color_convert.sh + gray_to_spot.ps

./color_convert.sh black,cmyk,spot-PANTONE 705 U-0.9 0.1 0.5 0.1 input_layer1.pdf,input_layer2.pdf,input_layer3.pdf output.pdf

This will convert each input PDF file to the corresponding color mode (black, cmyk or spot color), then combine the resulting files on top of each other. dependencies: pdftk (for multistamp) + Xpdf (for pdftops)

rgb2cmyk.sh

./rgb2cmyk.sh input.pdf

This will convert a PDF to input-cmyk.pdf

If you need overprint:

./rgb2cmyk.sh input.pdf overprint

This will convert a PDF to input-cmyk-op.pdf

colorSeparation.sh

./colorSeparation.sh input-cmyk.pdf

This makes black and white images of each CMYK plates and makes a small HTML page to preview the plates. It will output blank plates if your PDF is in RGB.

Web interface for coloured preview of each plate:

By zooming out, you can see several pages at the same time:

— Each plate picture previews its color.

There seems to be a bug with Lazy Load, letting you believe your black
text is in color but it is!

Stéphanie Vilayphiouspoke

— We get rid of Lazy load which put things not in the right order.
Anyways, we consult the page locally so we don't need it so much.

Some more styling on top of the cake.

— Updated the rgb2cmyk.sh script. Now it converts an RGB PDF into a CMYK
PDF without or with overprint, with no washed colors as we've seen in
Médor 3.
Thanks to Lionel Maes (La Villa Hermosa) to have debugged this together!
