Re: Polarized film printing
thanks for the reply.
yeah, the hard part is figuring out how to make the image disappear and re-appear.
All they gave me was a printed sample (silkscreened, no less). Spent several days googling to no avail.
It has a black halftone on the face of the plastic and a solid silver on the back, with who knows what between the silver and the plastic to make it work.
There's something done to the back side image, I know it's like an 85 line screen, so no geometric screening that would run perpendicular to the polarized film...
and yes, it is on a sheet of polarized film
PS.
Yes, we just printed a "Void Pantograph" job the other day, that stuff is easy...
once you get the right file that matches your output res and your printing press...
gravy!
