Using the wiki-to-pdf publishing pipeline

• make wiki: downloads the materials from the Unfolded wiki page and generates Unfolded.html
• make run: runs a local server on port 8000 to preview the PDF at http://localhost:8000/Unfolded.html

Tools

• PDF rendering: Paged.js (https://pagedjs.org/)
• generate HTML: update.py is used to download the Unfolded wiki page to a local HTML file, download new images and rewrite/replace structural elements and details
• hyphens: hyphenology, see templates/template.html and js/runHyphens.js
• baseline grid: px calculation + manual shifts of images in css/print.css + csss/baseline.css
• footnotes: are structured by MediaWiki and are wrapped in HTML elements when the content is pulled using the MediaWiki API
• pre-press: see the folder tools for different scripts to convert PDF color space, PDF format, PDF resizing, and more

Software dependencies

• jinja2==3.1.2
• markupsafe==2.0.1
• pdftk (adding Multi)
• pdfunite (adding Multi)
• resample (PDF resizing)
• xelatex (PDF formatting)

OSP-tools.pdfutils: rgb2cmyk-overprint.sh

Convert PDF from RGB to CMYK, with overprint enabled on the whole document

Dependencies:

• gs (Ghostscript)
• pdftops
• control.txt
• apple_to_jNP_photo.icc
• apple_to_jNP_neutral.icc

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

Usage:

./rgb2cmyk-overprint.sh input.pdf

Link: http://osp.kitchen/tools/pdfutils/

OSP-tools: resample.sh

Dependencies:

• gs (Ghostscript)

This will change the resolution of a PDF.

Usage:

./resample input.pdf 150

Custom VR tools: make-images-bw.sh

Dependencies:

• imagemagick

This will create a copy of an image folder, with all images converted to BW.

Usage:

./make-images-bw.sh ./images-folder/

Custom VR tools: convert-to-PDFX-3-2002.sh

Dependencies:

• texlive-xetex (xelatex)

This will convert a PDF into the PDFX/3:2002 format + edit the PDF metadata.

Edit PDF metadata:

Open the xelatex template (`xelatex-PDFX-3-2002.template.tex`) and edit the metadata on line 7-12.

Usage:

convert-to-PDFX-3-2002.sh input.pdf output.pdf

Custom VR tools: separatecolors.sh

Dependencies:

• gs (Ghostscript)

This will convert the PDF into a set of TIFF files, which is useful to inspect how the colors are spread over the different color "plates".

The script generates one TIFF for:

• full color
• cyan plate
• magenta plate
• yellow plate
• black plate

Usage:

./simulateoverprint.sh input.pdf

Other useful tools

• Check metadata of PDF: pdfinfo filename.pdf
• Check color space of PDF: pdfimages -list filename.pdf
• Check colors of PDF: identify -verbose filename.pdf
