- Flush Mounting on Pre-coated Boards
Begin the actual mounting process by peeling the protective release paper
back about I" along the short side of the pre-coated mount board. Fold back
the release paper and crease it. Now position the print on the mount board.
The fold in the release paper will keep the print from touching the exposed
section of the adhesive. Once the print Is correctly lined up, press its edge
down onto the adhesive. This tacks the print in position. The edge of the
board that the print is tacked down to can now be I inserted into the
laminator nip rollers. Set the speed control to a slow speed. Push the board
against the nip rollers and turn the machine on just long enough to insert the
edge of the board into the rollers. You may need to push the board into the
press as you begin.
Once the edge of the print is inserted into the nip rollers, stop the press.
Now wrap the print gently around the top nip roller. While holding the print
in this fashion, peel all the release paper from the mount board. Now operate
the motor until the board passes through the press mounting the print. Try to
hold the print so it wraps around the top roller as this process is carried
out. Always let the rollers do the mounting. DO NOT lay the print down on the
mount board and then try to press it down with the rollers. Your understanding
of this process may be helped by using the analogy of a squeegee. The
Cold-Mount press is NOT being used to generate a great amount of pressure
during this operation. Rather, the technique of letting the rollers apply the
print to the adhesive works to prevent any air from being trapped under the
print. The rollers "wipe" the print down onto the adhesive surface in one
- Overlaminating Prints
Overlaminating prints requires a good deal of pressure. Unless the adhesive is
forced into 100% contact with the print image, air pockets may be created.
Since you will be looking through the adhesive layer these air pockets can
cause light to refract in them, giving a graying or mottled effect to the
The solution to this problem is to increase the amount of pressure used during
the initial application of the overlaminating film and to apply it slowly.
These actions will cause the adhesive to run or flow as the nip rollers
traverse the surface of the print. The amount of pressure needed will vary
depending on the substrate used, the type of overlaminating film used and the
width of the piece being laminated. We recommend that you overlaminate before
mounting and use sheeted material slightly larger than the size of the piece
being overlaminated. You can purchase sheeted overlaminates a size larger than
your prints, or purchase the material in rolls and sheet it yourself. Run the
print and the overlaminate through the press on an oversized piece of Coda's
adhesive-coated Gatorboard with the silicone release liner still Intact. (For
example, use a 16 x 20 Gatorfoam board with an 11 x 14 overlaminate for an 8 x
10 print.) The adhesive- coated Gatorfoam provides a stiffener as the material
goes through the press, and the materials won't adhere to the release paper.
(Be sure to have the white side of the board facing up - this is the side with
the release paper.) Peel back about an inch of the release paper on the
overlaminate film and tack it to the stiffener. Put the board and the
overlaminate in the press until the rollers securely hold the overlaminate.
Peel back the remaining release paper on the overlaminate and let the film
drape over the top roller. Now slip your print in, face up, and wind slowly
through the press without stopping. Peel the laminated print off the
stiffener, flip over, and trim the excess laminate. You can then mount the
laminated print to the substrate using less pressure.
