From How can I see the "implementation" of the \LaTeX command? and How to write (La)TeX (with parentheses) [or any other TeX-related logo], I learn that \LaTeX
is implemented as
L\kern -.36em{\sbox \z@ T\vbox to\ht \z@ {\hbox {\check@mathfonts \fontsize \sf@size \z@ \math@fontsfalse \selectfont A}\vss }}\kern -.15em\TeX
The \kern
parameter needs to be tweaked according to the font used, as pointed out by Knuth in a TUGboat article. When trying to change that parameter in the code above, however, I get the error ! Undefined control sequence. <argument> \z
.
How can I tweak the \kern
value of the \LaTeX
command (and of the \TeX
command)?
\documentclass{article}
\renewcommand{\LaTeX}{L\kern -.20em{\sbox \z@ T\vbox to\ht \z@ {\hbox {\check@mathfonts \fontsize \sf@size \z@ \math@fontsfalse \selectfont A}\vss }}\kern -.10em\TeX}

\LaTeX

The command being used is
\z@
, not\z
. Wrap the redefinition in\makeatletter
/\makeatother
.
