Unspecified trapping where black text appears
on a lighter background can produce a halo.
Scan line art such as logos, type or
illustrations at a minimum of 600 dpi,
up to 1200, to capture sharp edges.
Then straighten it, clean it and scale it
down to 600 dpi at final size.
To trap or not to trap?
The Kodak NexPress digital production
color press offers excellent registration,
both front to back and color to color.
The RIP can perform autotrapping of
all files and can be set up to overprint
all black elements. To ensure the best
quality for your document, turn off any
trapping commands in the page
layout program.
There are, however, some instances
where certain types of trapping can
enhance your design for production.
When black text or line art appears
on a light tint, sometimes a slight halo
effect will appear at the edges of the
black. One way to correct this is to set
your black to overprint the specified tint
within the layout application. By doing
so, the black will not knock out the
background tint and this will minimize
the halo effect. If you decide to do your
own trapping, please be sure to alert
your printer!
Line art scanned at 600 dpi to 1200, straightened
and then saved for 600 dpi at final size.
Line art scanned at lower resolutions may not be
crisp enough to take advantage of the high-quality
capabilities of digital printing.
Specified trapping with the same art set
to overprint black on the red background
eliminates the halo.
