Embroidery Digitizing
Contents
Introduction
Embroidery digitizing is the process of creating a stitch file for an embroidery machine to sew. The stitch file can be in one of several formats. The embroidery machines at TinkerMill use PES and DST formats (less common).
The stitch file contains a list of commands telling the embroidery machine where to sew, when to trim the threads, when to switch colors, etc.
The process of creating a stitch file is done in digitizing software. We have SewART, PE-Design NEXT and Embrilliance. This Wiki will only cover digitizing with Embrilliance. If you are interested in using PE-Design NEXT or SewART, please see the Resources below for more information.
You can run SewART and/or PE-Design NEXT from the Textiles PC. Embrilliance is installed on at least the Textiles PC and the two laptops available for general use in the front office.

Embrilliance
Embrilliance is an embroidery software package with several modules which add different kinds of functionality. TinkerMill has purchased the following modules:
- Essentials
- Enthusiast
- Stitch Artist Levels 1-3
Essentials and Enthusiast add a lot of capabilities to do things like add words to a design, merge designs, edit colors, flip designs, etc. These are all the things you would want to do if you wanted to work with stitch files you may have purchased. Stitch Artist is the module which is used to create new designs. This is where we will focus our attention.
The MANUAL for the software can be downloaded from the Embrilliance website here or directly here. The manual contains information about all of the modules.
You can also download a demo version of Embrilliance to practice at home with. It works on both PCs and Macs so be sure to pick the right version.
Excellent tutorials abound on the internet for learning Embrilliance. I highly recommend subscribing to the following on YouTube:
PE-Design NEXT
We have PE-Design NEXT available to use on the Textiles PC. It requires the use of a dongle which should already be attached. PE-Design can also be used to create new designs. However, its interface is a little more cumbersome to use than Embrilliance so I (Lynne Newberry) feel that Embrilliance is the better product to use.
However, PE-Design does have some functionality that Embrilliance lacks. You can create designs based on photos. You are welcome to use this software at any time.
The MANUAL for the software can be downloaded here.
SewArt Embroidery Digitizer
We have SewArt installed on the Textiles PC. This is fairly inexpensive software for digitizing. The MANUAL can be downloaded here. You can download a demo from their website here.
InkStitch extension to Inkscape
If you're feeling adventurous, you can try adding the Ink/Stitch extension to Inkscape and use it to create designs.
Digitizing a Simple Design: Considerations
Let's imagine we have a simple image that we'd like to convert to an embroidery design. How do we approach this?
How big do we want our final design to be? Typical over-the-pocket logos are designed to fit within a 4" x 4" hoop. Back-of-a-shirt designs can be much larger, but could become quite dense and stiff. They also take much longer to sew.
How much detail do we want to preserve in the stitched design? It can become impossible to preserve tiny details in a design. Sometimes a simplification of the design is needed to better convey the logo.
How many thread trims will there be? Thread trimming causes the machine to slow down. If you will be doing production embroidery, then the faster the design stitches the better. You can reduce the overall stitching time by reducing the number of thread trims and color changes. Sometimes you can add a line of running stitches between one block of stitching and another of the same color in order to eliminate a thread trim. These "travel" stitches should be in an area which will be stitched over later on.
How many thread colors will there be? On a machine with 6 needles, it is more efficient to keep your total number of colors to 6 or fewer. If you are looking for two shades of a similar color, you can stitch areas using different stitch directions or fill patterns to create different looks with the same color.
Do you have a version of the design in vector format? This can simplify the digitizing process greatly. You can use Adobe Illustrator or Inkscape to create .ai or .svg files. Embrilliance will usually read both formats. However, the simpler the file the greater the chance of success. Keep in mind that if you have two overlapping closed shapes, these can be converted to two overlapping areas of stitching. If you want the two areas to abut, then the closed vector shapes should also abut.
If you do not have vectors for your design, you can create them in Embrilliance, Inkscape, or Adobe Illustrator. In Embrilliance, you use the Magic Wand tools. In Inkscape, you can use the ... In Adobe Illustrator, you use the Image Trace tool. In all cases, you will end up with vectors with too many nodes. You get the best shapes when using a minimum number of nodes. So it is recommended that you clean up your vectors before converting them to stitches.
Basic Concepts
You could create an embroidery design by choosing the location of each stitch by hand. I believe this is called manual punching. But usually it is easier to start with lines and closed polygons, converting those shapes into lines of stitching or areas to be filled with stitching.
For example a line could be sewn with a running stitch, a zig-zag stitch, or stitched with a motif.
EXAMPLE
A closed polygon can be filled with a dense satin stitch or a fancy fill pattern.
EXAMPLE
There is one more shape that is commonly used: a variable width column, which is much like a zig-zag on a line, but has variable width.
EXAMPLE
These are the basic building blocks of digitizing. Aside from manual punching, every design you create will start with lines, polygons, and sometimes variable width columns. Even text can be broken down into lines, polygons, or variable width columns. But usually your digitizing software will make adding text seamless.
How do we get our Lines and Polygons?
There are usually several ways to create lines and polygons:
- draw by hand in the software
- use built-in shapes in the software (such as circles or stars)
- import vector files (from, say, Inkscape)
- use built-in tools to auto-digitize a very clean image
Not all digitizing software will have an auto-digitizing option. If it does not, you can use Inkscape to create vectors from clean images using the XXX option. It is suggested that you clean up the vectors first before importing them into your digitizing software.
