Rapid Highspeed
The RAPID Highspeed comes with the same print head technology as the RAPID Wire but with a
different head cover. The headcover of the RAPID Highspeed is designed for high-speed
applications that:
•
require a larger distance between print head and head cover
•
whereby the
recommended
distance is
5 mm
•
and/or for substrates that are not suitable for the RAPID Wire print head
With the special design, it is possible to mount the print head in a slightly inclined position. This
will prevent the printer from becoming contaminated by bursting ink drops.
Due to the larger distance between print head and substrate, the operation speed of the RAPID
Highspeed is a bit lower than with the RAPID Wire.
Whereby the difference is not based on technical restrictions but on the quality of the printouts.
Which means that the RAPID Highspeed may be operated at the same speed as the RAPID Wire
but the quality of the print outs are not expected to be as good as they are with the RAPID Wire.
The print head of the RAPID Highspeed: The slightly angled surface allows an optimized
mounting of the print head.
Ink drops that hit the surface of a substrate
tend to burst in smaller drops and not all
drops are absorbed by the substrate.
When the print head is mounted vertically, the
bursting ink drops may lead to a faster
contamination of the print head.
With the angled surface of the outlet side of
the print head, it is possible to mount the
print head in a slightly inclined position.
The ink drops will not hit the substrate at a
90° angle. Therefore, the bursting ink drops
will take a direction away from the outlet,
which will lead to less contamination of the
print head.
Generally: the distance between print head and substrate should not be below 5 mm in order
to avoid the contamination of the print head by rebounding ink drops. A larger distance may
have negative effects on the quality of the printouts.
