In Microsoft Office Publisher 2007 and in Microsoft Office Publisher 2003, when you export a picture that uses the Tagged Image File Format (TIFF), the exported picture uses the red-green-blue (RGB) color model. Additionally, an alpha channel is added to the image data of the exported picture. This behavior occurs even when the original picture uses the cyan-magenta-yellow-black (CMYK) color model and does not have an alpha channel.
This problem occurs when you export the picture by using either of the following two methods:
If you have to edit an embedded CMYK image, you must obtain a copy of the original graphic and then work with that image. If the original graphic is unavailable, open the picture in a photo editing program (such as Adobe Photoshop) after you export the picture from Publisher, and then convert the picture back to CMYK.
In Publisher, there are two methods for converting an embedded graphic in an external graphic file (besides copying and pasting). Both of these methods work well when you have to convert an embedded RGB picture to CMYK.
