His approach relied on a precise control of line and shadow. In works like Escapees deposited in the forests of Cayenne, he used cross-hatching to create depth. His style often leaned towards the dramatic or the satirical. Drunken Philosophers shows his ability to capture human expression and irony. He maintained a sense of texture within the constraints of the woodblock medium. This technical skill ensured that every print retained the clarity of the original drawing.

Modern collectors value Gauchard for his historical perspective and graphic clarity. His prints offer a window into 19th-century French social attitudes. The stark black and white compositions suit contemporary interiors. Pieces like Incantation or The Jealous Wife provide narrative interest. These works function as both historical records and visual statements. They offer a sophisticated alternative to more common 19th-century lithographs.
