Is there a way (from within Acrobat Pro 6.0.1) to determine the ppi of an image embedded in a PDF?

(I know I can extract raster images from within Acrobat and open in PS to determine ppi, or even click on raster images within Acrobat with the edit tool and open in PS. Just wondering if Acrobat has its own way of telling me.)

Thanks

Not that I’m aware of…

You may want to post this on the Acrobat forum.

They will probably let you know in a heart beat if there is a way.

Doug,

Document > Preflight

Choose to list all images then click analyse

That may get you some info you’re after.

Did it, Ron. Thanks.

Scott, do you use Acrobat a lot? Is Preflight the tool you use to find out basically what "quality" PDF you have? Whether it’s (at one extreme) a low grade, screen only file with heavily compressed and downsampled images and type or (at the other) a press-ready file with hi-rez images, only modestly compressed objects and type, and so forth, or some "quality" level in between? And if so, which Preflight profile(s) do you use for this?

I ask because I sort of expected a single place (like Document Properties) that would readily tell me things like: "This is a file saved with Press job options. It has 4, 300 ppi images in it, Adobe Caslon OpenType embedded, 7 vector objects, and a gradient mesh. It’s a CMYK file and was saved with US Prepress Defaults embedded." It seems like I have to use several different Preflight profiles to get this info… and some of it doesn’t seem to be gotten by ANY of those profiles.

Wouldn’t you sort of WANT this information, especially if you inherited the file from elsewhere and had to either design with it or (maybe more important) do prepress work on it?

I dont’ do a lot of back end PDF work anymore Doug. I pretty much just create PDFs for others. But…. for prepress info on a PDF you really, really, want PitStop Pro from Enfocus.
