| Features |
| The
Front End Terminal |
| |
The front-end terminal of is
a very user-friendly interface
giving complete visual presentation
of the happenings on the printing
machine. The options are to run
the machine in auto or manual
mode. In auto mode, InkStat takes
over and controls the machine.
In manual mode, all the cylinders
can be moved either individually
or in selected pairs. The manual
mode is used only during diagnostics
and maintenance.
The default display gives you
all the dynamic conditions on
the front-end terminal. This clearly
shows the errors and progressive
corrections visually. It displays
speed, cumulative copies and other
vital information that production
personnel would like to know related
to the EIS / MIS. |
| Color
Mark |
| |
A digital encoder is deployed
to provide very fine control over
the length of the newspaper. This
gives the printer a freedom to
choose the mark position. The
encoder can be tuned to accuracy
better than 0.5 mm.
The cameras are triggered to capture
the image grab as soon as the
marks appear in front of the camera.
This trigger is simultaneously
or individually applied to all
the web units. The synchronization
eliminates unnecessary grabs and
hence enhances algorithmic efficiency.
The trigger signal is derived
from a logical relationship between
Proxy and the encoder pulse train.
The philosophy to “search”
the mark is very innovative. The
algorithm identifies the color
marks and cleans up the image
of any smudge that may be present.
Having acquired the image it finds
out the boundary of the mark and
computes the distances between
the images in both the directions.
The InkStat software has a unique
algorithm never used before to
detect a Plate Skew in the image
of a given color. |
| Registration |
| |
The camera captures the images
continuously irrespective of the
printing speed. Once the desired
correction is computed, the motors
are actuated appropriately depending
on the correction required. Subsequent
image grabbing continues dynamically
while correction is applied. These
images are stored in a pre-designated
directory for the InkStat software
to pick up later for analysis
and diagnostics. |
| Manual
over ride |
| |
There may be a necessity to
manually over ride the auto setting
of the InkStat. Typically this
may be required in case of maintenance
or when color marks are not printed
or a catastrophic failure due
to printing machine or the color
registration system. |
| EIS
/ MIS |
| |
InkStat provides, information
on vital production and wastage
parameters in a comprehensive
integrated EIS / MIS for incorporating
it into native ERP systems. |
