#3909 Black Tape Outlines on Glass with White Background
#3909 Describe how to use Nano Banana Pro to produce a "black tape outline" of an image to be inserted between two panes of glass with a white background. Thinking vinyl cutter.
It sounds like you want to transform that sketchy eagle drawing into a clean, bold design that mimics the look of lead came (stained glass) or industrial black tape, ready for a vinyl cutter.
Since Nano Banana Pro (the current Gemini 3-based image model) excels at semantic understanding and cleanup, you can use it to skip hours of manual node-editing in vector software.
Here is the workflow to get that "black tape" look using Nano Banana Pro and your vinyl cutter.
Phase 1: The "Nano Banana Pro" Process (Cleanup & Style)
Your current image has sketchy, disconnected lines. A vinyl cutter will try to cut every single scratch and jitter, which will ruin the vinyl. You need Nano Banana Pro to "hallucinate" a cleaner version.
Upload the Eagle Image to the Nano Banana Pro interface.
Use a "Stencil/Vector" Prompt. You want to force the AI to ignore the pencil texture and output solid geometry.
Draft Prompt: "Redraw this eagle as a high-contrast, black-and-white vector stencil. Use thick, uniform-width solid black lines (like electrical tape art). Close all major shapes. Remove all sketchiness, shading, and noise. Pure white background."
Refine for "Cut-ability":
If the lines are too thin, add: "Make lines bolder."
If the lines are disconnected (which makes peeling vinyl a nightmare), add: "Ensure all lines are connected where possible for a single-piece decal."
Phase 2: The Vector Bridge (Raster to Path)
Nano Banana Pro generates a raster image (pixels), but your cutter needs paths (vectors).
Download the result from Nano Banana Pro (highest resolution available).
Import to your Cutter Software (Cricut Design Space, Silhouette Studio, or Inkscape).
Trace the Image:
Look for the "Trace Bitmap" or "Image Trace" function.
Since Nano Banana Pro gave you a high-contrast B&W image, you can crank the "Threshold" up.
Crucial Step: Ensure you are tracing the Outline, not the Centerline. You want the software to create a cut path on both sides of the black line (creating a "lane" for the black vinyl).
Phase 3: The "Black Tape" Cut & Assembly
This is where the physical "tape" effect happens.
The Cut:
Load Matte Black Vinyl (Matte looks more like electrical tape/lead than Gloss).
The cutter will cut the edges of your thickened lines.
The Weed (The Inverse):
This is the brain-twister. You are not keeping the eagle shape; you are keeping the lines.
Weed away the white parts (the inside of the wings, the head, and the background).
You should be left with a skeleton of black vinyl on the carrier sheet.
The Sandwich (Glass Assembly):
Clean your first pane of glass thoroughly (alcohol wipe).
Apply Transfer Tape to your black vinyl skeleton.
Transfer the vinyl to the First Pane of Glass.
Place the Second Pane of Glass directly on top of the vinyl. This "encapsulates" the sticker, protecting the sharp edges and giving it depth.
Place your White Background behind the rear pane (or paint the back of the rear pane white for a permanent shadow-box effect).
Pro Tip: If you want the eagle to "float," separate the layers. Put the black vinyl outline on the front pane, and put a solid white silhouette of the eagle on the back pane (or the white background). This creates a physical gap and a real shadow, enhancing the 3D effect.
