You can prevent knockout by using the
Overprint option in the Paint Style
palette to make overlapping printing
inks appear transparent.
Note: The degree of transparency
depends on the ink, paper, and printing
method used. Consult your print shop to
determine how these variables will
affect your final artwork.
You cannot preview the effects of
overprinting. On-screen, you can
approximate the colors on overprinted
objects with the Hard filter. However,
carefully check overprinted colors
on separated artwork using integral or
overlay proofs.
