26 Application Processes
6.8 Pre-Coating
This process is used to coat substrates with a self-adhesive coating onto which images
can be mounted. The same process is used to create a carrier board (sled).
Preparation:
Mount the roll of self-wound pressure sensitive adhesive onto the top unwind of the
laminator with the exposed adhesive facing you.
Have a leader board ready of the same thickness as the boards to be coated.
1. Pull the adhesive down from the top unwind station and over the top roller evenly,
and down across the face of both main rollers. Remove the infeed table and the Image
Guide for a moment to do this.
2. Measure the thickness of the board(s) to be coated, and select the correct nip setting.
3. Press the foot switch and, using the leader board, push the adhesive into the roller nip.
Release the foot switch when the rear edge of the leader board is almost leaving the
roller nip.
4. Position the board to be coated into the nip, and choose a speed setting.
Note:
When coating boards, ensure that the next board to be coated follows the previous
board without any gaps.
Follow the last board being coated with the leader board once again to allow the
final board to clear the laminating rollers and then stop the motor and raise the top
roller.
6.9 Mounting using a ProSEAL
®
Mounting Board
1. Refer to the instruction sheet packed with each box of ProSEAL Mounting Boards for
specific instructions on mounting with a ProSEAL Board.
2. Also, refer to the instruction sheet for information on Compatible Media, Process
Conditions and Technical Information.
3. Place the image to be mounted on the adhesive-coated side of the mounting board
(dull side of the board). Cover your print with the “cover sheet” as marked; (included
with each box of ProSEAL
Mounting Boards); please be sure that the board is
completely covered by this sheet.
4. Set the Control Knob to the correct setting that matches the Mounting Board
thickness.
5. Insert the board into the inlet opening. Ensure the board will enter centered and
straight. A gentle push may be required to start the board into the machine. Hold the
edges of the board until it is engaged in the unit and the laminator begins pulling it on
its own.
6. The board will feed through the laminator and automatically exit at the rear of the unit.
CAUTION! The board will be hot! Allow it to lie flat while cooling.
