If You Have
Then
CT/LW files that the
CEPS JTP cannot use
Use the Translate function on the Brisque to convert
the files to a Brisque CT/LW file.
CT/LW or TIFF/IT files
that the CEPS JTP cannot
use
Use CEPSLink software or a third-party product to
convert them to PDF files or another format that
Prinergy recognizes.
For existing DCS files for which the CT/LW file is unavailable, see
on page
Using Enfocus PitStop to change color recipes
Enfocus PitStop handles CT and LW layers differently when you use it
to change color recipes in PDF files. For CT layers, Enfocus PitStop
displays only the color of the current selection; you can make color
retouches to the layer, but you can't change the color recipe. For LW
layers, Enfocus PitStop displays both the source and target color, so
you can change the color recipe. For more information, see the Enfocus
PitStop documentation.
Sample recommendations for processing CT/LW
These are sample recommendations for RIPing CT/LW through
Prinergy to a 2400 dpi device.
Option
Advantages
Potential Drawbacks
When to Use
RIP: LW resolution =
2400.0 dpi (94.48819
dpm)
Reduces the potential
to introduce artifacts
None if page is RIPed to
correct resolution. May
result in very slight image
quality degradation if
resampling at conversion
stage.
Always (recommended)
RIP: CT resolution =
300.0 dpi
Reduces the potential
to introduce artifacts
