How do I change colour profile of embedded objects?

Mar 7, 2013 5:04 AM

One of my Illustrator CS6 documents was intially created some time ago without paying much attention to colour management issues. I am now trying to put that right and have assigned the document a profile of Adobe RGB (i998). However, each time I open it I am warned that 'The document has an embedded color profile that does not match the current RGB working space'. It also says that the embedded profile is sRGB, while my working space is Adobe RGB. I get this message three times and am assuming that it refers to embedded objects.

 

So far, I have failed to find a permanent solution. Do I have to reimport all items that may have a colour profile, having first ensured that they are tagged as AdobeRGB?

    Are linked files in the document?

     

    It doesn't make sense to just tag a pixel image diffrently, because that might change its look dramatically. The color profile describes what you had in mind when you created that image resp. in case of photos how the camera sees color.

     

    In case you ant to change that afterwards you need to convert the image into the other profile. But why do you think you would need that? For most semiprofessional cameras sRGB as a color profile makes absolute sense.

     

    When designing stuff for the web, sRGB as a working profile makes sense as well.

    Hi Monika,
    First of all, let me apologise for using the word 'embedded' instead of 'linked'. I was distracted by the fact that the doc in question (an award certificate) is embedded in a Microsoft Access report. That being said, I have now found that all the linked logo images in this Illustrator doc are GIFs or TIFs that don't accept a colour profile (and thus cannot be the trigger for my profile warnings).

     

    I use a Canon 5D and (rightly or wrongly) have chosen to standardise on a CS working space of Adobe RGB. However, your reference to digital photos is not relevant in this case as there are none in the document. My only concern is to make this document match my working space and no longer trigger irritating profile mismatch warnings. My overall objective is to ensure that the colours will all be correct when it goes to a printer (one of our sponsors, a UK colour paper manufacturer, will be printing the final certificates from a PDF file).

    Those .gif and .tiff files RGB color?  The certificate is going to be printed offset?  Illustrator warning happens as a default even when tags fall in line.  Somewhat bothersome, they do serve a purpose.  I think you are on the right track, though.  But, if those files are color files, it may benefit you to reassign Adobe RGB to a copy of the original file(s); then convert them to CMYK in whatever your printer is asking for ( profile, that is ).  Place the CMYK files into a CMYK document to be printed.  By creating an Adobe RGB file, you open up the gamut a little more in line with CMYK conversion characteristics.  You could convert the sRGB, but those may be clipped and will limit the accuracy of the color itself.

    John,
    These certificates will be printed on a professional inkjet printer using RIP software. My understanding is that RGB is appropriate for this.

     

    All the GIFs and TIFs are also RGB.
