Embroidery Digitizing - How to Digitize a Logo - Part 2

Digitizing (Vectorizing) Image Areas

Fills and Outlines

Once the background artwork is prepared, the actual digitizing process can begin.

We will use Fill objects to digitize the solid colored areas, such as letters and graphical elements. Subsequently, we will layer thin black Outline Objects on top of these areas.

Fill objects are composed of long parallel stitches (when using the standard "plain fill" setting). These stitches are automatically divided into shorter segments to maintain proper thread tension and prevent loose loops. These divisions also provide the plain fill with a subtle visual texture. Due to these split stitches and their consistent stitching angle, fill objects are ideal for digitizing larger design elements.

Note: When using fill objects for lettering, the characters should be at least 1 cm (1/2 inch) high to ensure high-quality stitch results. They are not suitable for very small lettering or narrow satin-style objects.

Trims and Connections

A high-quality embroidery design should minimize jump stitches to accelerate the sewing process and ensure a cleaner finish. If a design contains no trims or color changes, it can be sewn continuously. While some trims are unavoidable, a digitizer should aim to reduce their frequency throughout the design.

To minimize trims, it is essential to strategically place the start and end points of each digitized area. If objects are positioned close to one another, their start and end points should be aligned so they can be linked using Connection objects. This creates a "nearest point connection", keeping the linking thread as short as possible.

Note: Closest point connections are not always mandatory. If a gap between connected objects will be covered by a subsequent object of a different color, the connection path should be hidden underneath that object, even if it is not the shortest physical path.

Starting the Digitizing Process

Object Inspector

All completed objects are listed in the Object Inspector.

Note that the character 'E' was created using the plain fill tool. If your design requires satin stitch lettering, please refer to the Manual Digitizing of Lettering tutorial.

Digitize the remaining letters using the same technique. For the letter 'm', place the start point on the left side and the fill end point on the right side. To achieve this, trace the nodes around the letter starting and ending on the left, then select the rightmost node, right-click, and choose the Place Last Stitch Here command. This setup allows for seamless connecting stitches between letters later in the process.

Creating Openings (Holes) in Objects

Letters like 'b' and 'd' require a different approach because they contain internal openings. First, create the outer contour with the fill tool, then define the hole using the Opening tool. Note that openings do not appear in the primary Object Inspector; instead, they are listed in the Parts Inspector, which manages the sub-components of complex objects.

Cloning Objects

Digitize the blue section of one nut using the fill tool. We will generate the remaining objects through duplication and rotation. Select the object and navigate to Main Menu > Transform > Transform Objects.

Set the rotation angle to 120 degrees and the Count to 3. Position the rotation center (indicated by a small circular icon) in the work area as needed. A semi-transparent preview of the new copies will appear. To finalize, click the Generate Stitches (bucket icon) button on the top bar.

Changing Object Colors

All blue parts of the image have been digitized and filled with red thread for visibility against the background. We will now change these to the correct blue color. Select the objects using any of the following methods:

Click and hold the primary mouse button on a blue color cell in the palette, drag the cursor to the selected items in the Work Area, and release the button to apply the color.

Adjusting Object Parameters

We need to change the stitch angle for the brown objects. If adjacent fill objects share the same stitch angle, the stitches may interleave, resulting in a jagged edge.

Select the three brown objects, right-click the selection, and choose the Parameters command. In the Parameters window, change the fill angle to 90 degrees and click OK.

Implementing Connections

The software generates connection stitches between the objects. In the image below, these are marked by small red arrows. If you see long stitches crossing through the center of objects, it indicates that the start and end points of your fills were not positioned correctly. While Studio creates straight connections by default, you can manually edit their shape by adding new nodes.
