Not really, we see ourselves more as a bridge between self-publishing and publishing in the true sense. We do not provide editorial work but can put you in touch with potential partners. We also work with publishers who might be interested in your book. As with us, you keep all your rights, you can freely and whenever you want to go under the wing of a publisher. By using the online sales platform / bookstore, you still benefit from the visibility of a publisher, with the difference that your profit margins are much higher. .

Basically, if you don't print a book, it doesn't cost you anything, but that's not the point. We print on demand and depending on the print run, the production price per copy varies. By requesting a quote here, you will get a very accurate idea of the production cost. ici, vous recevrez une idée très précise du coût de production.

For a book bought in a bookshop via a publisher, the author earns between 6 and 10% of the book's selling price. Imagine that a book bought for €20 in a bookshop earns the author about €1.6. By working with Indigo Projects, a book bought from the online shop at €20 will earn you the difference between the selling price and the production price. As an author you will earn much more than through the traditional channel.

Our organisation is 100% Belgian and family-run. We sometimes call on outside partners for certain finishing jobs or when necessary.

Technical Glossary 
  • Grammage :  A paper is often described by its grammage expressed in grams per m2.
  • Uncoated white offset paper: these papers are fairly white and give good colour rendition. They are typically used in educational, technical and management books that require text and images and in which the reader can easily make annotations. You could say that it is like a good quality copier paper. .
  • Bulky paper: these papers are typically used for novels. Their off-white/cream colour makes for a more pleasant, longer reading experience. They are called "bulky" because they are thicker than other papers of equivalent weight. This gives volume to your book. The higher the "hand", the thicker the paper. Bulky paper also has a more natural feel.
  • Semi-matt coated paper: These papers are more commonly known as "glossy" papers because the surface layer gives them a glossier appearance, as in magazines. They are suitable for prints where photos and colour are predominant. Think for example of comics, tourist guides,... Their disadvantage is that they are thinner, so the book will be thinner.
  • One-sided coated cardboard: this cardboard has two completely different sides: the coated side, as with coated paper, is the side printed often in colour for the cover. The spine is usually left blank. Most books are printed with such a cover.
  • Two-sided coated board: this board is used when the author wants the covers to be printed on the inside as well (2nd and 3rd cover)
  • Uncoated textured board: this type of board is often used for books that want to give a more artistic, luxurious image: the surface of the paper has a grain similar to that found in drawing paper
  • Hard cover: a 2mm thick cardboard covered with a printed paper gives rigidity to the cover. The book has a more prestigious image, but is also much more expensive to produce.
  • Laminating: This is a lamination of the cover to protect it further. Laminating is included in the price, either in a matt or glossy version
  • Anti-scratch lamination: this is a reinforced matt or glossy version so that any scratches are not visible
  • Soft-touch" lamination: some people compare its special touch to a "peach skin" touch.
