Hi Axel,

I try to keep myself short. 

We have worked with it as “exchange space” in form of an output intent with the target to print on wide gamut CMYK and CMYK+ printing devices.

We did not convert any RGB images into this “artificial” colorspace. For rendering the DFE's where instructed to honor the OI, hence the RGB images got converted to the devices color space via eciCMYK.

The results where very promising. However, you will never get a a color proof that resembles the final print if the printing devices do not match the colorspace of eciCMYK for each colorant.

On the other hand I do not recommend to use eciCMYK as substitute for PSO coated v3 or ISO coated v2 when working converting images from RGB to CMYK as this CMYK images have to get converted before output. They are not intended for printing without any further conversion.
If the target is offset printing (or with the intention, that digital an offset print has to look alike), then I recommend to stay with the current ECI profiles for this printing condition. eciCMYK does not help. It would even make things more complicated.
If someone used such converted CMYK images in a common prepress workflow, these images would get placed in InDesign and exported to PDF defined in DeviceCMYK, without any conversion (CMYK profiles get discarded by default for good reasons). Someone could argue that in such a case the CMYK source profile has to get honoured. As we all know, such a method works in theory, but not in practise.

I am not going to discuss this topic any further at this point. It is a topic that is better discussed with some glasses of red wine at hand.

If you want to keep images media neutral, keep them in ICC based RGB and create a PDF with ISO coated v2 or PSO uncoated (or any other output intent that fits the required printing condition)

Dear all,
 
I read a lot of discussions in several forums about the F53 CMYK working space presented by FOGRA.
But, until now, I did not saw anything in the real life production.
 
I know it’s often difficult to change attitudes and even more habits.
 
Nevertheless, I was wondering if this ICC profile could be considered and used in a almost certain Media Neutral Workflow like the one used in RGB?
 
After all, it could be maybe easier for non-specialist Creative Agencies to give a PDF “neutral” CMYK rather than very exotic.

What do you think about it?
 
Best,
Axel
