Subject:Re: good print/online font From:"Michael A. Lewis" <lewism -at- BRANDLE -dot- COM -dot- AU> Date:Thu, 30 Oct 1997 10:06:11 +1100
Once the document has taken physical form -- and that includes bitmaps,
rasterised images, and other representations -- the fonts effectively
cease to exist. Fonts are really only used by printer drivers and screen
drivers (except for Acrobat -- see below). Postscript files are output
by printer drivers, so all the work has been done by the time the
postscript file goes anywhere else. From what I can work out, much the
same thing applies to PDF files: Acrobat puts the image together in what
I believe to be rasterised form, and font data ceases to exist. However,
I do have to emphasise that Acrobat is really a closed book to me: it
just might rasterise at print / display time, in which case it needs the
fonts on the system used for viewing. Since PDF files are meant to be
fully portable, I think that's unlikely, but I don't know for sure.
