Which edding marker is suitable for marking raw material and has an ink that withstands the colouring process at 130ºC?
Unfortunately, we are unable to make a recommendation because we do not know how the industrial inks relate to our ink.
Presumably, our ink is covered by the paint and is then no longer visible.
We have no ink that covers dark colours, except for our edding 750 paint markers, which are not suitable for marking fabrics.
