To lig or not to lig? That is the question.
When should I use ligatures and when should I not?
I know that for formal publications it is generally accepted that you should use ligatures …
But for ads, flyers, biz cards??????
Any thoughts??
Regarding Sii's comment that OpenType fonts are "better"
because ligatures are placed automatically.
Fonts are inert objects. Ligatures are placed by applications
that use fonts. The only responsibility of a font is to
store enough information so that applications can work
with ligatures. Type 1 and truetype fonts can both store
ligatures. In the AFM files of type 1 fonts, one can store
additional information that may help applications with
automatic ligature subsitution and placement of ligatures
on the page. The famous GPOS and GSUB tables in OpenType
can be introduced in truetype fonts as well--there is nothing
that ties these tables umbilically to OpenType.
So, how exactly are OpenType fonts better?
> InDesign and better fonts
Luc, nice to see you here again. You may have missed my point, I said InDesign and OpenType fonts provide an automatic solution. By better fonts I meant OpenType fonts with more ligatures (mapped using GSUB) than your typical Type 1 font. As opposed to same OpenType fonts with the same number of ligs as your typical Type 1 font.
Theoretically someone could write a page layout app that would do a good job with sets of Type 1 or regular TrueType fonts (perhaps referencing an online database mapping the expert sets in some kind of virtual GSUB). But is seems like an awful lot of work when OpenType provides all the information an app needs.
Cheers, Si
Hi Dan-- Wie gehts?
You are right that GPOS and GSUB are typical tables in
TrueType flavored OpenType fonts. But they can be found
in many blue-blooded TrueType fonts as well. These are
mostly for Arabic scripts where positioning and replacement
are crucial.
Thanks to google's capability of opening binary files such
as TrueType files, you can find examples of such fonts by
a simple search such as
filetype:ttf GSUB
I do not wish to hijack this thread though.
All the best and see you soon,
Luc
Luc is correct here - GSUB and GPOS predate OpenType by several years, and were used in shipping Arabic fonts before OpenType.
See the "TrueType Open" Spec posted here...

OpenType was positioned as "TrueType Open version 2".
