Angle your RSM substrate slightly so that it slopes downhill away from the capping station.
Printing onto thin or low melt-point plastics (e.g. PVC)
If you are using a thin material, the UV Lamp intensity may need
to be adjusted so that the material does not warp and scrape
against the print head.
There is a dial which can be used to adjust the intensity of the
lamp to accommodate varying substrates.
Turn the dial counter-clockwise to lower the intensity. The knob
has 10 detents/clicks for easier adjusting. DCS suggests a level of
between 6 and 8 when printing to thin plastics or low-melt plastics
(such as PVC).
Some testing may be necessary to determine the correct combination of resolution/print mode
and UV lamp intensity. All substrates should be tested and confirmed by end users as suitable
with regard to print quality and adhesion of the inks to the substrates.
