What are the common things that
can be found in Chroma Graphics's CtP workflows? Besides
using the same vendor Kodak, speed and reliability of
the rasterizing machine is what we are looking for.
Currently, we run 2 major CtP workflows
from Kodak namely the Brisque and Prinergy. Both are
capable of generating a 1 Bit Tiff but the RIPs are
not connected directly to our Plate Setters to ensure
that we have the least down time and also to allow the
RIP to be more productive.
With this setup, our Brisque is
able to produce 2 separate 1 Bit Tiff files at the same
time while the Prinergy Evo and EL can generate 3 separate
1 Bit Tiff files at the same time, although the Prinergy
EVO is less powerful than the Prinergy EL, it is still
one of the latest written RIP software in the Prinergy
family, until Kodak launch the new Prinergy version
3.0. So far, Prinergy EVO has proven to be able to produce
reliable normalized PDF files.
Chroma Graphics can produce and
diagnose PDF files much better because we now have both
the Brisque and the Prinergy. PDF files that are created
from Prinergy can be sent into the Brisque for analyzing
purposes and if the result is positive, it will prove
that this PDF file will be very reliable when supplied
to either our customers or the respective printers.
However, PDF files are only normalized files and do
not contain information such as DPI (dots per inch)
or LPI (lines per inch). Ultimately, the printer has
to match our CtP wet proofs that we have generated through
our Workflows, and this will depend on the power of
the printer's Ripping system and capabilities of their
workflows. Elements such as overprinting or knockouts,
even if they have been embedded in the PDFs cannot be
properly utilized if the printer is running on an older
or lower version. Hence, that will present a problem
during printing in their bids and efforts to match our
CtP wet proofs.
Prinergy EL is the latest product
that Chroma Graphics has purchased. It contains 2 servers,
the main server (4 CPUs) and the Rendering Station (2
CPUs). When they are in action, it will utilize the
full resources of both systems (6 CPUs) in normalizing
and rendering of the high res 1 Bit Tiff files. Printers
can also match our CtP wet proofs with ease now with
our new systems but will still be subjected to the same
version and capability of their Workflow.
Apart from being able to speed
up the Ripping, the EL is also able to perform Versioning
that is gradually growing in demand, especially for
co - edition projects. We can now combine and produce
a co-edition PDF that we use to plot on our Thermal
plates and make CtP Wet Proofs. This system also further
enhances the WYSIWYG concept (What You See Is What You
Get).
This versioned PDF can also be
used to output Docucolor Digital proofs, which is the
last stage of production to ensure that the CDs or DVDs
containing these final PDF files have been security
checked.
All 3 RIPs hold their own queue
lines and are able to perform basic functions like trapping
and even impositioning. Chroma Graphics is now able
to hold our own fort and will have greater computing
power with full technical support from our System which
is now far more superior and very reliable.
Technical Performance of
the System is basically configured as follows:
| Technical Performance
of the System is basically configured as follows: |

4
inputs (PS /PDFs) and 2 outputs (1 Bit Tiff) |

1 input (PS /

3 inputs (PS /PDFs)
and 2 outputs (1 Bit Tiff) |
IMPORTANT NOTICE
Despite our efforts, the continued
research and installation of the most advanced and high
performance equipment by Chroma Graphics, it is still
important that respective printers who work with us
using our systematic and well structured PDF files,
have to ensure that their system is comparable and compatible
to the current workflow demands. It is beyond Chroma
Graphics control if problems on press occur because
of technical incapacity on their system.
