PALIGHT®
9
The four recommended lamination techniques for PALIGHT are:
 Cold laminating with a press using adhesive-backed paper
 Cold laminating using a vacuum press
 Hand laminating using transfer adhesive
 Hand laminating using spray adhesive
Cold Laminating with a Press using Adhesive-backed Paper
This process is most frequently used by commercial photo labs. Either of two types of liner films, a single release liner film or a double
release liner film, can be used for this process. The basic process for laminating with a press using adhesive-backed paper is described
in the following section.
1. Set the roller pressure properly for the thickness of the pre-coated mounting substrate.
2. Place the mounting substrate on a flat surface and expose approximately one inch of the adhesive by peeling back the release
paper. Fold back the release paper, making an even crease across the paper.
3. Carefully position the print on top of the substrate, using the folded release paper to prevent contact with the exposed adhesive.
Once positioned correctly, carefully apply the print to the exposed adhesive, pressing from the center toward the edges to ensure
a smooth tack.
4. Place the direction switch in the forward position and the speed control on medium.
5. Insert the materials to be processed into the laminator opening. Feed the substrate between the rollers until the pressure roller
rests on the tacked portion of the material.
6. Hold the un-tacked portion of the print up and against the pressure roller. Feed the substrate through the rollers while peeling
the release paper off the mounting substrate with one hand. To prevent wrinkles, the print must be held against the
roller with the opposite hand while the substrate feeds through the press.
7. Remove the mounted print from the rear of the laminator and trim it to the required size.
Coating using Single Release Liner Films
1. Set the pressure properly for the thickness of the substrate(s) to be processed.
2. Load the supply roll of pressure-sensitive adhesive.
3. Pull approximately 12 inches of adhesive film forward off the roll. Rest the film, adhesive side up, on top of the pressure roller.
4. Create a leader board by cutting a piece of substrate slightly larger than the width of the adhesive film and approximately four to
six inches long. Lay the leader board across the adhesive film and smoothly adhere the bottom of the leader to the adhesive.
5. Place the direction switch in the forward position and the speed control on medium.
6. Pull the leader down and push it between the rollers. Feed the leader between the rollers approximately three to four inches. Be
sure that the adhesive stays firmly adhered to the leader.
7. Once this process has been completed (referred to as “stringing the web”) and the adhesive is feeding without wrinkles, the
laminator is ready for production.
8. To coat, feed a substrate behind the leader board and between the roller while depressing the foot switch. Feed until the substrate
exits the rollers and automatically stops feeding. At this time, another substrate may be fed between the rollers for coating. This
process is suitable for films with a paper release liner and leaves a 3/8” to 1/2” gap between the coated substrates to facilitate the
trimming process.
9. After exiting the laminator, the coated substrates should be split apart and trimmed.
Coating using Double Release Liner Films
Coating with double release liner film, requires the use of a take-up mechanism to automatically remove and rewind one of the
release liners during the coating procedure.
1. Set the pressure properly for the thickness of the substrates to be processed.
2. Load the supply roll of pressure-sensitive adhesive.
3. Adhere double-stick tape or a pressure-sensitive adhesive film, to the surface of the take-up shaft.
4. Pull approximately 18 inches of adhesive film forward off the roll and adhere one release liner side smoothly to the take-up shaft,
taking care to ensure that the film is square with the supply roll and no diagonal wrinkles are apparent.
5. Separate the adhesive film from the release liner secured to the take-up shaft and pull the adhesive film and remaining release
liner down so that it rests adhesive side up on top of the pressure roller.
6. Lay a leader board the same thickness as the substrates to be used across the exposed adhesive.
