Thermal Expansion
of Media
Some media, such as Styrene or plexiglass, is subject to
expansion when subjected to heat.
If multiple pieces of these 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.
When overprinting on media that will expand 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.
Note that color-to-color registration may be affected if the media
expands significantly between printing the first and last colors.
Using a generic ICC
Profile
If an ICC profile is not available for a particular media and it is
not possible/convenient to create one specifically for that media,
determine the ink restriction values required to achieve Dmax for
that media. Then select an ICC profile for another media that
uses the same ink restriction values and has similar dot gain
characteristics and the result may be satisfactory.
Imaging on Fome-
Cor
Fome-Cor has a tendency to warp when heat is applied.
However it will go back to it’s original shape once cooled. Media
Holder Strips (aluminium bars) with a 45 degree chamfer are
available to hold down the Fome-Cor. The bars are 2” wide and
32” long. Also, Fome-Cor’s color accuracy is very sensitive to
the printer ink temperature. The printer should be brought up to
a steady state temperature prior to printing.
Profiling Tips
It is very important to warm-up the printer prior to setting ink
restrictions, linearizing, or creating an ICC profile. One method is
to ensure a warm printer is to run multiple copies of the test
image. Depending how warm the printer is run 4x3 or 4x4 or 4x5
copies of the linearization test image. Another excellent option is
too enlarge the linearization and ICC test prints; the Eye-one can
then be used without the plastic slider to read the patches to
read the patches a column at a time. For the ICC patches,
preflight the test image, double the image size, double the tiling
size, and print with columns set to 1 and rows set to 2.
