GCR, GCR plus and UCR

Onyx Version:
PH 10.2.5/Thrive 11.1
Printer(s):
EVO33, mimaki jv4-180

Been awhile since I've posted here.
I'm having some new issues with a brand new printer and hoped maybe someone could interject...We've upgraded from our Scitex to an EVO33. One of the main benefits is our shop is now 100% solvent free! Yay! The printer shipped with Caldera and the MFR flew me to their facility to train. They pushed Caldera on me for several days, and I have to say, that is what I'm having to run for the time being. I've built 3 different profiles in Thrive, and none are useable, which makes me really sad.
I'm getting decent spots, but am having some major issues in the shadows...I just can't get it to give me nice rich shadows, the UCR and GCR (and GCR plus) are giving me fits...no matter what I try, the blacks keeps coming in as key-ish, but I need rich shadows to roll with Onyx.
This is really killing us, because our workflow with Onyx has been absolutely great since we've icc profiled. Caldera has weak spot color tools, so I am kind of free floating until I can get my Thrive running correctly.
I know there are dozens of factors that can be giving me this problem, but I feel I've exploited about every one of them I can...
Any advice?
Thanks!
Andy

Andy,

This is almost certainly not caused by your black generation strategy, but by your ink limit combinations.

One key difference between Onyx and Caldera is that while Onyx actually gives you several methods for controlling your ink limits -- beginning to end -- Caldera only gives you one.

The problem is that the one that Caldera gives you will oftentimes give you a result such as you're seeing with Caldera, while the one Onyx pushes can give you results like you're seeing with Onyx.

However, the tools are within Onyx to do an actual better job than Caldera -- up until the ICC profile itself -- which is what the RIP actually controls. It just takes some real skill and experience to know how to use them.

Also, while Caldera includes in Easy Media a version of the best ICC profile-building engine out there, it's something of a dumbed-down version, and missing some pretty important features.

That's why it does take following a certain path, but the best possible color there is is still achievable with Onyx, pretty much regardless of machine, or process.

We are doing dye sub, and I'm finding the ink seems better suited for direct to media. I think the Onyx driver for my machine was poorly executed, but I have been giving it my all. I have built several profiles with delta e's under 2...one of the at 1.6...so I'm having a hard time thinking I was just lucky.
Another difference is that I built the profiles in Production House 10, and have yet to get great success through Thrive. I noticed there is definitely a distinct "caldera" flavor and a distinct "onyx" flavor in the profiles I've created. I was kicking around building my spectral file in the xrite i1 profiler...and import the readings for a direct comparison. I think I may be hitting a brick wall though as I need more aperture...but am hard pressed to drop the 5 to 7 grand!!!
