Whether wireframe or expanded, scaling a design too far can lead to thread breaks.
Shrinking Designs
Scaling a design down can produce thread breaks by creating stitches smaller than the diameter of the needle. When wireframe designs are scaled down, all the input points are moved closer together. Since each input point results in a needle penetration, this can create stitches that are too small.
How Much is Too Much?
How far you can scale a design depends on the type of file as well as the amount of detail in the design. If the design is relatively simple, your chances of scaling success are better than a design with a good deal of small detail.
As a general rule,
- Expanded designs should be scaled only around 10-15% from their original size.
- Wireframe designs should be scaled only around 25-30% from their original size.
Some designs may be scaled beyond these limits, but the success of the sewout will depend on how the design was originally digitized. Embroidery designs are rarely capable of being scaled to fit all needs.
