(that would be a font size of, for example, 10. points).

The attached is not a large font size, but it is a randomly chosen PDF

Looks clean to me.

I don't see any essential difference between an enlarge version of a small

  Thank you, Les. I've forwarded your message to the fellow who asked the
question. It seems to me that a PostScript font can be scaled to any desired
size since it's an outline rather than bit-mapped.

All typographers and font designers routinely complain that bigger font   
scaled up font (and viceversa), because the typeface features must be manually 
adjusted to convey the same look in different sizes. However, I doubt that 
considerations of typographic beauty play a a large role when making a poster.

Stefano,

  What started this is the use of a Web browser for display of presentation
visuals by one of the local computer professionals. He apparently likes to
have only a few words (6, apparently) per slide and in a very large size.
He cannot write the text using OO.o and have the resulting huge text look
smooth at those sizes. I suggested he consider using the beamer class in
LyX/LaTeX, but he is interested only in generating anti-aliased huge
characters for his browser-based presentation. I think that as long at the
edges look smooth he'll be happy.

Thanks,

Rich

Thank you, Les. I've forwarded your message to the fellow who asked the
 question. It seems to me that a PostScript font can be scaled to any
 desired size since it's an outline rather than bit-mapped.

 Much appreciated,

 Rich

Stefano,

  What started this is the use of a Web browser for display of presentation
visuals by one of the local computer professionals. He apparently likes to
have only a few words (6, apparently) per slide and in a very large size.
He cannot write the text using OO.o and have the resulting huge text look
smooth at those sizes. I suggested he consider using the beamer class in
LyX/LaTeX, but he is interested only in generating anti-aliased huge
characters for his browser-based presentation. I think that as long at the
edges look smooth he'll be happy.

Thanks,

Rich

Maximum Font Size

[Rich Shepard]

  Someone local has developed his own solution for preparing and displaying
slides during presentations. He uses a browser for the display and type size
of 60pt-120pt. I mentioned that I use the Beamer class with whatever the
default type size is and the results are readable in all room sizes in which
I've been.

  But, he asked if LaTeX (or TeX itself) can scale type to 60-120pt and have
it look as smooth as smaller sizes. I've never done this, nor am I sure just
how to go about testing whether it can be done, so I'm asking here. I have a
vague recollection of reading about using LaTeX to prepare posters or
banners, but that was a while ago and I may well be mistaken.

  Could such large type sizes be cleaning rendered by TeX?

Rich

The attached is not a large font size, but it is a randomly chosen PDF 
generated from LyX, enlarged in Acrobat Reader to 2400%.

Looks clean to me.

I don't see any essential difference between an enlarge version of a small 
font, and a large font.  In fact, I've generated posters very successfully by 
creating them page size, then plotting with a scale factor.
