Understanding compensation
When an embroidery design stitches, the fabric and stitches don't remain perfectly still. The tension created as stitches are formed can cause areas of the design to pull inwards or spread out slightly.
Compensation is the allowance built into an embroidery design to account for this movement.
You may also hear this referred to as push and pull compensation.
You don't need to digitize your own designs to understand compensation. Knowing what it does can help you recognise why gaps, outlines or misaligned areas sometimes appear in finished embroidery.
What Is Push and Pull?
As stitches are formed, they can distort the shape of an embroidered area slightly.
Generally:
- Pull can cause an area to become narrower in the direction the stitches are travelling.
- Push can cause the embroidery to spread slightly at the ends of the stitches.
The amount of movement varies depending on the design, fabric, stabilizer, thread, tension and other embroidery conditions.
A digitizer takes this movement into account when creating the design.
For example, an embroidered shape may intentionally be made slightly wider than the finished shape requires. Once embroidered, the stitches pull inwards and the shape appears closer to the intended size.
Why Designs Don't Always Line Up Perfectly On Screen
If you look closely at a well-digitized embroidery design in software, you may notice that some objects overlap or extend slightly beyond where you expect them to.
This isn't necessarily a mistake.
The digitizer may have deliberately added overlap or changed the shape of an object to compensate for movement during embroidery.
For example, two coloured areas that are supposed to meet may overlap slightly in the design file. As the embroidery stitches and the fabric moves, this overlap helps prevent a gap appearing between them.
What looks perfect on screen isn't always what produces the best embroidery.
What Happens When There Isn't Enough Compensation?
Insufficient compensation can result in registration problems, where parts of the finished embroidery don't align correctly.
You might notice:
- gaps between adjoining colours
- fabric showing between embroidered areas
- outlines that don't follow the edge of the design
- lettering that appears uneven
- shapes that look narrower or distorted after stitching
These problems can sometimes be caused by the embroidery setup rather than the design itself, so it's important to consider both.
Can There Be Too Much Compensation?
Yes.
Too much compensation or unnecessary overlap can create areas with excessive stitching, making the embroidery thick or bulky.
As with density, the goal isn't simply to add more stitches. Good digitizing uses enough compensation to account for the expected movement without creating unnecessary bulk.
Fabric and Stabilizer Make a Difference
The amount of movement during embroidery isn't the same on every project.
A stable woven fabric generally behaves differently from stretchy knit fabric, towels or other unstable materials. The way the project is stabilized and hooped can also affect how much movement occurs.
This means the same embroidery design can sometimes produce slightly different results on different fabrics.
Correct stabilizer, hooping and embroidery technique help minimise unwanted movement and allow the compensation built into the design to work as intended.
Underlay built into the embroidery design can also help support the fabric and control movement as the design stitches. Learn more in our Understanding Underlay in Machine Embroidery Designs guide.
Is It the Design or Your Embroidery Setup?
If you're experiencing gaps, outlines that don't line up or other registration problems, it doesn't necessarily mean the design has been poorly digitized. Movement during embroidery can also affect the finished result.
Before blaming the design, check that:
- you're using a suitable stabilizer
- the fabric is securely hooped or supported
- the project hasn't moved during embroidery
- your machine tension isn't excessively tight
- the needle and thread are suitable for the project
- the design hasn't been significantly resized
If possible, test the design again on a stable woven fabric with appropriate stabilizer. If the same registration problems repeatedly appear in exactly the same areas, the problem may be within the design itself.
For more detailed troubleshooting, including why outlines may not line up correctly, see our Design Registration and Design Outlines guide.
Can Compensation Be Adjusted in Software?
If you're using a purchased or ready-made embroidery design, compensation has usually already been determined by the digitizer.
Some embroidery and digitizing software allows pull compensation to be adjusted, while more advanced digitizing software allows individual objects to be reshaped, overlapped or otherwise adjusted to account for movement.
However, compensation isn't simply a setting that should be increased whenever you see a gap. The cause of the movement needs to be understood first.
Understanding the Finished Result
Machine embroidery involves thread, fabric and stabilizer interacting while thousands of stitches are being formed. A small amount of movement is normal.
Good compensation anticipates that movement so the finished embroidery looks correct, even if the design itself doesn't look perfectly aligned when viewed closely on screen.
As an embroiderer, the most important thing is being able to recognise the difference between a problem caused by your embroidery setup and one that may be built into the design.
