Let's assume that I'm writing an A4 book.
How can I design front cover, spine, and back cover of the book with ConTeXt?
I've read many PDF files, but none that I can remember actually had book spine on it. Some had back cover. Most had front cover.
Do printing houses make spine and back cover for authors so that back cover and spine don't need to be typeset by LaTeX or ConTeXt?
No, they don’t, you must provide an extra PDF in the right size. Often, printshops provide a template. If I don’t have a design that goes over the spine, I use a cover.tex that imports front and back of my main PDF and just add the spine text. Everything placed on a layer. This way, my main PDF contains everything except the spine – makes sense for proofreading or digital distribution. Spine width depends mostly on page number and paper weight (thickness), but also on the binding technology used – ask your printshop. Hraban
