Morghen followed the Neoclassical tradition, which prioritised clear lines and formal balance. He developed a specific system of cross-hatching to represent different textures and light levels without using colour. In his Portrait of Michelangelo Buonarroti, he used varying line weights to define the features of the face and the folds of the clothing. This method required extreme physical control and a deep understanding of how the human eye perceives depth on a flat surface.

Modern collectors often choose Morghen prints for their architectural clarity and historical accuracy. The black and white compositions provide a sophisticated look that pairs well with contemporary decor. These works represent the peak of reproductive engraving before the invention of photography. They offer a way to display the compositions of the Old Masters through the lens of eighteenth-century technical skill.
