Repeating a 3 x 2.5 image

If emka.pdf is the PDF file that contains the business card, you can do

\documentclass{article}
\usepackage[
  paperwidth=8in,   %???
  paperheight=13in, %???
  textwidth=6in,
  textheight=12.5in
]{geometry}
\usepackage{graphicx}
\newcommand{\putpic}{%
  \includegraphics{emka.pdf}\includegraphics{emka.pdf}\par}

\begin{document}
\setlength{\parindent}{0pt}
\offinterlineskip
\putpic
\putpic
\putpic
\putpic
\putpic
\end{document}

Set the precise dimensions of your paper; five rows won't fit on Letter or A4 paper.

I put a 1ex gap between images, which can be changed with the \myhgap definition and \myvgap. The size of the graphic is immaterial to the approach, except insofar as you have enough margin to contain them.

EDITED to center result vertically and horizontally on page.

REDITED to provide registration marks for cutting. Also, cleaned up code, for proper vertical spacing.
