His technique is defined by a precise use of the burin to create depth. Flipart did not merely copy paintings. He adapted the tonal values of oil on canvas to the medium of black-and-white ink. In works like Storm in the Moonlight and Storm and Shipwreck by Day, he used fine lines to represent the movement of water and light. His ability to render the contrast between dark clouds and moonlight shows a technical mastery of the engraving process. He captured emotional weight without the use of colour.

Modern collectors value Flipart for the dramatic composition and clarity of his engravings. His maritime scenes provide a sense of movement that complements contemporary interiors. Historical portraits, such as those of Jacques Dumont and Jean-Baptiste Greuze, offer a window into the Enlightenment era. Because these works were originally intended for domestic display, they translate well to modern wall art. They offer a sophisticated aesthetic that relies on line and shadow.
