Grayscale output with latex (via GS)

Postby Faust » Sun Jan 17, 2010 9:19 pm

I have been asked to supply a black/white copy of some pdf's.

I presume this is for decreased size and for those who do not own a color printer.

Anyways, I have 2 questions regarding this:

-is there a way to make grayscale pfs with pdf2latex (what command if there is)

-Im using the latex- ps- pdf route via ghostscript and added commands for grayscale output, however this is as fast as a snale in hibernation. Is there a way to speed it up? I used this:

Arguments for the ghostscript postprocessing in the profile I made:

-sPAPERSIZE=a4 -sColorConversionStrategy=Gray -dProcessColorModel=/DeviceGray -dSAFER -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile="%bm.pdf" -c save pop -f ""

it looks nice and grey though but took like 5 mins to build.

Try \selectcolormodel from the xcolor package:
  1. \documentclass{article}
  3. \usepackage{xcolor}
  5. \selectcolormodel{gray}
  7. \begin{document}
  9. \textcolor{blue}{\rule{5cm}{2cm}}
  10. \textcolor{yellow}{\rule{5cm}{2cm}}
  12. \end{document}
