JTP can be used to convert CT/LW and TIFF/IT to PDF files consisting
of two layers: continuous-tone (CT) and line work (LW).
General guidelines for using CT/LW files with Prinergy
For best results, follow these general guidelines when using CT/LW
files with Prinergy:
●
Perform as much of the page preparation as possible in the
originating workflow/RIP to reduce the potential for introducing
errors. For example, perform color conversion, including spot color
handling and overprint settings, and trapping on the Brisque before
importing CT/LW files into Prinergy.
●
Simplify the linework components for faster processing through
Prinergy. For example, try to avoid CT content in the LW file. If you
are working with TIFF/IT pages, avoid or simplify high resolution
contone (HC) components to obtain faster Prinergy processing
times.
●
If you use Kodak Full Auto Frame (FAF)/RIP templates to create
CT/LW pages in the Brisque, use a specific template to create CT/
LW output that is optimized for use with Prinergy. For example, this
template could have the resolution set to match the Prinergy output
device resolution. This output template should also RIP vignettes to
the CT layer instead of the LW layer.
●
When refining files with the CEPSConversion JTP, ensure that all the
page elements, for example, CT/ICT, LW/HC/ILW, ASSG/FP/IFP,
and so on, are available before starting the refine process in
Prinergy. If elements are missing, the refine process fails.
Preparing CT/LW and TIFF/IT files
When submitting CT/LW or TIFF/IT files to Prinergy software:
●
Ensure that files are trapped and color-matched.
●
Ensure that the CT/LW and TIFF/IT files are one of the following
file types:
○
CT/LW files generated by Brisque or PS/M
○
TIFF/IT-P1 files
●
For CT/LW files, ensure that you add the ASSG, CT, and LW files to
a Prinergy job at the same time.
●
For TIFF/IT-P1 files, ensure that you add the FP, CT, and LW files to
a Prinergy job at the same time
Note: If you are using the CEPS JTP to convert files to PDF, ensure that the input
resolution matches the desired output resolution. For example, when the desired
output is 2400 dpi, use the CEPS JTP with line work resampled to 2400 dpi.
