\section{Two-column papers, print and slides}
\subsection{A narrow paper column}
Use width=\key{\linewidth} in the local column or minipage; reduce horizontal
padding and the reserved label slot before reducing font size. A normal \key{gradtable}
can be inside a table float; a wide table* can span both paper columns.
\begin{demo}{A table fitted to an 80mm column}
\begin{minipage}{80mm}
\begin{center}
\begin{gradtable}[align=c,header align=c,width=\linewidth,preset=paper,label width=8mm,column sep=3pt,min text width=12mm,
  min graphic width=15mm]
  \gradcolumn{method}{Method}
  \gradcolumn[type=bar,mark=best,
    options={max=100,precision=1}]{score}{Score}
  \gradrow{Baseline,82.4}
  \gradrow{Proposed,91.6}
\end{gradtable}
\end{center}
\end{minipage}
\end{demo}
Use the multipage example in the preceding part for long results lists. Long mode
must be outside floats and two-column text, rather than shrinking an entire long table.

\subsection{Monochrome printing}
Use \key{preset=mono} for tables, print for individual graphics, and registered textures
for categories. Keep numeric labels and category names. Explain bold and underline
marking. Print a sample at its final scale: very fine textures may disappear.
\begin{demo}{Category shares with a matching print legend}
\gradstack[print,width=75mm,height=17pt,
  stack names={Train,Validation,Test},
  stack patterns={diagonal,dots,crosshatch},
  legend=true,segment labels=percent,precision=0]{60,25,15}
\end{demo}

\subsection{Beamer slides}
Use fewer rows, larger text and stronger contrast. Individual graphics support
\key{preset=presentation}. The following is a complete source for a separate slide:
\begin{source}
\documentclass{beamer}
\usepackage{gradbars}
\begin{document}
\begin{frame}{Progress toward the target}
\gradbarssetup{preset=presentation,width=.6\linewidth,
  max=100,precision=0,target=90}
\gradbar{82}
\end{frame}
\end{document}
\end{source}
Ordinary tables can be placed in a frame. Long mode is not a mechanism for
splitting a visual table into slides; choose the rows for each frame explicitly.
