His technique relied on a controlled use of line and burin work. In pieces like Salvator Mundi, Dalcò focused on clear tonal transitions rather than heavy hatching. This method preserved the softness of the original paintings. His portrait of Michele Colombo shows his ability to capture character through subtle variations in texture. He avoided the dramatic contrasts common in earlier centuries. He preferred a balanced neoclassical clarity.

Dalcò later became a professor at the Academy of Fine Arts in Parma. Modern collectors value his work for its technical precision. His prints offer a way to own a refined interpretation of classical religious subjects. The monochromatic nature of his engravings suits contemporary interiors that favour neutral palettes. These works provide a sense of historical continuity. They function as quiet additions to a curated wall. They offer a window into the rigorous standards of nineteenth-century Italian printmaking.
