Oh, sorry if I didn't phrase the question very well.
I'm familiar with the terminology,
but someone said they had used white silkscreen as a reflective background for display boards,
(which effectively becomes the mask)
and it just got me wondering if the materials had different properties.

I SUPPOSE I could do the research on my own instead of bothering everybody (grin)

thanks though,
Jack
