Why is lamination bubbling?
The temperature is too high and is "gassing" the ink. Reduce the temperature. The majority of inkjet output must be properly cured (most manufacturers recommend 24 hours or at least overnight). Even properly cured inkjet requires low-temperature films, such as RoyalamII or Lomel, in order to avoid gassing.
Tip Slower speeds work best with lower temperatures by allowing the adhesive more time to fully melt. Some Photobase Papers are not suitable for thermal lamination. Check manufacturer.
