It is not quite clear what exactly do you want to do. Usually the title is created by using \maketitle
at the point of the document where you want to insert it. However it will be formatted whichever way your documentclass defines it. Redefining it is, of course, possible: you have to define \@maketitle
appropriately, in which you can refer to \@title
, etc.
However if you are not writing your own class, there might not be much of a point doing this. If you just want a title page, you don't have to use the \title
etc commands, just put in the title whichever way you want. There is also a \begin{titlepage}
- \end{titlepage}
environment for creating a custom titlepage, but again, it does not use the \title
command.
EDIT:
Yet another indirect option (along the lines of Andrea R's solution): define your own \thedate
, \thetitle
, etc commands using \newcommand
, and then just use it in the titlepage:
\newcommand{\thedate}{\today}
\newcommand{\thetitle}{Your title}
...
\begin{titlepage}
\centering\textbf{\thetitle}
\end{titlepage}
