Hey there.

Another question about this hi rez pdf thing.

Lets say i do some vector art in Illustrator and save as eps and place in Quark.

Normally, the vector art is sort of resolution independent, isnt it? I mean, it is output via the imagesetter, at whatever resolution the imagesetter is set at? Or am i incorrect?

point is, i always thought vector art was "output" at a very high resolution, 2400 or whatever.

If I use hi rez pdf to the imagesetter, will it retain the very high line art resolution?

What will happen to a vector art EPS if i select the downsample to 300 menu pull-down? Will it downsample the vector art output to 300?

thanks

You do need to set a resolution when you create a document in Illustrator. That is why your "Document Setup" has:
Artboard
Printing and Export
Transparency
You should learn all about setting that stuff.

The resolution is for the flatness of the vector lines -(not flattening) which will produce "smoothness" depending on the setting and the output device.
You can get really jaggy, bitmap looking images from incorrect settings.

Yes – the vector art should output high rez. (PDF or .eps) The downsample should effect bitmap files.

Always.

No, you’re right.

Correct.

No. You cannot "downsample" a vector any more than you can tune a fish.

Those settings apply only to something with pixels in it.

On the occasional you want to produce a low-rez version, say for a comping proof when you don’t trust someone, you must distill the file then rasterize it at low-rez in Photoshop.

that is all i needed to know, thank you.

i didnt see how it could downsample a vector image, but i wanted to make sure.
