I need something that will convert PDFs to one-channel tiffs – each
colour separately (1 page pdf becomes four grayscale tiffs, magenta, cyan,
black, yellow). And I would like it to be just a folder that I
can drag the PDFs to and then it does its job and saves the TIFFs in
Here's how to do so on Windows:
1. Install pdf2image (http://www.pdftron.com/pdf2image/downloads.html
) and ImageMagick (http://www.imagemagick.org/download/
2. Create three directories: "input", "output_cmyk", and "output_sep".
3. Dump your PDFs into the "input" directory.
3. Run the following commands from a DOS window:
pdf2image --cmyk -f tif -o output_cmyk input/*.pdf
for %f in (output_cmyk\*.tif) do (convert %f -colorspace CMYK -separate output_sep\%~nf_%d.tif)
Now, your "output_cmyk" directory will contain the
four-channel TIFFs, and the "output_sep" directory will contain the
separated one-channel TIFFs.
