Lamination Production Notes
This information is intended to be a starting point. Each laminator has its own characteristics that may vary
depending upon ambient conditions, laminator adjustments, age and condition of the laminator, etc.
Temperature, pressure, speed and tension adjustments may need to be made to optimise laminate adhesion to
the base material and to obtain flat, wrinkle-free prints.
•
Make certain that ink in high saturation areas of the print has completely dried before laminating.
•
Encapsulate prints intended for outdoor applications.
•
Hot melt adhesives generally give greater adhesion. De-lamination could occur if heat and pressure
settings are not correct for the media.
•
Keep the laminator supplies, media, and all work areas clean. Any debris trapped under laminates cannot
be removed.
•
Static charges build on laminator and supply rolls. This might attract dust. A static elimination device may
help.
•
Use temperature tape to verify nip temperature before laminating prints, especially prior to beginning
multiple quantities or oversized projects. Some laminators may have to be set higher in order for the nip
to reach optimal temperature.
•
Grommets may be added to laminated or vinyl prints to aid in display. To avoid tearing, strengthen the
print prior to setting the grommets by adding a 2" triangle of heavy laminate between the grommet and
the back of the print.
•
If laminated prints curl up, the top laminate tension is too high. Likewise, if the print curls downward, the
bottom laminate tension is too high.
•
If laminated prints curl up, the top laminate tension is too high. Likewise, if the print curls downward, the
bottom laminate tension is too high.
•
Boat waking can occur when the nip pressure is too high or too low or pull tensions are too low.
•
Improper cooling after lamination can result in wavy finishes or other defects.
•
Uneven waves or wrinkles can indicate a misaligned roller. Do not attempt to adjust a laminator roller
without proper instructions from the manufacturer.
Silvering can occur if heat or pressure is too low, or speed is too high. This can also happen if there is too
much moisture in the media prior to lamination. Heating or pre-drying before laminating the prints may
help correct this problem.
Refer to the Supplies Data Sheets section of this guide for instructions regarding lamination requirements
for specific media.
ALL 720 dpi PAPERS require higher temperature settings and slower speeds that 360 dpi papers to ensure
acceptable laminate adhesion. EX: NIP temp @ 240˚F and 1 FPM.
