How to avoid waves/wrinkles while using a laminator?
Waves will occur if the speed of the film within the nip is not exactly equal across the width of the roller or the proper brake tension has not been applied on the film, as well as back tension on the printed media. Waves in your finished print that run in the “web direction” are usually cased by stretching the materials you are laminating together. Classified as film distortion, these waves are more visible when you have a gloss finish. The direction they run will show you which machine adjustments need to be made. Start by reducing the clutch pull pressure. When you process films with thermal adhesives the films soften when subjected to heat. Too much clutch pull pressure can physically stretch your laminated films leaving distortion waves. If you do not have an adjustment for your pull rollers clutch, other items such as using your chill rollers, reducing break tension and lowering your temperature setting will help resolve this issue.
