I use these lines to get high quality eps and import it to LaTex documents:
First line configures figure size, I use to adjust it to the line width of the report I am creating, in order to maintain fontsize when figure is imported. (You can leave xini and yini to zero)
Second line sets fontsize and font type (use listfonts to know each font code installed in your computer).
Third line finally creates a coloured .eps file.
