Merge separated CT/LW pages on the Brisque
Merge separated CT/LW pages on the Brisque before sending the
pages to Prinergy for processing. You can identify separated CT/LW
pages by their multiple LW files. The CEPS JTP and other products
such as CEPSLink cannot process separated CT/LW pages. To merge
separated CT/LW to composite CT/LW, use the
Merge
function on
the Brisque or PS/M before bringing the pages into Prinergy for
processing.
This function has no visible impact on final output and is recommended
for use with all separated CT/LW files.
There are two reasons why the CT/LW pages may be separated:
●
Separated PostScript going into the Brisque may cause CT/LW
pages to be separated. This is the most common cause.
●
Too many LW colors may cause CT/LW pages to be separated.
There is a limit of 64,000 colors in the NLW specification. If the
NLW is very complex, then the Brisque may have separated the CT/
LW. If you can't merge the CT/LW because of this limitation, then
you should try some of the other techniques, such as RIPing
vignettes to CT. This avoids separating the CT/LW as well as
improving output performance.
Detect excessively complex pages
There is a class of very complex pages that may still fail conversion in
the CEPS JTP. You can identify these pages by:
●
CT/LW that is separated (multiple LW files) and that fails merging
to composite on the Brisque, or
●
TIFF/IT with an HC file that cannot be opened in Kodak PressTouch
(a free download from eCentral).
There are two situations which can result in these very complex pages:
●
Complex page characteristics combined with inappropriate RIP
choices can result in these very complex pages. Choosing different
RIP settings, as outlined later in this topic, may resolve this.
●
PDF 1.4 style transparency using layered CTs can result in these
very complex pages. This can create many CT-to-CT edges. RIPing
CT-to-CT borders to CT resolution resolves this.
Unsupported types of CT/LW and TIFF/IT
If your files are not of the file types specified above—for example, if
your files are PS/2, Whisper, or Linotype-Hell—you must convert them
before Prinergy can use them.
You have the following options:
CT/LW and TIFF/IT files
