The planisphere is edited on a mapping software in order to integrate the desired geographical information then cut into rectangular areas. The resulting files are then converted into almond-shaped gores to fit the sphere.
Each gore is then custimized using publishing software: All relevant information is added such as the coasts, the lakes and rivers the cities but also the personalizations.
All the gores are then printed on acid-free paper specially chosen for its preservation characteristics and its ability to deform when applied to the sphere. The black ink used is based on pigments, thus guaranteeing long life.
Then comes the coloring of the maps with watercolor: It is a crucial and very meticulous step in order to obtain a perfect rendering once the globe is made. Many layers are necessary to obtain nuance and depth of the globe. The watercolours used come only from the best suppliers, such as Sennelier Extra Fine, Old Holland or Winsor and Newton.
