Note: When you enable this feature, Color Matcher requires some
additional processing time because of the extra calculations involved.
Overprint Handling (CPU Intensive)
(See
on page
)
Select to prevent overprinting objects from generating
unintended knockouts.
If you are converting spots to process for a proof, or if you are
color-matching one CMYK space to another CMYK space for a
proof, you probably need to apply overprint handling, even if
you applied it during refine.
To use overprint handling, you must:
1. In the
ColorConvert
section, select:
●
The
Color Matcher
JTP
●
The
Match Colors in Page Content
check box
●
The
Overprint Handling
check box
2. Choose between raster and vector overprint handling in the
Methods
list.
Note: The raster option is available only when
Shades=256
is
selected in the
Render
section of the process template.
Method
Choose to use vector or raster overprint handling for this output
process.
Select
Raster
when outputting to low-resolution contone
proofers (for example, Veris digital proofer or Matchprint Inkjet
proofer).
Note: To use raster overprint handling, you must select, in the
Render
section of the process template,
Shades=256
.
Additional factors to consider:
●
Raster overprint handling can be applied only to continuous
tone data
●
Raster overprint handling occurs after the RIP
●
Raster processing time increases exponentially as the
resolution increases
●
Raster overprint handling eliminates all overprints
Select
Vector
when outputting to halftone (screen) proofers
(for example, the Spectrum device), or to high-resolution
contone proofers.
