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.
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 location of the cards. Note: these cards can be stacked, but if more than
two of them are stacked, the carriage will collide with them if you print at zero media
height. Always check the height if you use multiple stacked cards so that they match
the height of your media and the set the carriage height accordingly.
