I get a huge number of PDF files to work with, but a common problem is simple: is the resolution for the embedded pictures high enough? I can simply open the PDF files with AP and they mostly look very good, but is there any chance to check the individuell resolution of the images? The global document resolution does not help cause images can be embedded with different resolutions. Is the resolution information reliable? I'm not sure cause the the following seems also not reliable ... Also, I can check for the "Document Colour Format", if it is set to CMYK does it mean that the whole Document ist ONLY CMYK or ist ist basically CMYK but other like RGB, ... are possible? Even if the Document Colour Format say CMYK the Colour Palette says RGB. It seems that this is independent from the actually used colourspace, but if so I think it should be switched automatically to the document colour mode. If the resolution ist correct it would be perfect if the used colour space is displayed nearby. Or general: is there an alternative if this doesn't work to check the objects in the PDF for resolution and colourspace (except Acrobat)?! Thanks, as always, for any help :) Markus
