Guys,
In the last two weeks I've profiled two proofing systems (Dupont WaterProof
and Fuji ColorArt, one press on two different stocks (coated/uncoated) and
three inkjet devices (a pair of Epson 10Ks and a 9600). The 9600 was a
BestColor job and the two 10Ks were Rampage ICC. This is the first few jobs
where I've started using the ECI2002 charts with PM 4.1. As always, I'm
using my trusted Spectroscan to measure the targets (feel my pain!).
As you can guess, the measuring time has just been killing me as it takes
anywhere from 1 hr. (non-UV) to 1 hr. and 10' (UV filter) to read these
charts. So the last job I decided to run both the TC3.5 (500+ patches) and
the ECI2002 charts (1500 patches) side-by-side. Know what I found? The
inkjet proof that used the ECI2002 was NO BETTER than the one using the
TC3.5 chart, in fact the proof using the TC3.5 chart was ever so slightly
smoother with less "posterization" artifacts in gradations and tonal
transitions. Now, would somebody please tell me why I need to take 4 times
as long to read a chart that gives no better and possibly inferior results?
I'm not really doubting that the ECI2002 chart is "better" but it hasn't
shown to be the case in the final results.
My own theory is that it has to do with pre-calibration and linearity. In
both systems, BestColor and Rampage ICC, you linearize the device prior to
profiling and you can even create a specific amount of builit-in dot gain
into the device prior to printing your profiling target. That's why I think
the TC3.5 chart simply works as the device is already "behaving" properly to
start with.
The ECI2002 chart sure looks impressive to a customer but for my money I'm
probably going to go back the trusted TC3.5 target and save myself HOURS of
measuring time.
Just my $.02 worth, and I could be wrong (I've been wrong once before). ;-)
