Celebrate Father's Day in a creative and meaningful way by designing a personalized card using three different machines, all controlled from a single computer. This guide walks you through each step of the process—from preparing your design to printing and writing the final message—using UUNA TEK machines and software tools.
Card Design Overview
The Father's Day card consists of three key elements:
Envelope: Featuring “Happy Father’s Day” written on the front.
Letter Paper (Upper Half): A unique illustration in the top-right corner.
Letter Paper (Lower Half): A personalized message to your father.
Required Equipment and Software
Hardware:
Software:
- DrawingBotV3 (image-to-vector conversion)
- Inkscape (vector editing)
- UUNA TEK for iAuto
- UUNA TEK for U3
Step-by-Step Instructions
Step 1: Select a Photo
Choose a meaningful image you would like to include in your card design.

Step 2: Convert the Image to SVG
Use DrawingBotV3 to convert the photo into an SVG (Scalable Vector Graphics) file suitable for vector plotting.

Step 3: Edit the SVG in Inkscape
Open the SVG in Inkscape.
Trim any unnecessary elements from the image.
The goal is to isolate and clean up the artwork for printing.


Step 4: Adjust Document Size
Set the document dimensions to match the actual greeting card size:
Width: 115 mm
Height: 170 mm

Step 5: Position the Artwork
Resize and move the image so it appears in the top-right corner of the document layout.

Step 6: Print the Artwork Using iDraw HS-A3
Use the iDraw HS-A3 extension in Inkscape:
Go to Extensions > iDraw HSE Control
Send the design to your machine for drawing.

Step 7: Add Text Using UUNA TEK for iAuto
Launch UUNA TEK for iAuto.
Import a background image matching your greeting card size (11.5 cm × 17 cm).
This background helps accurately position your text.
📷 Tip: When photographing your card background, keep the image level and crop out unnecessary areas to ensure precise alignment.

Step 8: Prepare Background in UUNA TEK for iAuto

Open the trimmed background photo.

Load the previously edited SVG image.

Add two text boxes:
One for the recipient’s name
One for the personalized message

Step 9: Enable Personalized Messages

To write unique messages for different people:
Create a table (e.g., in Excel or CSV format):
Column A: Names
Column B: Messages
In UUNA TEK for iAuto, bind:

The upper text box to Column A
The lower text box to Column B


The software will generate 10 personalized greeting cards using this data.

Step 10: Save Template and Generate G-Code

Save the project as a reusable template.
Generate G-code files for the writing sequence.
⚠️ Note: Do not start writing at this stage—we are only preparing the template.
Creating the Envelope Template
This process is simpler, as you only need to add a general greeting to a predefined envelope size.
Define paper size: 120 mm × 90 mm
Choose any location on the envelope to write “Happy Father’s Day.”

Use UUNA TEK for U3 to:
Import background and SVG graphics (if needed)

Generate the image-writing layout

Final Production
Once all templates are ready, connect your devices and insert pens and paper into each machine. Proceed with the coordinated drawing and writing process.

Machine Assignments:
iDraw HS-A3 and U3-A3: Responsible for illustrations

iAuto: Responsible for writing personalized messages

Results
After the drawing and writing processes are complete, you will have a set of professionally crafted, fully customized Father’s Day cards and envelopes.
