I recently started using Acrobat 9. There is 2 things I'm looking in V9.

1- Overprint Preview
2- All image resolutions in a HiRes pdf. I see a custom check profile called "resolution of color & grayscale images is between..." but I want image resolution is ...
3- Flag any RGB images used.

Thank You ;-)

You can build a preflight check for that, is that what you are looking for?

Thanks Matt. One more question. What is the difference between ICC RGB & Device RGB?

nellbern,

ICC RGB (actually ICCbasedRGB) means that the RGB color is percisely defined by an ICC profile.

It is similar to RGB images with attached ICC profile.

ICCbasedRGB is needed to get a correct color preview and to perform correct color conversion to CMYK.

DeviceRGB is RGB without any source ICC profile. Comes mostly out of office applications. If you need to convert it to CMYK you have to guess the source profile (hence sRGB is a very good guess).
