Reduce laminating pressure to eliminate spots & wrinkles
If you have experienced small spots in your laminates or have had prints wrinkle when mounting, the problem may be too much pressure. This may be true because the boards are slightly thicker (common in the summer) or the roller gap has changed. What happens is the extra pressure will cause your print to raise just before the rollers and the laminate film will stick to your print before being pressed down by the rollers. This premature adhesision can be uneven causing air pockets or spots (sometimes called silvering). Excessive pressure will cause wrinkles.
To eliminate this, either set the gap for the rollers to the next size up (if you are running 3/16″ thick board, try the 1/4″ setting. If you do that and you do not have enough pressure for good lamination, hold onto to your print at the corners (once the rollers have grabbed your print and keep your print taught and not raised before the rollers.
