- Ai for Zund
In this tutorial you’ll learn how to prepare Adobe Illustrator files for multiple Fab Lab & Design Lab machines, including embroidery, laser cutting, UV printing, and PCB workflows.

This document assumes basic Ai knowledge and familiarity with Adobe workflow.
Ai for Embroidery
File type: .Ai (before exporting)
[Description on what is going to be covered in this step]
Start with a full color vector file.
Here is the File we will be referring to:
If you don’t have a color vector file see Adobe Illustrator Basics: Photos and multi-color traces

Organization
For the embroidery machine, file organization and order matters. The embroidery machine will perform layers starting from the BOTTOM UP

Fill and base colors should be on the bottom of the layers

Any outlines or details should be towards the on the top

Grouping
Like colors should we in the same layer- with the exemption of small details like white in the eyes.
Small details should be the last to be added [moved to the top layer]. That way they dont get lost.


Overlap
To ensure seamless blend on stitches and no fabric gaps, layers need to overlap with each other.
Here you can see that the bottom color extends well over what will be visible

Exaggerated example (but you get the idea)
Outline
Last tip. All details should be a shape with a fill. Strokes with a thick width will not translate.

To fix this go to Object- Path-Outline Stroke


Once your File is completed you can head to the Embroidery i² Design Software on the PC in the Fab Lab Textile Space.

Examples: Not Overlap & Not Outline

In this example I did not overlap the artwork fully, the border was very thin and strokes where not all outlined (hat, cheek and mouth).
You can see where the overlap did not happen there is a bit of fabric exposed.

Examples: Overlap & Outine

Now bringing back our first example. We have a large overlap, thicker border and outlined stroke (hat, cheek and mouth).

Ai for Laser Cutting
File type: .Ai or SVG
In this section we will prep Illustrator files for laser cutting by using color-coded strokes for engrave, cut, & score and convert artwork to grayscale for photo engraving.
Engrave, Cut, Score
We use color to help separate what settings we would like to apply to each part of our artwork. (We set these in the software)
- Black: Engrave
- Red: Cut
- Blue: Score

Grayscale Engraving
Laser Cutter is able to self adjust its power to match brightness of colors in an image. I works with between the range of white (255,255,255) to Black (0,0,0). If we attempt to engrave a full image in color, we may get disappointing results due to colors being to close on the color spectrum and not having enough contrast. With this we Convert to a greyscale.

- Start with Full color vector art
- Convert Color image into a Grayscale
- Edit - Edit Colors - Covert to Grayscale
- Get Laser Engraving!


Relief Engraving: Gradient
Info referenced from Trotec Relief Engraving. See article for more information
A relief engraving means a deep engraving with differing heights, which are created by gray shades in the graphic. The Trotec laser automatically regulates its performance using these grayscales and thus generates different heights in only one pass. Recommended Materials:
Let’s make our own
- Start with Grayscale artwork
- Select section to start on
- Click on gradient fill [center]



Linear Gradient
In the Gradient setting you can adjust the range of white vs black. To give us a lot of contrast I pull back the black by move the diamond to the right.


You can adjust the direction of the gradient by editing the angel of the gradient.


Radial Gradient

In the gradient setting select the center setting for circular gradient effect.

Freeform Gradient

The last type freeform allows you to customized your gradient further by placing color points in your artwork.

This technique is great for creating shadows.

File type: SVG

Marking/ Silkscreen
- Fill or Fill & Stroke
- No specific stroke width
- Same size as Outline
- Export as SVG

Ai for UV Printer (UV to Zund)
File type: PDF
To print on the UV printer you will need to save your image as a .PDF file.
Sizing
Open a new file and make a new artboard the size of the material you plan to print on.
Poster boards available is 22 x 28 inch.

Add Images & Save
UV works well with high resolution raster images or vector images.
If setting up a file to go from UV printer to Zund make sure image is on its own layer.
If not you can save your image as a Adobe PDF.
Head to File-Save as and set Format to Adobe PDF. Then hit Save PDF


UV to Zund
If you are looking to print on the UV printer and then cut out your prints on the Zund then we will need to add registration marks to our work.
- On a separate layer from your image create 1/4 inch dots (.25).
- Add at least 3 dots to your file
- Lock registation marks


Save .Ai File & Save a PDF File
Once finished you can save this file as am .Ai File. This file will be used again to create the cut file for the Zund.
Save this File with the registration marks as a PDF as seen above.
Ai for Zund
File type: Ai and SVG
Zund needs a vector file or a path for cutting operations.
- If going from UV printer
- make sure to open saved.Ai file with registration marks.
- Hide UV image layer
- Make visible registration mark layer (keep locked)
- Make a new layer separate from locked registrations.
- Create or image trace a shape in new layer.
- Remove Fill and set stroke to black.
- Save image as and .Ai file or .SVG
