Suppose that you have a Pro class fonts such as Adobe Arno which has several design sizes as described below:

Design    Size  Size Ranges             

Caption:   8    point 5–8.5 point

SmText:   10    point 8.6–11

Regular:  12    point 11.1–14 point

Subhead:  18    point 14.1–21.5 point

Display:  36    point 21.5+ point

Arno Pro is supplied as set of the following font files:

ArnoPro-Bold.otf

ArnoPro-BoldCaption.otf

ArnoPro-BoldDisplay.otf

ArnoPro-BoldItalic.otf

ArnoPro-BoldItalicCaption.otf

ArnoPro-BoldItalicDisplay.otf

ArnoPro-BoldItalicSmText.otf

ArnoPro-BoldItalicSubhead.otf

ArnoPro-BoldSmText.otf

ArnoPro-BoldSubhead.otf

ArnoPro-Caption.otf

ArnoPro-Display.otf

ArnoPro-Italic.otf

ArnoPro-ItalicCaption.otf

ArnoPro-ItalicDisplay.otf

ArnoPro-ItalicSmText.otf

ArnoPro-ItalicSubhead.otf

ArnoPro-LightDisplay.otf

ArnoPro-LightItalicDisplay.otf

ArnoPro-Regular.otf

ArnoPro-Smbd.otf

ArnoPro-SmbdCaption.otf

ArnoPro-SmbdDisplay.otf

ArnoPro-SmbdItalic.otf

ArnoPro-SmbdItalicCaption.otf

ArnoPro-SmbdItalicDisplay.otf

ArnoPro-SmbdItalicSmText.otf

ArnoPro-SmbdItalicSubhead.otf

ArnoPro-SmbdSmText.otf

ArnoPro-SmbdSubhead.otf

ArnoPro-SmText.otf

ArnoPro-Subhead.otf

How should one setup fontspec
package to exploit best features of these fonts?

Starting code is here:

usepackage{fontspec}

setmainfont[Renderer=Basic,Ligatures={TeX}]{ArnoPro}

Would it be sufficient? I am not sure that Caption version of these fonts will be invoked by the small or footnotesize switches. What should one add here?

I mean that in standard LaTeX classes font size declarations are bounded to optical sizes according to the following table:

 declaration  class option  10pt      11pt       12pt



 tiny                        5pt       6pt        6pt

 scriptsize                  7pt       8pt        8pt

 footnotesize                8pt       9pt       10pt

 small                       9pt      10pt       11pt

 normalsize                 10pt      11pt       12pt

 large                      12pt      12pt       14pt

 Large                      14pt      14pt       17pt

 LARGE                      17pt      17pt       20pt

 huge                       20pt      20pt       25pt

 Huge                       25pt      25pt       25pt

Hence, for 10pt class option, tiny, scriptsize, footnotesize should switch to Arno Pro Caption, small, normalsize to Arno Pro SmText, large and Large to Arno Pro, LARGE and huge to Arno Pro Subhead, and Huge to Arno Pro Display. All these fonts are actually diffrent, when scaled to same size, so that Caption version looks better for footnosize than Regular vesrion.

Answer to my question occurred to be rather simple. There is no need to invent sophisticated font loading procedure. fontspec package occurred to be smart enough to select correct font shape for every size. To check that one need to run the following simple test:

documentclass{article}

usepackage{fontspec}

defaultfontfeatures{Ligatures={TeX}}

setmainfont{Arno Pro}



begin{document}%

newcommand{MyText}{No offence meant, I even upvoted your answer.}



verb|tiny|=tinyMyTextpar

verb|scriptsize|=scriptsizeMyTextpar

verb|footnotesize|=footnotesizeMyTextpar

verb|normalsize|=normalsizeMyTextpar

verb|large|=largeMyTextpar

verb|Large|=LargeMyTextpar

verb|LARGE|=LARGEMyTextpar

verb|huge|=hugeMyTextpar

verb|Huge|=HugeMyTextpar



end{document}

Then I exported the compiled PDF to MS World and saw that tiny scriptsize and footnotesize are typed by Arno Pro Caption as it should be, and normalsize is typed by Arno Pro SmText as expected, e.c.t.

Great!

Unfortunately, LuaLaTeX on my computer [Version beta-0.70.1-2011052811 (rev 4277) (format=lualatex 2011.6.23)] did not manage to compile that short example, but XeLaTeX have that done very quickly.

it also works with lualatex but it takes a lot of time for luatex to create the cache for the font files:

...

nopro-display.lua)(save: /home/voss/.texlive2011/texmf-var/luatex-cache/generic

I used current TeXLive2011 pretest:

voss@shania:~/Documents> lualatex -v

This is LuaTeX, Version beta-0.70.1-2011061410 (rev 4277)

I've used the approach of simply inserting setmainfont{Arno Pro}[Numbers={Lowercase,Proportional}] for years to load Arno Pro, and it almost always works perfectly. But I've been using Overleaf lately, which requires loading fonts from a local project, plus I wanted to use the Light weights for especially large text in a particular document, so I came up with this to specify the exact ranges and names of the optical sizes. Here, the optical sizes are taken from the Adobe specimen book for Arno Pro, but using the Light Display weight for type above 36pt is my judgement:

setmainfont{ArnoPro}[

  % Path = {./fonts/}, % use to load from a `fonts` folder in your project
