Color Management for PDFs in Acrobat

Question

I'm preparing a PDF where all images are in AdobeRGB(98)
but without embedded profiles.
The global Output Intent is AdobeRGB(98).
1. Is this Output Intent profile embedded ?
My standard settings in Acrobat Professional 7 are:
RGB: sRGB
CMYK: ISOCoated
Gray: Black Ink ISO Coated
Output Intent overrides working spaces (checked)
In my environment the images are shown correctly,
which means that sRGB is replaced by AdobeRGB(98).
What happens for average users who have only the free
Acrobat Reader ?
2. Is there any Color Management in 'Reader' ?

Gernot,<br /><br />"1. Is this Output Intent profile embedded ?"<br /><br />In this particular PDF, the answer is 'yes'.<br /><br />I Opened the PDF with a demo of PDFCanopener and I saw, inside the DestOutputprofile:<br /><br /><pre><br /><code><br />Cos Type: Stream<br />Indirect Object:<br />    ID: 953<br />    Generation: 0<br />Stream Bytes: 281<br />Decoded Bytes: 560<br />Encoding:  PDFText<br /><br /><Start Stream><br />0ADBEmntrRGB XYZ Ï<br />acspAPPLnone<br />öÖÓ-ADBE<br /><br /><br />cprtü2desc0kwtpt<br />bkpt°rTRCÄ<br />gTRCÔbTRCärXYZô<br />gXYZbXYZ<br />textCopyright 1999 Adobe Systems Incorporated<br />descAdobe RGB (1998)<br /><br /><br />XYZ óQÌXYZ <br />curv3curv3<br />curv3XYZ <br />O¥üXYZ 4 ,XYZ &1/¾<br /><End Stream><br /></code><br /></pre><br /><br />And PitStop can extract the profile.<br /><br />If you open picture by picture with Photoshop, no one has an ICC profile assigned. Same in Acrobat-PitStop: Plain RGB with no profile.<br /><br />Hope this answers question(1).<br /><br />PS. I inserted some carriage returns in the code as it seems to defile the forum display.
