Media Adhesion
Some media have better adhesion quality than others. Factors such as the amount of ink
used and the amount of curing energy from the UV lamps can affect adhesion.
For more information on media adhesion, see Application Bulletin 6 on the customer
support web site.

Thermal Expansion of Media
When imaging on media that will expand when subjected to heat (e.g., styrene or Plexiglas,
etc.), don’t wedge the media by butting other material against it as this may cause the
media to buckle. Also if multiple pieces of the media are used, allow enough space between
the pieces to allow for thermal expansion. Placing tape on the table prior to laying down
the media will prevent ink from being imaged onto the table. Finally, if you overprint
on media that expands when heat is applied, we recommend that you group the desired
image with a preceding image so the printer is a consistent temperature when starting to
print the desired image.
Thermal Deformation of Media
Some heat-sensitive media may deform when subjected to high heat. If this occurs you
can reduce the lamp power from the default setting of 7 to find a compromise level that
allows the ink to cure but does not warp the media. You can also try to print uni-direc-
tional using only the trailing lamp (to do this set the power of the leading lamp to 0).
Media Registration
Media can be registered on the table using the table rulers . These rulers are printed on
the table and provide a horizontal and vertical rule that originate from the 0,0 print origin
point on the table. The rulers can also help to provide offset distances if you need to start
a print away from the origin point.
Alternately, the media registration cards can be used to register media if it must be
placed consistently away from the table rulers. These PVC adhesive-backed card can be
placed anywhere on the table to set new coordinates for print origin to enable consistent
registration of media in that location. Make sure that you set the offsets to match the lo-
