I found this on Brothers Q&A site.
Q. What color of garments can it print on?
A.We can print on white and many light or pastel color shirts, additionally some dark color shirts as well.

OK I stand corrected but what does SOME DARK COLOR SHIRTS mean?
Can you explain what they mean by this statement. I would have thought without the white ink to underbase your print you would not be able to print darks as the shirt would show thru.
