Quick start

This is a set of scripts to convert RGB PDFs to CMYK, while preserving pure black. At the moment it is optimized for the belgian quaterly Médor, but it aims to become more generic. Meanwhile, you can explore it and tinker with it to adapt it to your own needs.

Pre-requisites

In order for the scripts to work, make sure you have all the system-wide dependencies:

• ghostscript
• pdftops
• mutools
• pdftk
• imagemagick

Using it

Organize your PDF directory accordingly:

.
├── NonOverprint
├── Overprint
└── Scribus

• In NonOverprint, put the RGB PDF that DO need to be converted to CMYK;
• In Overprint, put the RGB PDF that DO need to be converted to CMYK, but with black overprinting;
• In Scribus, put the PDFs that DON'T need to be converted to CMYK.

Then, fill the directory with your PDFs. We prefix their names with the page numbers to make sure they are assembled in the right order, like so:

.
├── NonOverprint
│   ├── 001-002-editorial.pdf
│   └── 003-some-article.pdf
├── Overprint
│   └── 004-005-table-of-contents.pdf
└── Scribus
    └── 006-012-some-other-article.pdf

Move in this directory, and make a symbolic link to your PDFs, naming the link pdf, like so:

ln -s /path/to/your/PDF/directory/ pdf

type:

• make cmyk to generate all CMYK Pdfs.
• make pdf to assemble the individual Pdfs
• make to run the two commands above at once.
• make cahiers to generate the four 32 pages booklets.
