Section V: System Startup and Adjustments
NOTE : Foil positioning, tension, and process temperature will all vary somewhat depending on differences in print patterns,
substrates, press speeds, foil performance, etc. Some experimentation may be necessary to obtain the best results with your
application. For the reasons listed above, the following instructions have been left intentionally brief.
1. Web press as usual, then web the foil from the unwind through a web idler approximately 3-5 inches ahead of the station,
then along the web through the die and base roll. Strip the foil about 2-3 inches after the die and to the waste wind-up.
The foil should lie flat against the web as it enters the die, with little or no wrinkling during operation. The distance
from the die where the foil joins and leaves the web will vary according to the actual application, but the foil needs to be
“paced” with the web at some point, to keep the foil from traveling faster than the web. See Figure 1 and Figure 2 on the
following pages for a basic webbing diagram.
2. Make sure the MAIN POWER switch is in the “OFF” position. Connect the power to the control unit and turn the
MAIN POWER switch to the “ON” position. After an initial diagnostic check, the temperature control module will
display the current set point in the middle display and the current die temperature in the upper display.
3. Set the desired process temperature (consult your foil manufacturer) by pressing the UP or DOWN buttons until the
desired temperature appears in the “SET” display. Press the ENTER key to lock in the new set point. If you do not press
the ENTER key within 5-10 seconds after keying in a change, the control module will return to the previous set point.
4. As the die nears the set point, run the press at 50-75 FPM. Turn the impression mode switch on the control unit to the
“AUTO” position and observe the action of the base roll to be sure it rises to the print position.
5. Bring the die into contact with the web and apply slight pressure with the pressure adjusting screws. Note print quality
and current die temperature. Lock pressure-adjusting screws, but do not over tighten.
6. Adjust any other press operations as necessary, in accordance with standard operating procedures.
7. After all other press operations have been adjusted for quality and register, gradually increase press speed, adjusting
pressure and temperature to maintain foil print quality.
