ImageViewer Curves
The ImageViewer Curves print option lets you apply color curve edits from ImageViewer that have been saved on the
server as a preset.
ImageViewer in Command WorkStation can be used to edit the CMYK curves of a job on the Fiery ES. These curve
edits can be saved as a preset and applied to other jobs. Use the ImageViewer Curves option to select a preset for
your job.
Factory-supplied curve edits apply some typical color corrections:
•
No correction
•
Lighter highlights
•
Midtone boost
•
Shadow detail
•
Reduce C (cyan) cast
•
Reduce M (magenta) cast
•
Reduce Y (yellow) cast
After the job is processed, the edits become part of the job and are no longer visible as edits when you view the job in
ImageViewer.
Optimize RGB transparency
The Optimize RGB transparency option corrects color errors that can occur in jobs that contain transparent RGB or
Lab objects.
Optimize RGB transparency affects jobs with the following characteristics:
•
The job is in PDF format (submitted to the Fiery ES as a PDF file, not submitted by printing from an application).
•
The job contains transparent RGB or Lab objects. They might be objects that you specified as transparent using
an application that supports this capability, or they might be objects with a special effect, such as a drop shadow,
that uses transparency to achieve the effect.
•
The transparent objects overlap, creating an area of mixed color.
If you turn on Optimize RGB transparency, the Fiery ES uses the correct RGB source profile and rendering intent
when converting the overlapping RGB colors to CMYK during the PDF-to-PostScript conversion. If you turn off
Optimize RGB transparency, the area of overlapping colors might print with incorrect color or undesirable artifacts.
Optimize RGB transparency can result in a longer processing time, especially for variable data printing (VDP) jobs
that contain multiple individual PDF pages. We recommend that you turn on Optimize RGB transparency only when
necessary to achieve correct color output.
You can specify Optimize RGB transparency for a job in Job Properties in Command WorkStation, Hot Folders, or a
virtual printer.
When you print from the printer driver, the Optimize RGB transparency option does not appear because jobs printed
from the printer driver are always submitted to the Fiery ES as PostScript jobs, which are not affected by Optimize
RGB transparency.
