Re: CMYK spaces used for document creation



Martin,

I am pretty sure that NOBODY ever has tested an AdobeRGB->FOGRA39 DeviceLink in Photoshop CS4!
Why?
Because it doesn´t work!
CS4 isn´t able to handle RGB-CMYK DLs, as I have stated in an article I posted on this list nearly a year ago and took some bashing from Chris Cox for that. I still don´t take anything back since nothing has changed since then.


So, I agree with you, if you want to convert using DLs, you´ll have to leave Adobe´s products or use 3rd party enabling technology within Adobe´s products (e.g. basICColor demon).

I do not agree with you statement that Adobe´s CMM is inferior to any of the other CMMs.

It is very strange that nobody has commented on you comparing apples and pears. A DeviceLink is a completely different animal than a pair of device profiles. I guess that Graeme calculates his own gamut mapping in a DeviceLink, as we do, so he is independent from the gamut mapping in the device profile. The result HAS to be different, and it has to be better, if the gamut mapping strategy is better that that of the profiler that created the device profile.

On http://files.me.com/basicc/ksivsq you find the conversion result of a basICColor DeviceLink, let me know, what you think.

Best regards,

Karl Koch

As I've now posted the images, profiles and method all that remains is for you to admit that I was right and converting images outside of Photoshop gives superior results.

Going back to the poor scientific mind set of yours, for the last time, I’ll paste:

And you tested the same device link in CS4?

Don't see the point?

Sure, why try the same Device link in product A and Photoshop? Why try ICC profile in product B and Photoshop? Having an apples to apples comparison might invalidate the crappy results you seek. And that doesn’t even account for the number of posts after you said you’d rather have needles in your eyes until we actually got the reality check that you were comparing ICC profiles in Photoshop to Device Links in another product. And some are taking you seriously?

You sound surprised by that?

I think that a veteran repro guy who spends all day working on colour conversions who says "I get better results with product x" should be taken seriously on this forum.

Certainly more seriously than somebody with no comparable expertise or experience.

CS4's ability to apply device link profiles is a tiny little fig leaf covering the your embarrassing nakedness of CMS shortcomings.

I saw no point in testing it because the conversion itself is just about the least significant part of the "outside of Photoshop" colour conversion work.
