-tech staff were involved in the design of these very
first systems.
Over the past twenty years
video inspection systems have become extremely popular and
common-place on web printing machines all over the world.
The reason for its popularity and success is quite simple.
The technology works well and produces significant benefits
for the printer. If you're running a web printing machine
and don't have video web inspection then you are probably
losing money.
It doesn't matter what
type of printing process you are using - flexo, offset,
gravure or screen - if the product is being printed onto
a continuous web then at speeds above 30 to 40 m/min the
printer is unable to effectively examine the print quality
by eye. Using a video web inspection system not only allows
the printer to view the web at high speed, but with magnification
up to almost 100 times he will be able to see detail and
dot structures like never before.
Video inspection systems
have been proven time and time again to improve the productivity
of web fed printing machines and offer the user a remarkably
fast return on their investment. Use of a video web inspection
system will provide the user with the following benefits:
Faster running speeds
Due to the fact that the printer is
able to use the video inspection system to view any part
of the web in great detail, he will be able to run the
job as fast as the machine will allow, significantly reducing
production time and increasing productivity.
Reduced set-up times
Using the high magnification of a video
inspection system the printer is able to concentrate on
specific regions of interest such as a register mark and
view this in great detail on the monitor. As the press
is being set up and adjusted for register the progress
can be clearly seen in real time on the inspection system
and the set-up can be reduced significantly.
Reduced waste
Using features such as Dynamic Scan,
print defects can be quickly identified and remedied before
too much waste is produced. With expensive substrates
reduction in waste can offer very significant savings.
Improved product quality and customer
satisfaction
Apart from the immediate savings made
by improving set-up times, running speeds and reducing
waste, there are additional benefits that can be seen
through improved quality and customer satisfaction. By
identifying defects more efficiently, quality will be
improved with less defects finding their way to the customer.
Additionally the improved efficiency and reduced manufacturing
time will also provide a better service and improved customer
satisfaction.
In summary a printer running a web press equipped with video
web inspection will produce superior quality and will be
more productive than a printer on a press without video
web inspection - and that means the press will be more profitable.
