Book creation using almost entirely open source tools

Some years ago I wrote a book. Now I have written a second one, but because no publisher wanted to publish it I chose to self-publish a small print run and hand it out to friends (and whoever actually wants one) as a a very-much-not-for-profit art project.

This meant that I had to create every PDF used in the printing myself. I received the shipment from the printing house yesterday.  The end result turned out very nice indeed.

The red parts in this dust jacket are not ink but instead are done with foil stamping (it has a metallic reflective surface). This was done with Scribus. The cover image was painted by hand using watercolor paints. The illustrator used a proprietary image processing app to create the final TIFF version used here. She has since told me that she wants to eventually shift to an open source app due to ongoing actions of the company making the proprietary app.

The cover itself is cloth with a debossed emblem. The figure was drawn in Inkscape and then copypasted to Scribus.

Evert fantasy book needs to have a map. This has two and they are printed in the end papers. The original picture was drawn with a nib pen and black ink and processed with Gimp. The printed version is brownish to give it that "old timey" look. Despite its apparent simplicity this PDF was the most problematic. The image itself is monochrome and printed with a Pantone spot ink. Trying to print this with CMYK inks would just not have worked. Because the PDF drawing model for spot inks in images behaves, let's say, in an unexpected way, I had to write a custom script to create the PDF with CapyPDF. As far as I know no other open source tool can do this correctly, not even Scribus. The relevant bug can be found here. It was somewhat nerve wrecking to send this out to the print shop with zero practical experience and a theoretical basis of "according to my interpretation of the PDF spec, this should be correct". As this is the first ever commercial print job using CapyPDF, it's quite fortunate that it succeeded pretty much perfectly.

The inner pages were created with the same Chapterizer tool as the previous book. It uses Pango and Cairo to generate PDFs. Illustrations in the text were drawn with Krita. As Cairo only produces RGB PDFs, as the last step it had to be converted to grayscale using Ghostscript.
