Question

problems with embedding color profiles

My last print came out greenish on the final print after having sent my files to a vinyl pressing plant - they were supposed to be B&W.

 

They specifically ask you not to include a specific profile on your print and use euroscale uncoated v2, which is a rather old profile.

 

This time I decided to include GCR FOGRA27 Uncoated, as this mimics euroscale uncoated v2, but has less of a color variance and stronger K value, or so i've been told.

 

Now I got back this reply:

 

“In our specification, it is written that the files should not have any profiles added/attached.
Adding profiles to the files is pointless because after going through the repro department all profiles are removed from the file. 

 

If your customer wants to use profiles, they should apply the profile, don't attach/add it to the file. Attaching a profile doesn't change the CMYK values, it just simulates the display, and that doesn't give us anything..."

 

I don't know what they mean by saying I have attached the profile rather than applying it, I exported the file from Illustrator as a pdf with my preferred color profile attached:

 

 

Now they are sending me previews where you can visibly see a color difference;

 

 

It's subtle, but below is my version via overprint preview using the GCR 26 uncoated profile, vs their preview, which is slightly green when viewed through the euroscale uncoated v2 overprint preview that they are using...

 

All I want is for my record to be printed as intended, and not to come out slightly greenish again... Can someone help me here? 

 

Best

They do not want you to assign a profile. 

 

 

File >> Document Color Mode >> CMYK

Edit >> Color settings

 

 

Then for your PDf generate using Illustrator Default, so you have no profile.

Alternative:

Keep color management turned on. And have it (and the document) set up with the profiles the company uses.

When exporting the PDF: in Output: No Conversion, no profiles.

Thank you both for your answers;

 

Monika you make a fair point, and in theory I could just export it in their preferred profile 'Euroscale Uncoated v2'. Though as mentioned, i've done this in the past and sadly the record came out slightly greenish.

 

Someone on this forum recommended using 'GCR FOGRA29 uncoated' as it's close to Euroscale yet has a better performance with maintaining the image B&W. Though then I got this strange answer from them, regarding applying a profile vs attaching it...

 

Here are my color settings:

 

 

 

You've seen my export window, it's fogra 29 all the way.

 

Say I now wanted to do 'Euroscale uncoated v2' as you mentioned via my color management profile, to set up my file via the profile the company uses, well, I can't select Euroscale v2 from the color management selection grid;

 

I can, however, Assign the 'Euroscale v2 uncoated' profile:

 

Then export as such:

 

 

Though, as mentioned prior, my image came out slightly off color (greenish, and this isn't the first I've had this problem with them) after following these steps the last time. 

 

Long story short. I've followed your steps and when exporting, (though instead of changing the profile via color management, I assigned the profile), and now the image looks fine. Though when doing a quick 'output preview' via Adobe Acrobat, I am previewing a reddish image instead of a B&W one:

 

 

Is this cause for concern? The only mistake I can think of is that I edited the image in Ps using a different profile. But doesn't the assigned profile in Ai, (in this case Euroscale uncoated v2) override that Profile I exported the PS PDF in (FOGRA29), which I then added into Ai?

So that image is in which color space?

What you can do in Photoshop is "Convert to profile". I would assume that this is what they mean. 

But if this print is supposed to be b&w, I would make that I use a greyscale image in it.
