4 Enter a value in the Height/Width Per-
centage text box to specify the trap on
horizontal lines as a percentage of the
trap on vertical lines.
Specifying different horizontal and ver-
tical trap values lets you compensate for
on-press irregularities, such as paper
stretch. Contact your print shop for help
in determining this value. The default
value of 100% results in the same trap
width on horizontal lines and on vertical
lines. To increase the trap thickness on
horizontal lines without changing the
vertical trap, set the Height/Width value
to greater than 100%. To decrease the
trap thickness on horizontal lines with-
out changing the vertical trap, set the
Height/Width value to less than 100%.
