Play around with your CFG settings, monochrome images usually handles a higher CFG than usual. A higher CFG gives more contrast and a lower CFG will make it softer.

LoRA Strength Guide
Strength 0.5 = Less style, more tidy and clean, better coherence
Strength 0.80 = More style, mid coherent images
Strength 1.0 = Very stylized, more abstract, more impressionistic

Other settings:

Checkpoint: PixelWave 09
Sampler: DPM++ 2m / DPM++ SDE
Scheduler: Align Your Steps (AYS)
CFG: 2.5

Notice:
Trained on around 40 high-res prints at 1536px max.res.
Most of the training images are from early 20th century scandinavia (Anders Zorn), so you might run in to some specific bias from that time-era/location.

Trigger words

You should use Etching, dark background, bright and plain background, pencil sketch, oil painting to trigger the image generation.

Download model

Weights for this model are available in Safetensors format.

Download them in the Files & versions tab.

Use it with the 🧨 diffusers library

from diffusers import AutoPipelineForText2Image
import torch

device = "cuda" if torch.cuda.is_available() else "cpu"

pipeline = AutoPipelineForText2Image.from_pretrained('stabilityai/stable-diffusion-xl-base-1.0', torch_dtype=torch.float16).to(device)
pipeline.load_lora_weights('WizWhite/wizard-s-vintage-etchings', weight_name='Wizards_Etchings-000008.safetensors')
image = pipeline('`Etching`, `dark background`, `bright and plain background`, `pencil sketch`, `oil painting`').images[0]
