Can you advise me the standard (or spec) of the white backing and
black
backing ?
Regards,
Steven Hwang
Black backing is specified in ISO 5-3. It has to have a StatusT
density of
V1.60. I don't know the specs of the white backing and I'd be curious
to
know what they are.
ISO 12647-1:2004
Graphic technology — Process control for the production of half-tone
colour separations, proof and production prints -
Part 1: Parameters and measurement methods
says in part 5.6:
matte, opaque white backing with
C* < 3 and L* >92
and the fogra adds: non-fluorescent.
Hope this helps
Rolf
