For difficult to print to surfaces such as glass and stainless steel, use our adhesion
promoter (I-UV-ADHPR2-200). Apply the promoter to the part of the substrate to be
printed to and in normal use, immediately wipe off. Printing can be done with adhesion
promoter wet or dry.
Always test the adhesion promoter on any new substrates before
printing.
To determine the proper print height for the material you are using, you will need to move the media
table with the substrate toward the print engine at SLOW TABLE SPEED. Achieve slow table speed by
pressing and holding
and then using the
and
. Make sure the top of the substrate
clears the bottom edge of print engine cover. Move the media table at slow speed until it is
approximately 2" (50mm) beyond the bottom edge of the print engine cover. The height sensor should
detect the height of the substrate and adjust the print engine up to the proper print height. DCS
recommends when printing to non-uniform materials or soft goods, always move the entire surface to
be printed under/through the LED head height sensor lights. Failure to do so can result in head strikes
and permanent head damage not covered under warranty.
If the print engine did not move up, it means the print engine was set too high to detect the substrate.
Press and hold
until the print engine stops moving down, then release (the print engine will raise
slightly). This will set the proper print height for the substrate.
Press
. You are now ready to print.
After pressing
, all buttons that control table movement are locked.
&
can still be used
to adjust the print head height. To escape the locked state, press
then move the table all the
way to the right
Note
If you are attaching irregular-shaped substrates, you may need to construct and use simple jigs or
fixtures to ensure that the material is positioned correctly. Any additional device used to position or
hold the substrate must not protrude above the surface of the substrate.
Printing onto Reflective, Shiny and/or Mirrored Surfaces
There are many reflective, shiny and/or mirrored (RSM substrates) surfaces that require a UV print for
personalization and/or decoration. These RSM substrates also include glass and crystal products. While
there is always some risk involved with printing to these surfaces, the risk can be minimized and
controlled when utilizing the following procedures. Failure to follow these guidelines could result in UV
light reflecting or refracting towards the print head. This increases the risk of curing the inks in the
nozzles and on the nozzle plate which could damage the print head. This damage would not be
covered by warranty.
1.
NEVER mount the RSM substrates onto the bed except to send the table to print home, adjust head
height, and print. NEVER have the RSM substrate mounted on the table with the head above the
recommended printing height, including during nozzle checks and/or filling of cartridges, etc. Exposing
the head at any time to an RSM substrate mounted on the bed when the head is raised above the default
head printing height allows the refracted light from the UV LED lamp to reflect back towards the head.
This can cause curing of the inks in the nozzles and on the nozzle plate, causing damage to the print
head.
2.
Never print onto highly reflective materials that are not flat sheets. As an example, if attempting to print
to mirrored vinyl, you first must attach the mirrored vinyl to a flat piece of material. If the mirrored vinyl
