This model has been trained on vintage drypoint proof plates - images engraved onto zinc using a metal or diamond stylus. The organic metal surface of the oxidised zinc complements the dark lines and burred edges of the engraved image.

Two versions of this model are available: one trained against the base SD1.5 model, and one trained against a specialised cartoon-style checkpoint. The former will work well with base SD1.5 and photorealistic checkpoints, the latter will work better for Western animation and anime style checkpoints.
