A center walk underlay is good for narrow columns, while a zigzag is beneficial for larger fill areas to prevent shifting. |
| 9. Pull Compensation | Managing Fabric Distortion | Pull compensation adjusts for the natural pull on the fabric caused by the embroidery, which can distort designs. Increasing pull compensation makes stitches slightly longer to counteract this. Too much compensation can make the design look loose or overly stretched, while too little can result in designs appearing too tight or puckered. |
| 10. Lock Stitches and Trimming | Securing Thread Ends | Lock stitches are small, unobtrusive stitches at the start and end of a thread path to prevent unraveling. Trimming settings manage automatic thread cuts between jump stitches. Incorrect settings can lead to loose threads or unnecessary trimming that extends the embroidery time and uses more thread. |
| 11. Tension Settings | Adjusting Thread Tension | Proper thread tension is crucial for smooth stitch formation. While specific tension adjustments are made on the machine, understanding how your design's density and material choice affect tension can help prevent issues like thread breakage or looping stitches. Dense designs on stretchy fabrics may require tighter machine tension. |
| 12. Design Optimization | Reviewing and Refining the Embroidery File | Optimizing the design involves reviewing stitch paths for efficiency, ensuring the design fits within the hoop size, and that stitch density is appropriate for the fabric type. Overly dense designs can cause needle breakage and fabric distortion, while too sparse can leave the fabric visible through the design. |
Understanding and adjusting these advanced parameters in the Bernina Designer Software can significantly enhance the quality of your embroidered logo. Optimization involves a balance between aesthetics and functionality, ensuring the final product is both beautiful and durable.
