Sticker Studio ​

Sticker Studio provides an automated workflow to convert reference images and ideas into die-cut vinyl stickers. The studio runs entirely on your local machine through Stable Diffusion WebUI Forge or ComfyUI.

Every generated sticker includes a clean, die-cut border and an alpha-transparent background ready for production or digital sharing.

Key Capabilities ​

  • Local Engine Inference: Generate artwork through local Stable Diffusion Forge or ComfyUI instances.
  • Curated Style Presets: Select from six specialized sticker art styles with pre-tuned prompt keywords.
  • Auto-Cutout Isolation: Automatically detect and remove image backgrounds to isolate the primary subject.
  • Die-Cut Contour Tuner: Adjust white contour border thickness from 0 px to 24 px in real time.
  • Transparent Alpha Canvas: Inspect generated assets over an alternating high-contrast checkerboard grid.
  • One-Click Export: Copy 32-bit transparent PNGs to your system clipboard or save files to disk.

Interface Layout: Dual-Stage Workspace ​

Sticker Studio Dual-Stage Workspace

Sticker Studio uses a dynamic dual-stage canvas layout designed for creative focus:

1. Left Column: Input Deck (380 px) ​

The scrollable Input Deck contains all input controls:

  • Reference Image Drop Zone: Drag and drop PNG, JPG, or WebP reference images up to 25 MB.
  • Style Preset Chips: Select from six curated art styles to inject prompt keywords instantly.
  • Prompt & Negative Prompt: Customize positive prompt descriptions and unwanted visual artifacts.
  • Contour Settings: Toggle automated background cutout and adjust border width between 0 px and 24 px.
  • Generate Sticker Button: Start local inference and watch the pipeline progress.

2. Right Column: Output Preview Canvas ​

The flexible output canvas displays your rendering results:

  • Alpha Checkerboard Grid: High-contrast dark tiles (#12161c and #1a202c) highlight edge transparency and white die-cut contours.
  • Generating Overlay: Displays indeterminate progress bars and stage status messages during generation.
  • Export Action Pills: Quick-action buttons to copy transparent PNGs to the clipboard or save files to disk.

Curated Style Presets ​

Sticker Studio provides six curated art styles. Each preset injects specialized positive and negative tokens into your generation request:

Preset NameIconDefault BorderInjected Positive TokensInjected Negative Tokens

TIP

You can append custom prompt terms while preserving preset tokens. The studio automatically combines your custom text with the selected preset tokens.

4-Stage Generation Pipeline ​

When you click Generate Sticker, the request executes across four automated stages:

  1. Stage 1: Diffusion Generation:
    • Routes the prompt and parameters to your local Stable Diffusion Forge or ComfyUI backend.
    • Renders the subject with high contrast against an isolated solid background.
  2. Stage 2: Subject Isolation:
    • Removes background pixels automatically when Auto-Cutout is active.
    • Produces a clean RGBA transparent mask of the primary subject.
  3. Stage 3: Contour Application:
    • Dilates the subject alpha mask by the chosen border radius ($0\text{ to }24\text{ px}$).
    • Applies a solid white die-cut contour band around the outer boundary.
  4. Stage 4: Ready:
    • Renders the completed 32-bit transparent PNG onto the alpha checkerboard canvas.
    • Activates the floating export action pills.

Step-by-Step Generation Procedure ​

Follow these steps to create a sticker:

Step 1: Verify Engine Status ​

  1. Check the Telemetry Ribbon in the titlebar.
  2. Confirm that Forge or ComfyUI shows an active green status dot.
  3. If the engine is offline, open the Engines view and start the service.

Step 2: Provide Input Reference or Prompt ​

  1. In the Input Deck, drag and drop an image into the Drop Zone, or click Browse Files.
  2. Alternatively, leave the drop zone empty and type a description into the Custom Prompt field.

Step 3: Select a Style Preset ​

  1. Click a style preset chip (for example, 🏷️ Die-Cut Vinyl or 🌈 Holographic).
  2. The studio loads the default border width and token settings for that style.

Step 4: Configure Contour Settings ​

  1. Verify that Auto-Cutout is checked.
  2. Adjust the Die-Cut Border Width slider between 0 and 24 px (default: 12 px).
    • Set 0 px for borderless transparent cutouts.
    • Set 8–14 px for standard die-cut stickers.
    • Set 16–24 px for bold graphic badges.

Step 5: Generate and Export ​

  1. Click ✨ Generate Sticker.
  2. Watch the progress tracker during diffusion and contour processing.
  3. When generation completes, inspect the result on the checkerboard canvas.
  4. Click 📋 Copy PNG to copy the 32-bit transparent image to your clipboard.
  5. Click 💾 Save File to save the sticker to your outputs/stickers/ folder.

NOTE

Clipboard export writes a native 32-bit ARGB/PNG bitmap. You can paste the sticker directly into Discord, Slack, Photoshop, or office documents.

Hardware Fit & VRAM Guidelines ​

Sticker generation uses standard diffusion models. Review these memory guidelines for optimal performance:

Checkpoint FamilyRecommended ResolutionMinimum VRAMRecommended Engine
SDXL Sticker Checkpoints1024 × 10248 GBStable Diffusion Forge
SD 1.5 Sticker Checkpoints512 × 5124 GBStable Diffusion Forge
FLUX.1-schnell1024 × 102412 GBComfyUI / Forge

IMPORTANT

The built-in VRAM Orchestrator automatically unloads inactive Ollama text models before sticker diffusion starts. This prevents out-of-memory errors on 8 GB and 12 GB GPUs.
