Good news!! Grin


I have finally found created an acceptable profile!
What i did was i used Onyx to do the ink restrictions & calibration, read in gateway and imported to onyx.
To do the ICC, i used the i1 software, created a table, exported that to Gateway and modified that for the spectropad. printed it, read it, exported the readings to the i1 software. created the ICC. Test print and it's much much better.

Now to get it on glass.

Again, Appreciate everyone chiming in and helping me out. It was a bit of a road but i got there, not in onyx like i hoped but it's something. Smiley Smiley

Good news indeed, after some good cold sleepless nights, ha ha.

i1 software? you mean i1 profiler?

anyway, cheers for you, life with icc profile is tough.

Not sure what's the software's called but probably. I used my spectropad for the measurements and used the i1 Software/profiler to create the ICC

I still have some mucking around but I'm glad I'm there.

All I know is that onyx has some sort of flaw in the ICC engine.
Now time to make some HD profiles. Grin

Just curious here...

I just now read through all this, and maybe I missed it, but I didn't see what rendering intent you're printing to.

Mike,
that is an important question, but not in this case. I was examining a profile from Pauly, and mapping of the reds was quite strange in all cases.

All I know is that onyx has some sort of flaw in the ICC engine.
I would not say it like this. Decisions about how to generate all that thousands nodes of the look-up table in the ICC profile has no exact answer. Some ways give wonderful results in some cases but poor in others. Finding the best eye-pleasing match between distant colors is a totally fuzzy stuff.
In your case you need some more saturation... but Onyx (from my experience and tables) is after preserving hue at costs of saturation and brightness. Or maybe preserving hue and brightness at costs of saturation... (I only have analyzed a couple of profiles - maybe I´m a bit wrong...)

This is from the onyx manual

Gamut MappingCollapsed - This option determines how out of gamut colors are mapped. You can choose Classic, More LightnessCollapsed Preserving, or Enhanced Color.

Classic will attempt to preserve both Lightness (L*) and Chroma (C*) equally.
More Lightness Preserving will map the color as close as possible while preserving Lightness (L*). More Lightness Preserving is generally used for low gamut media.
Enhanced Color will map the color as close as possible while preserving Chroma (C*). Enhanced Color is recommended when more saturation/colorfulness is desired Use Large Input ProfileCollapsed Size - Enabling this option makes your ICC profile usable for proofing.

Wow! Eek!Smiley
Is this for version 12? I don´t know this. It´s an amazing feature !
In your case I would immediately go to Enhanced Color...

That's from the x11 manual online. Pretty sure this is the same on 10. as the results are the same. And I've tried them all and they're all similar. Sad
Enhanced was the worst one!! i use VIVID which isn't listed which had a similar tone to classic just slightly more vivid.
