hi markus...

i see, for hole covering it is a good method (maybe the only).
i did know that but somehow didn't think of it....
but you all expose the film after laminating?

maybe it can be exposed by putting it into a laser printer assembly before 
lamination?
i think you know the bungard "barrel" exposure unit?
what do you think?
