His technique focused on tonal depth and the weight of shadows. Lauwers avoided the stiff lines common in earlier woodcuts. Instead, he used swelling lines to suggest the volume of human forms and the texture of heavy drapery. He often worked from designs by Gerard Seghers and Anthony van Dyck. His prints maintain the drama of the original Baroque paintings while functioning as independent works of graphic art. The clarity of his compositions makes the religious scenes easy to read.

Modern collectors value Lauwers for his ability to bring Baroque scale into a domestic setting. His monochrome prints offer an alternative to large oil paintings. They fit well in interiors that use a neutral palette. These engravings provide a direct link to the Golden Age of Flemish art. The sharp contrast of black ink on paper creates a graphic quality that remains modern.
