How to Convert a Signature Image to SVG and Write It Automatically with the iAuto Writing Machine

Automating handwritten signatures can save a significant amount of time when handling bulk letters, envelopes, or documents. With the UUNA TEK iAuto automatic writing machine, you can transform a scanned signature into a realistic handwritten result using an SVG file.

This step-by-step tutorial shows how to convert a signature image into SVG format and use the iAuto handwriting machine to write signatures automatically.

Step 1: Open the Signature Image in Inkscape or Adobe Illustrator

First, prepare a signature image (usually scanned or photographed).

Open the image using vector design software such as Inkscape or Adobe Illustrator. These tools allow you to convert raster images into vector graphics, which are required for the iAuto writing system.

Step 2: Trace the Signature Using the Pen Tool

Select the Pen Tool and carefully trace the signature.

Instead of using automatic tracing, manually connect points along the signature lines. This method creates a much more natural and realistic handwriting effect, which is especially important when using an automatic signature machine.

By placing anchor points along the strokes, you can accurately recreate the flow of the original handwriting.

Step 3: Delete the Original Image and Save the Signature as SVG

Once the tracing is complete:

1. Delete the original raster image.
2. Keep only the traced vector signature.
3. Save the file in SVG format.

SVG (Scalable Vector Graphics) is the required format for most automated handwriting devices, including the UUNA TEK iAuto writing machine.

Step 4: Measure the Signature Position on the Paper

Now it's time to prepare the signature placement.

For example, if you want the signature to appear in a specific location on a document, you need to measure:

• The distance from the left margin
• The distance from the top margin

In this example:

• Left margin distance: 9.4 cm
• Top margin distance: 13.8 cm

Accurate measurement ensures the automatic handwriting machine writes the signature in the correct position on every sheet.

Step 5: Import the SVG File into UUNA TEK Software

Open the UUNA TEK control software and import the SVG signature file.

After importing:

• Click the Origin Position.
• Select the SVG file.
• In the popup dialog, check the box first, then uncheck it again.

After doing this, the signature display will change to the correct format for writing.

Step 6: Set the Paper Size

Next, configure the paper size settings inside the software.

Make sure the dimensions match the actual paper you are using (for example A4, Letter, or custom size). Proper paper configuration ensures the iAuto writing machine positions the handwriting accurately.

Step 7: Create Reference Lines for Positioning

To precisely position the signature:

• Create two reference lines.
• Place them at 9.4 cm and 13.8 cm.

How to create reference lines:

• Click the top ruler and drag downward to create a horizontal reference line.
• Click the left ruler and drag to the right to create a vertical reference line.

These reference guides help align the signature perfectly.

Step 8: Position the Signature and Generate G-Code

The intersection of the two reference lines marks the exact location where the signature should appear.

Next:

• Resize the signature to the appropriate size.
• Move it to the intersection point.
• Click Current to generate the G-code.
• Insert the paper into the machine upside down.
• Click Write to start the automated handwriting process.

The iAuto handwriting robot will now reproduce the signature on the document.

Step 9: Final Signature Result

After the writing process is complete, the document will display a realistic handwritten signature created by the iAuto writing machine.

This method allows you to produce consistent, natural-looking signatures for bulk letters, direct mail campaigns, certificates, or personalized documents.

Summary

By following these steps, you can easily convert a signature into an SVG file and use the UUNA TEK iAuto automatic writing machine to produce realistic handwritten signatures at scale.

This workflow is ideal for:

• Bulk mail campaigns
• Personalized letters
• Envelope addressing
• Automated document signing
• Handwritten marketing materials

With the right setup, an automatic handwriting robot can replicate natural handwriting while saving hours of manual work.
