There is nothing in Plotter that would be able to make a specific compensation of any sort for something like this. To Plotter, it doesn't matter what the light source is - it just matters what the input test data values are.
I suspect that there will be little to no difference in the results though. Since everything is contact printed during testing I wouldn't think the type of illumination would affect the tests all that much if at all as long as the light is evenly distributed.
If it turn out that there is some difference and it turns out to be a linear difference, then you can use Plotter's exposure adjustment factor. That's about the only option though.
