Ok - the Edit>Transparency Blend Space is already on CMYK.
I found the Destination profit in the output section of the export dialog. I don't recall ever setting it to anything because it's all gibberish to me. I am exporting to pdf for 2 separate purposes:
1 - as small as possible for attaching as links at a website
1 - as good as possible to send to a printing company, to make hard copy for distribution
What settings do you suggest I use?
Thank you
