How to Handle Media
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.
Media-Related Application Bulletins
For additional information on various aspects of handling and managing
media refer to the Customer Support web site. See Appendix A of this

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-directional 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.
