How export PDF TAC 240 % with ISOnewspaper26v4.icc?

[EmKaape]

Hello all,

i have problem with export PDF with Ink coverage max 240 %.

I have from Print producer profile ISOnewspaper26v4.icc adn i install it (Ifra ).

My Document is in Illustrator (Adobe Illustrator CC 2017 with latest updates) in CMYK and profile is FOGRA 39. I try export PDF with this ISOnewspaper26v4.icc profile but after export are in PDF still places with more TAC than 240 % (280, 265 etc).

File / save as / PDF

Preset = High quality PDF

Compatibility = Acrobat 4 (PDF 1.3)

Standard: None

Output

1) Color Conversion = Converto to Destination (Preserve numbers)

2) Destination = ISOnewspaper26v4.icc

3) Profile Inclusion Policy = Dont Include

*I export before 1 year and no problem. But now cant do it with proper PDF.

Question:

1) Is my settings ok?

2) What are your procedure? Pleas give me step by step.

It could be helpful if you were providing the .ai file in question.

And perhaps the .pdf file you created.

Can you also provide the setting in Acrobat's Output Preview?

You need to select the correct profile there. Otherwise it might read the wrong values.

Hi and thanks for your reply!

Here is AI + PDF:

If your images are already in CMYK (fogra 39), they are not touched during export (because of "preserve numbers"). Open them in Photoshop, Edit -> Convert to Profile -> Adobe RGB (use intent: Relative Colorimetric) and then again Edit -> Convert to Profile -> your required 26v4 newspaper profile (use intent: Perceptual). This is for avoidance of not recommended CMYK to CMYK conversion, always go CMYK -> RGB -> CMYK. These new CMYK images use only for newspapers (include profile, also use "newspaper" in name to be clear in future).

Better, use original RGB images (if you have them), convert them to your 26v4 newspaper profile in Photoshop (use intent: Perceptual) and use in Illustrator or InDesign.

On export, i use PDF/X-1a, zero bleeds (there is no bleed in newspaper) and Trim, Registration and Page information with Offset 3 mm (or no print marks if required by client).  Use "Output Intent Profile Name" (in this case "ISOnewspaper26v4") for correct viewing in Acrobat. Is also useful "Page Information" to include in document (if someone sends you in the future renamed PDF, to find source).

Nope, you are right that CMYK images are prevented from CMYK to CMYK conversion, but your advise is deadly wrong.

Best parctice would be to place original RGB images as linked files into Illustrator, if they are placed they become converted to the document's color space.

If that is to late, open the CMYK image in Photoshop and convert it to the final output CMYK space. Converting to RGB is nonsense as it would add more conversions into the workflow. Every conversion causes a loss of quality.

So whats easy way to export? Whats the best procedure to export from Illustrator in CMYK to PDF in TAC 240 %?

I mean its so difficult procedure open it in Photoshop and again in Illustrator.

In this project i place RGB photo (by mouse) to Ilustrator = so its change to CMYK values =  so its ok to export?

I thought I could only export Illustrator to PDF, I find it very impractical to edit it in other programs and then re-export it to Ilustrator. So what is the right thing to do?

Thank you for your patience.

Willi, agree that using the original RGB images is best (when available), see my second paragraph (but still i do not agree on your CMYK to CMYK advise - I was recommended to go through RGB, so i do).

Ed wrote he has them (RGB images, so cmyk to cmyk is irrelevant for him).

If use only Illustrator:

- set Illustrator’s Edit -> Color Settings to "ISOnewspaper26v4" for CMYK and to use "Perceptual" intent in Options (recommended by all newspapers i know):

- delete all existing bitmap images from your document and Edit -> Assign Profile "ISOnewspaper26v4" to your Illustrator document:

- now again place original RGB images back to your Illustrator document (they will be converted to "ISOnewspaper26v4" profile using "Perceptual" intent)

- export to PDF (use my settings above for example, 300 dpi as in your screenshot)

If done, be sure change Color Settings back to your normal, to prevent accidental use newspaper profile for other jobs (back to your fogra39 and Relative Colorimetric intent).

I still think better to use Photoshop for newspaper conversion for bitmaps, to see the result and possibly do some corrections (wisely, keep TAC 240 %).
