Creating vibrant multicolor artwork with the UUNA TEK 3.0 Pen Plotter is easier than ever. Whether you're producing artistic illustrations, branding graphics, or automated pen-written projects, this step-by-step guide will show you how to separate colors in Inkscape, prepare layers correctly, and plot each color with precision. Follow the instructions below to achieve clean, professional multicolor plotting results.
1. Prepare a Colorful SVG File and Open It in Inkscape
Start by selecting or designing a multicolor SVG illustration. Open the file using Inkscape, which offers precise vector editing and full compatibility with UUNA TEK plotter extensions.

2. Create Color-Separated Layers in Inkscape
Since the UUNA TEK 3.0 pen plotter draws one pen color at a time, all strokes of the same color must be placed in the same layer.
Create five new layers: Red, Blue, Green, Purple, Black
Go to Layer > Layers and Objects
Add new layers as needed

Important: Layer names must start with a number for proper G-code processing.

This ensures clean organization and smooth plotting transitions when switching pens.
3. Move Same-Color Strokes Into Their Corresponding Layers
Select all strokes of the same color in your SVG.
You can hold Shift to select multiple elements

After selecting, right-click → Move to Layer

Place each color group into its matching layer (red strokes into the red layer, etc.)

After completing the sorting, every stroke will be neatly organized into the correct color layer.

4. Start Plotting the Red Layer First
Begin your multicolor drawing by plotting the red layer:
Turn off visibility for all layers except the red layer

Insert your red pen into the pen holder
Go to Extensions > UUNA TEK 3.0 PLOTTER

Choose your cache directory
Click Apply

Select the correct COM port
Add the COM port to the right panel
After the G-code path is generated, click Print

The UUNA TEK 3.0 pen plotter will now draw the red portion of your design with precision.

5. Repeat for Blue, Green, Purple, Black… One Color at a Time
For each color:
Insert the corresponding pen
Hide all other layers
Leave only that color layer visible

Generate G-code
Click Print
Repeat until all colors have been plotted.
This ensures perfect color alignment without smudging or overlap.
6. View Your Final Multicolor Artwork
After completing all layers, your UUNA TEK 3.0 Pen Plotter will produce a beautifully layered, vibrant multicolor drawing. Each part of the illustration aligns precisely thanks to the layer-based workflow and UUNA TEK’s accurate plotting mechanism.
Conclusion
With properly organized layers and simple color-by-color plotting, the UUNA TEK 3.0 Pen Plotter becomes a powerful tool for producing professional multicolor illustrations. Whether you're creating artwork, branding assets, or personalized stationery, this workflow ensures clean lines, accurate color separations, and stunning final results. Master these steps once, and you'll be able to create endless multicolor designs with confidence.
