His technique involved a precise system of lines that managed to imitate the textures of oil paint. In works like his portrait of René Descartes or the Holy Family at Table, he translated the soft gradients of skin and the heavy folds of silk into a monochrome language. He collaborated with Charles Le Brun to document the faces of the French Enlightenment and the aristocracy. His prints are defined by a clarity that avoids the blurred edges common in other reproduction methods of the period.

Modern collectors value Edelinck for the architectural quality of his compositions. These engravings provide a sharp, graphic look that fits well in minimalist or classical interiors. The portraits, such as those of Henricus Goltzius or Queen Ulrika Eleonora, offer a window into the formal aesthetics of the Baroque era. His work is a study in how simple black lines on paper can create a sense of three-dimensional form and physical presence.
