>>But as soon as I add Ultratone magenta position toner inks to the mix I
get the roller marks
again.<<

FWIW, from my experience I think this is just a characteristic of the MIS
Ultratone inks on non-matte surface.  They do not dry "enough" right after
printing to prevent damage from handling by the printer feeding mechanism.
The higher the density, the more likely the problem.
