Question in-RIP spot color matching improvement vs GM Colorpicker/Colorlogic Colorant

What are you trying to achieve?

colorant does not iterate a profile.
It corrects measurement data and modifies measurement data if you’re changing your ink colours in your press. For example if you change out cyan for reflex blue. You just tell it to replace cyan with the LAB value of reflex blue and it’ll do it’s calculations and change the values in your measurement data to simulate reflex blue in your press. you would have to create a profile from
The data using colorlogic copra or another profiling software.

 

Okay i see what you're trying to do.
Do you have colorant? if so, try and see if it works for you?
i haven't really played with that feature so i can't really give info on it.
But the way i do this is i build the best profile i can.

i'll use onyx swatchbooks to hit spot colours more closely as it's so much easier then trying to add them into your profile.
and if your file has a spot colour channel, onyx will pick it up and make changes if spot colour replacement table is "on"
it's a lot easier that way, and you can manage the spot colours separate from your profile.

 

Are you sure it's not overkill for what you're doing?
what RIP are you using?

 

What software are you using to create icc profiles?

 

okay i'm not to familiar with that RIP and the profile quality.

There's a lot of different way as you've pointed out.
I personally use onyx's swatchbooks. print off a patch set, measure and find the closest match and save it. and it's always there.

I have colorant, but never put all the features to use.
i also have i1 profiler, i tried the iteration process but didn't see much of a difference.
and in onyx, it now has an iteration process and that too, i didn't find much of a difference.

It comes down to how you make the profile too though.

I can't give you a proper answer to which way is better. You'd need to test them out yourself (if you have access to the software) and i dont think many or anyone can give you the answer.

Although i have wanted to print a bunch of pantone colours and see how close they are to my current profiles. And to play with colorant more and have a look at all the features, but we've been far to busy to do that. That's why the quickest method works well for us (onyx swatchbooks)

 

Ahh, so i wouldn't call onyx swatchbooks an "iterating" method. as it doesn't update the profile.
BUT - Onyx since x18 has an iterating step after creating an ICC profile to gain further accuracy.

I'll need to set some time to have a look at colorant colour editor, i've had a look at most of the other features.
