Hi to the list,
I was wondering if I could seek some advice on Best Colorproof 4.6 on
an Epson 9600.
Make sure you get the latest updates (I think service pack/ProPack 2
was the last update before version 5). Last version was 4.6.3 + ProPack
2.
I am new to this product and would like to RIP colour managed Tiffs
from Photoshop and am unsure of a suitable work flow. From my reading
of the Best manual it seems to me that Colorproof is designed as a
simulation RIP (primarily for press proofs). I would like to use it
not to simulate but to print full gamut linearized RGB colour.
No problem.
I am considereing the following process.
1. create a new queue and dataset for the desired media, resolution.
Give the dataset a name that makes sense like
"Baselin_<papertype>_<resolution>_<date>"
2. perform a base Linearization for the media.
This is the most critical step. This is where training comes in or
getting a certified BestColor installer to do this for you. The manual
may give you the mechanics of creating the baselin but it doesn't
explain how best to set per-channel limits and linearize.
3. Deactivate built in col man. and output test chart
Deactivating color management should be the FIRST step, prior to doing
the baselin. You could also add a step to determine total ink limit
(in-RIP) AFTER the baselin but BEFORE you print your profiling target.
Sometimes a little ink limiting in the RIP and then setting the final
ink limit in the profile is the way to go. In either case, you should
print a chart to determine your total ink limit at the same time you
print the profiling testchart.
4. create custom profile
5. Softproof and convert to profile in Photoshop using BPC
6. Output file using the above created dataset, with col man. off.
Does this make sense? In this case all the work is done in Photoshop
but the base lin. and ink limits for the custom profile is used.
Or
Is it better to let the RIP do the profile conversions?
If so, what happens when I send the RIP an Adobe RGB file? Does it
just convert to the paper profile set in the Advanced color man.
settings? With what intent?
You could do it either way. The one advantage of doing the conversion
in Photoshop is being able to use Black Point Compensation, somethings
Best doesn't offer plus, of course, being able to soft-proof the
results prior to printing. But the advantage of letting the RIP do the
conversion is a more streamlined workflow.
If you look at the color management settings in the RIP, you'll see
that you can select default "reference" (source) profiles for CMYK, RGB
and Lab and select the rendering intent for each. There's also
check-boxes for enabling the RIP to use embedded profiles. In that
case, the RIP only uses the selected reference profiles for untagged
data.
I can see where to load a custom profile and linearization in the
advanced color settings and also where to set the profiles for the
simulation (Reference profiles). If you don't want a simulation, do
you simply leave all the reference profiles blank, or do you set the
RGB reference profile the same as the paper profile?
No. Simply select the base linearization you created and leave color
management deactivated. It will still use the baselin and ink limits
but no profiles.
Regards,
Terry
