Choosing font for bold small caps (or any other particular family+series+shape combination)

I am using Aldus obtained from Adobe and installed using this method (after converting to T1 fonts): http://ftp.sun.ac.za/ftp/CTAN/fonts/metrics/w-a-schmidt/pas.txt

Using the font works fine, except Aldus does not contain a bold face and I would like LaTeX to select the bold face from Palatino, is there an easy way to do this?

EDIT: I wanted to try something along the lines of Choosing font for bold small caps (or any other particular family+series+shape combination) , but doing the following does not work:

\DeclareFontShape{T1}{pasj}{bx}{n} { <-> ssub * ppl/bx/n }{}

I guess I might be a bit naive and do not understand exactly how \DeclareFontShape works. Does there have to be a package 'pasj' for this to work? At the moment I just include the font as:

\renewcommand{\rmdefault}{pasj}

Answer 1

Using LuaTeX or XeTeX

\usepackage{fontspec}
\setmainfont[
BoldFont = PalatinoLTStd-Medium, 
BoldItalicFont = PalatinoLTStd-MediumItalic]{Aldus LT Std}

I think the bold face of Palatino is too bold for Aldus, the Medium weight is better:

Answer 2

Whereas the original Aldus font, created by Hermann Zapf in 1954, indeed only has roman (upright) and italic shapes, there is now the 'Aldus Nova' font, created by Akira Kobayashi and Hermann Zapf in 2005, that comes in the "standard" four categories (roman, italic, bold, and bold&italic). Buying "just" the bold font would set you back $79; see http://www.linotype.com/109957/Aldusnova-family.html. (I have no financial interest in the Linotype company, by the way!)

On the compatibility of Aldus and Palatino (also created by Hermann Zapf): I once read (can't remember where) that Zapf initially considered Palatino to be more of a titling font (i.e., best when used at larger font sizes) whereas Aldus was, in his opinion, better at smaller font sizes. I suppose that this opinion didn't exactly harm Palatino's success in the market for book fonts over the past 50 years, did it! Still, if you can stay with either all-Aldus or all-Palatino, you're probably better off that way.

Addendum:

If you're going to mix Aldus and Palatino, you must do something about their (slightly) different x-heights; more precisely, you should reduce the scale of the Palatino fonts appropriately. To achieve this without having to work too much on converting yet another font, I think you're best off switching from pdflatex to xelatex -- trust me, the learning curve isn't steep at all -- and issue the following commands in the preamble:

\usepackage{fontspec}
\setmainfont
[
Scale      = MatchUppercase,
BoldFont   = {Palatino Bold}, 
BoldItalicFont = {Palatino Bold Italic} %% optional
]
{Aldus LT Std Roman}

The precise names of the Palatino fonts will vary depending on the source.
