His approach relied on systematic cross-hatching to create tonal depth. In works like Mater Pietatis and Nun, Morghen used varying weights of line to suggest the softness of fabric. He reinterpreted paintings for a medium that relied on black ink and white paper rather than simply copying them. His portraits, such as that of Adeodato Turchi, show a focus on anatomical accuracy and steady hand control. This discipline was a hallmark of the Florentine school of engraving during the nineteenth century.

Modern collectors value Morghen for the graphic clarity his prints provide. His engravings offer a way to appreciate Old Master compositions through a monochromatic lens. The sharp lines and geometric precision suit contemporary interiors that favour clean aesthetics. These prints provide a connection to European art history without the heaviness of oil paint. His versions of the Madonna of Casa Tempi remain popular for their balanced proportions and technical execution.
