Thank you, and sorry about the html. I know better. It is as I thought about the fonts. I don't mind exporting them as curves. The only drawback is that the "text" in the resulting pdf cannot be indexed for my search engine to pick up, unless I use OCR to add a text layer afterward. But actually most of the fonts I routinely use are not displayed in PDF Studio, and I really don't have time to track down all their irregularities, so I'll just live with the problem. Really, the only reason I use PDF Studio is for its imposition capabilities. I find PDF X-Change to be a better pdf editor, even though I have to run it under Wine, but it lacks imposition tools. -------------- next part -------------- An HTML attachment was scrubbed...
