Please enlighten me!
Hi again
The ISO 12647/2 sheetfed TVI is on a 50% between 15-17% for Type 1 or 2
coated papers, positive plates, on web off set on Type 3 coated paper, 19%,
again for positive plates. In all cases if the black is printed first a
extra 2-3% TVI is expected.
Neg plates will be higher, but does this apply to CtP neg working, so start
from a linear base!
