P R O B L E M :
Wrinkling of one side of the web or skewing of images as they are
laminated indicates that perhaps the pressure on one side of the laminating or
pull rollers is greater than on the other.
S O L U T IO N :
Skewed, wrinkled images are most often generated by skewed
trimming or skewed feeding. If the leading edge of an image is not trimmed at
right angles, the nip will catch one side before the other. Unless the paper is
fairly heavy and stiff, the item will most likely be ruined. The same thing will
happen if the operator feeds an item in with the leading edge not parallel to the
nip.
If trimming or feeding are not problems, check to make sure the roll tension is
balance. Make sure the rollers are fully closed. Make sure they are in the locked
position. Consult your laminator vendor if the problem persists.
P R O B L E M :
Myriad small bubbles of air caught between the image and the film,
known as silvering.
S O L U T IO N :
Silvering is often seen when laminating with cold films. With many
cold films, this silvering will go away in a day or two as the adhesive penetrates
and pushes the air through the back of the sheet. You may also use heat on the
top laminating roll. Set temperature at 120F. (See temperature control
instructions on Page 13.) This should help eliminate any silvering.
