7. Troubleshooting...

7.1 Encapsulating
1. Laminating film is not bonding to substrate or to itself at sealed edges:
a. Heat is set too low.
b. Film tension is too tight.
c. Bottom roll of laminating film is threaded incorrectly.
2. Wrinkles or irregular waves running across the laminated web (perpendicular to the
edge):
a. Heat is set too high.
b. Film tension is too loose (large, irregular waves).
c. Film tension is too tight (small, fine wrinkles – "orange peel" effect).
d. Roller speed is too fast.
3. Stretch lines running with the web (parallel to the edge):
a. Film tension is too tight.
b. Heat is set too high.
c. Substrate is too thick to seal fully.
4. Blisters on surface of substrate or along edge of substrate:
a. Heat is set too high.
b. Excessive moisture in the substrate being laminated.
c. Inks are not fully dry.
d. Rubber Rollers are not clean or are damaged.
5. Curling of the finished lamination:
a. Unbalanced tension on the supply mandrels; too much tension on the top supply
mandrel will cause the film to curl upward, or too much tension on the bottom
supply mandrel will cause the film to curl downward.
b. Bottom roll of laminating film is threaded incorrectly.
6. Wrinkling around edge of laminated substrate:
a. Substrate to be laminated is too thick; try a laminating film with a thicker adhesive
layer to compensate for the added thickness or flush cut the substrate.
7.2 Mounting
1. Print is not bonding to foam board:
a. Heat is set too low.
b. Roller speed is too fast.
c. Print was not placed on the adhesive side of the mounting board (ProMount
Mounting Boards only).
