| SINGLE-SIDED LAMINATION with PRESSURE-SENSITIVE (Cold) FILM This tutorial describes the application of a pressure-sensitive overlaminate film to one side of a graphic that has already been mounted to a rigid substrate. This procedure also works for unmounted graphics, which are placed on a rigid "sled" or carrier board prior to processing. For more on the topic of using a sled, go here. |

Settings TEMPERATURE: Pressure-sensitive films do not require heat to bond, however, many will benefit from the application of lower temperatures at the Main Rollers. Do not exceed 120 F degrees. MAIN ROLLER SPEED: 1 - 6 ft / min. Some more rigid films benefit from slower speeds. See manufacturer's recommendations. PRESSURE: 30 to 60 psi (varies according to machine). PULL ROLLERS: Up. Set the gap to accommodate the thickness of the mounting substrate or sled. See Section 4 of the Textbook for more training in laminator set-up and webbing techniques. Procedure 1. Load a roll of pressure-sensitive overlaminate film onto the Upper Supply Unwind Shaft with the lead film edge facing up. 2. Unwind the film and bring the edge underneath the Idler Bar. 3. Separate the release liner from the film and attach it to the Upper Take Up Shaft. 4. Handling the edges of the pressure-sensitive film, bring it over the top of the Upper Main Roller and position is squarely on the roller. Go to Section 4 for more on laminator setup and webbing techniques. 5. Use a Leaderboard to push the hanging film into the nip of the Main Rollers until it is wrapped tightly and evenly around the top Main Roller. Then turn on the Main Rollers and process the leaderboard through the rollers. Stop the machine when most of the leaderboard has passed through, and only 1/2 to 1 inch of the board is still exposed. 6. Push the mounted graphic or sled up to the edge of the leaderboard and butt it up against the back of the leaderboard. Turn on the Main Rollers and process the mounted graphic or sled through the rollers. 7. When the graphic has passed through the rollers, cut the web of the film behind the idler bar using a "zippy blade" or similar safety knife. Do not stop the laminator until the graphic has passed completely through the rollers. 8. In order to take up the extra film that will pass through the rollers after cutting, use either a second leader board or cut off the first leader board and re-insert it into the roller nip. TIP #1: Make absolutely certain that the leaderboard and the mounting substrate/sled are the same thickness. TIP #2: Adjust the Take Up Shaft speed so that the release liner is pulled away from the film just before it makes contact with the Main Roller. This procedure minimizes the time the adhesive is exposed to the air, and helps reduce dust and stuff. Take me to Tutorial #2. |
