| The
registration system consists of one computerized master console with touch screen
and a satellite unit for each of
the stations to be controlled. The master console is used primarily as the operator
interface, and sends control signals to each of the satellite microprocessors. The
satellite units consist of a microprocessor, local register controls, a registration mark
detector, cylinder phase detector, and a correction motor. Local controls are
available at each of the stations for minor register position adjustments. The performance
of our re-register systems is limited by the press itself. When running on a press
in good condition, "real world" registration accuracy would be close to
+/-0.008". Because of its superior design, installation, training, and maintenance of each system is a
breeze. You can have one fit into your existing press in as little as eight to twelve weeks.

The
Master Console
The heart of our system is a computerized
console with a touch screen monitor. The system prompts the operator to enter the
basic job parameters such as die repeat and register position. The system will also
record the setup information in a job file as a permanent record which may be retrieved
next time the same job is to be run.
Once any job is set up and running, a
graphic display of the amount of correction taking place and any residual error is shown
on the computer screen in real time. This features allows the operator to evaluate
the repeat quality of the material being processed and the amount of correction needed to
maintain register.
In the case where multiple stations are
being used, each station's register position may be changed independently of the others
either locally at the station, or from the touch screen. The master console is
capable of supporting from one to twelve stations.
Satellite
Units
A satellite unit is made up of the
software and hardware associated with a single print or die-cut station. Each unit
may be controlled from the station itself, or from the master console. All setup
parameters are communicated to the satellite units from the master console, therefore no
user input is needed.
Performance
The system itself has a resolution of .002
inch increments. This does not necessarily translate into the "real world"
tolerance of +/- .002 inches. The accuracy of the system is dependent upon other
factors not under the control of our system. The factors that typically influence
accuracy are: the condition of the basic press - specifically gear backlash, torsional
wind up of drive shafts, tension controls, cleanliness of drive rollers, and so on.
Other factors that may influence accuracy are the nature of the substrates run through the
press. For example, and unsupported 70 gauge polypropylene will stretch very easily,
especially when heated by the dryer, thus requiring good tension control.
Registration accuracy on a typcial
pressure sensitive film or paper stock, run on a press in good condiditon would be at
least +/- 1/64" and probably closer to +/-0.008" in the "real world".
For re-register, accuracies of +/- 1/64" to +/- 1/32" are more likely,
depending on the amount of repeat variation in the pre-printed material. The system
will accommodate compound errors such as registration errors inherent in the substrate
itself, in addition to offsets typical of a press speed change, and will cope with a
moderate amount of stretch. The system is designed to operate at speeds of up
to 300 frames per minute.
Installation
The installation time of our system is
from one to three days depending upon the layout of the machine, its age, model, amount of
optional equipment, and the number of stations being adapted.
Training
Operational training usually requires one
day of training and familiarization, followed by on additonal day of running a live job.
This extra day assures that the operator understands the system and all of its
capabilities in a practiacal sense. Any future support of course, is always
available if desired.
General guidelines that will optimize the
yield and operational ease of any given job will be provided by Total Register for
implementation in the planning and layout stages. These guidelines will be of
particular value when working with holographic materials since the "rules" may
deviate slightly from conventionally printed materials.
Maintenance
Our system has very few mechanical parts
and therefore requires very little maintenance. The only practical maintenance
required is routine cleaning of the CRT touch screen.
Delivery
All of the system components are standard
stock items. A delivery time of eight to twelve weeks is needed for the mechanical
design and adaptation of our drive motors and detectors to your particluar press.
Total Register has a vast amount of
experience in the area of registration systems particularly in the holographic field.
Our systems have produced many billions of re-registered products on very diverse
types of equipment all over the globe, and we are recognized as the world leader in
hologram registration equipment. If you have any questions, or need more
information, please feel free to contact us. |
