title: MATLAB: print pdf in black/white
body: <p>Matlab prints figures in either black/white or color. A black/white print of a figure is NOT the same as a color print tweaked to black/white: <em>every</em> color including the light ones is translated as black. (Light colors that look good on screen or a color printer look horrible on a black/white printer)</p>
  
  <p>I would like to print a PDF file of a figure. My problem is that there doesn't seem to be a PDF driver for MATLAB that outputs black/white rather than color.</p>
  
  <p>See the <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/print.html" rel="nofollow noreferrer">print</a> command: <code>-dpdf</code> is the PDF driver but it is color.</p>
  
  <p>Is there any way I can do this?</p>
  
  <p>(edit: <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/creating_plots/f3-84337.html#f3-99776" rel="nofollow noreferrer">http://www.mathworks.com/access/helpdesk/help/techdoc/creating_plots/f3-84337.html#f3-99776</a> shows the interactive way of doing this, but I need a programmatic method, otherwise it will get tedious rather quickly.)</p>
