- Thread-topic: Adobe Acrobat | Extracting files and norm ICC profiles.
Hello Refik.
I used Enfocus PitStop Pro and callas pdfToolbox.
Both indicate the proper RGB ICC profile embedded with the imported image.
I also succeeded to export it with the latter, which is impossible with Acrobat
Pro, so far.
Because I only obtain the ICC profile form the PDF output intent while I obtain
both with Callas.
This file has been made from a joboption I gave to our external agency in which
no color conversion is requested.
The only CMYK information relies in the Output Intent profile Name and the
Output Condition Name to perform proper transformation later in our prepress
server.
The truth lies elsewhere.
Best.
Axel

Dear Axel,
Can you check what each image has been tagged with before exporting them to
Photoshop from PDF? You can put "Output Preview" into "Object Inspector"
Preview mode (instead of its default Separation Preview mode) and click on each
image to see the color mode as well as the tagged profile.
As a PDF/X-4 file is being exported, you either choose to do no color
conversion or to convert to a destination profile which also becomes the Output
Intent. When you choose to have no color conversion, the image files retain
their original color mode and profile (if they have been already tagged before
they are placed in InDesign). Just grab a couple of RGB images each tagged with
a different ICC profile. Place them in an InDesign file and export the page as
a PDF/X-4 file by choosing "No Color Conversion" with any CMYK profile chosen
as the Output intent, say ISO Coated v2 (ECI).
When you check the images with the "Object Inspector" tool provided by the
"Output Preview" pane, you will see that all images are in their original color
mode tagged with the original RGB profile.
When you export the page to PDF/X-4 by choosing "Convert to Destination", you
will see that your images have all become untagged CMYK files. When
individually exported to Photoshop, they will open as untagged CMYK files. But
you know what the CMYK profile is; it is the Output Intent.
In the last scenario, when you place untagged RGB files in an InDesign document
and export it as PDF/X-4,
the image files become tagged with the RGB working space set in the color
settings of InDesign.
So, what is happening at the end of the process when you export the image files
from the PDF, pretty much depends on how the PDF/X-4 file has been exported to
PDF from InDesign in the first place.
Best Regards,
Refik

Subject: Adobe Acrobat | Extracting files and norm ICC profiles.
Dear community,
I was wondering if someone already experienced this behavior or should
explain what happens.
I exported images from a pdf/x-4 with an RGB ICC profiles tagged on it.
I used the internal export tool function to export them and then open in
them in Photoshop.
I expected to obtain the same one.
But I have been surprised to see it wasn't the case.
The image has been made with an sRGB ICC profile.
And after having been exported, when I opened it in photoshop, it's an
eciRGB ICC profile within.
Does that mean Acrobat would overwrite the original with its own color
management preferences?
Thank you for your enlightening.
Sincerely.
