6.7 Encapsulating
This process involves completely sealing an image between two heat-activated films.
Once the machine reaches the operating temperature, the laminator may be stopped, the
top roller raised and webbed as per the following photographs and diagrams, refer to the
Temperature/Speed chart on page 16 for settings and recommended film combinations.
Preparation:
Note:
Check if the film widths of the lower and upper web are the same!
It is advisable to use slightly wider films compared to the print width. This way the print can
be trimmed with a border and not too much film waste is generated, Mount rolls onto the
unwind shafts with adhesive facing you. Web as follows:
1. Remove the image guide and the infeed table.
2. Pull the film evenly over the top roller and across the face of the rollers.
3. Split the film from the release liner and pull the film evenly across the face of the
rollers.
4. Pull the film up from the bottom unwind station and over the face of the top laminating
roller. The films will then heat and stick together.
Note:
Keep the film under tension (turning the top unwind manually) to prevent the
photoelectric eyes being tripped.
5. Place the feed table into position, and set the roller nip to 1/16” (2mm) to
accommodate for the thickness of the leaderboard.
Note:
Use the 2mm thick leader-board supplied with the machine.
6. Depress the foot switch and then using the provided leader-board push the films into
the nip of the rollers. Using the foot switch, advance the leader between the pull rollers
until the end comes out of the pull-rollers. Release the foot pedal and set the nip knob
to 0mm.
7. Moving to the rear of the laminator, with the film and leaderboard hanging out of the
machine, cut off the leaderboard from the front of the laminator, run the film until the
output is wrinkle free. Best results will be obtained when the film unwind tension is
zero or very light.
Wrinkles, visible on the roller face do not show on the output.
8. Refit the image guide on the infeed table.
YOU ARE NOW READY TO FEED IMAGES.
