Printing White Ink under Summa registration marks

Hello

Is there a way of getting the HP r 1000 to print a white bar under the Summa cutter registration marks so that the cutter can see the marks on a clear substrate?

I am using the Onyx rip.

#1 Hi Grant, I put a white vinyl strip on the cutting strip on the Summa cutter when i cutting for example 3M 8150 clear view.
