His artistic approach was defined by the strict discipline of copperplate engraving. Fritzsch utilised a systematic arrangement of lines to create depth and volume. He avoided the soft, painterly effects often found in mezzotints of the same period. His portraits are notable for their directness and lack of excessive ornamentation. This style prioritised the clarity of the subject, making his work highly effective for book illustrations and official records where accuracy was more important than artistic flair.

Modern collectors value the work of Fritzsch for its clean aesthetic and historical value. The monochromatic nature of his prints allows them to integrate easily into various interior design schemes. His architectural views and maps appeal to those who appreciate the intersection of art and science. These prints offer a sense of structure and historical continuity. They represent a period when the precision of the engraver was the primary way to share visual information across Europe.
