If your sewing machine has an embroidery function (Brother Innov-is NS80E, Janome Memory Craft 400E or Singer Quantum Stylist 9960) refuses to correctly read the loaded design; the problem in 80% of cases lies not in the technology, but in improper preparation of the file. Even a simple picture in the format .JPG from the Internet requires conversion to .PES/.DST, correction of stitch density and breakdown into color blocks - otherwise the machine will either ignore some of the elements or begin to “jump” the needle on the canvas. In this article, we will look at how to avoid typical mistakes when transferring an image to an embroidery module, what settings affect the quality of the result, and why even experienced craftsmen sometimes get “displaced” embroidery.

The first step is to check the compatibility of the file with your machine model. For example, Brother works with .PES and .PEX, and Janome — with .JEF or .SEW. If you upload a file in the wrong format, the machine will either give an error E6 (unreadable design), or automatically converts it with distortions. Next, we analyze the resolution: for embroidery, 300 dpi is optimal, otherwise the contours will be “stepped”. And finally - the color palette: if there are more than 15 shades in the picture, you will have to manually edit them in a program like Wilcom EmbroideryStudio or PE-Design, otherwise the machine will replace similar tones with the same thread color.

1. What file formats do embroidery machines support?

Not all graphic formats are suitable for embroidery. The main mistake newbies make is trying to load it into the machine. .PNG or .JPEG directly. These formats contain pixel graphics, and the embroidery module works with vector commands, where each stitch is programmed as a coordinate. Therefore, the image must first be converted into a specialized format.

The most common formats for embroidery machines:

  • 🔹 .PES - universal format for Brother, Babylock, Bernina (includes information about colors and stitch sequences).
  • 🔹 .DST - outdated, but still used format (stitch coordinates only, no colors).
  • 🔹 .JEF - for cars Janome and Elna (supports up to 256 colors).
  • 🔹 .VP3 - format for Husqvarna Viking and Pfaff (contains data on stitch density and types).
  • 🔹 .XXX - used in Singer (compatible with most modern models).

If your machine does not support the required format, you will have to use a converter (for example, Embrilliance Essentials or SewArt>). Important: when converting from .DST in .PES colors may be off - they need to be checked manually in an embroidery editing program.

⚠️ Attention: Files with the extension .EXP (for Melco) and .CSD (for Singer) may contain editing protection. If the machine gives an error E18 (“file is locked”), try opening it in Wilcom and save again without protection.

2. Preparing a picture: from scan to vector design

In order for the machine to reproduce the image correctly, it must be converted into a vector format with clear contours. The following programs are suitable for this:

  • 🖌️ Adobe Illustrator (tool Image Trace for vectorization).
  • 🖌️ Inkscape (free analogue, function Trace Bitmap).
  • 🖌️ CorelDRAW (suitable for complex designs with gradients).

After vectorization, check:

  1. No “holes” in the contours (the machine will skip these areas).
  2. Minimum number of knots (too many - the embroidery will be “torn”).
  3. The size of the design does not exceed the working area of the hoop (standard - 100x100 mm for household machines).

If the picture contains small details (for example, text or thin lines), increase their thickness to 0.5–1 mm, otherwise the machine will replace them with a solid fill. To check, use the simulation mode in the embroidery program (View → Stitch Simulation in PE-Design).

The problem is the design Reason Solution
Offset contours Mismatch of layers in a vector file Merge all paths into one layer (Path → Combine)
"Ladder" on curves Too few anchor points Add nodes manually or increase vectorization resolution
Missing elements The outline color matches the background Change the stroke color to contrast
Distortion of proportions Incorrect export settings Set fixed aspect ratio

If you are embroidering a portrait, use the technique shadow stitch (stipple stitch) for smooth transitions. B Wilcom it is available in the menu Stitch Types → Fill → Stipple.

3. Setting up the sewing machine before embroidery

Before loading the file into the machine, check the key parameters:

Install the embroidery module (for models with a removable table)

Check the tension of the upper thread (optimally 3–4 on the scale)

Thread the bobbin thread (the color must match the first color of the design)

Calibrate the hoop (distance between teeth - 1.5 mm)

Update the firmware (relevant for Brother PR1055X and newer)

-->

Pay special attention to setup stitch density. Too high a density (more than 0.4 mm) will lead to:

  • 🧵 Tightening of fabric and deformation of design.
  • 🧵 Thread breakage (especially when using metallized threads).
  • 🧵 Engine overheating (the machine may turn off with an error E2).

For cotton fabrics, the optimal density is 0.3–0.35 mm, for knitwear — 0.25–0.3 mm. In the program PE-Design Density can be adjusted in the menu Edit → Object Properties → Stitch Density. If your design contains large fills, use traction compensation (Pull Compensation) at +0.3 mm to avoid thread sagging.

⚠️ Attention: When embroidering on non-woven fabric or skin disable automatic thread trimming (Thread Trim: Off). Otherwise, the machine will break the thread after each color block, which will lead to “tails” on the wrong side.

4. Common mistakes and how to fix them

Even with proper file preparation, embroidery may not go as planned. Let's look at the most common problems and their solutions:

🔴 Design offset

If the picture “moves out” during embroidery, the reasons may be as follows:

  • 📏 Loose hoops (check the fastening screws).
  • 📏 Worn out drive belt (relevant for cars over 5 years old).
  • 📏 Mismatch between file format and firmware (update machine software).

Solution: before starting embroidery, run a test design (for example, a 10x10 mm cross) and check the coordinates match. If the misalignment persists, calibrate the hoop in the service menu (Settings → Calibration).

🔴 Broken thread

Most often the thread breaks due to:

  • 🧵 Incorrect threading (check the thread path from the spool to the needle).
  • 🧵 Dull or bent needle (replace with Embroidery Needle 75/11).
  • 🧵 Tension too high (reduce by 0.5–1 division).

Critical: If the thread breaks when changing colors, the problem is improper pruning. In the machine settings (Thread Cutting) select mode Manual and cut the thread manually with scissors.

🔴 “Bubbles” on the fill

The “bubbles” effect (uneven areas in large fills) occurs due to:

  • 🌊 Incorrect stitch direction (use Radial Fill for round elements).
  • 🌊 Too long stitches (maximum 4 mm for cotton).
  • 🌊 Incorrect fabric stabilization (for knitwear, use water-soluble interlining).
How to eliminate "ladder" on curves

1. In your design program, reduce Max Stitch Length up to 2.5 mm.

2. Increase the number of anchor points in the vector contour (but not more than 50 per 1 cm).

3. Use the mode Smooth Stitch (if your car model has it).

4. For complex curves, replace the fill with Running Stitch with a density of 0.2 mm.

5. Choice of threads and fabric: what affects the result

The quality of embroidery depends 40% on the materials. For beginners we recommend:

Material Recommendations What to Avoid
Threads
  • 🧵 Madeira Polyneon - for bright designs.
  • 🧵 Gütermann Sulky - for delicate fabrics.
  • 🧵 Brother Bobbin Thread - for the lower thread.
 Cheap threads (for example, "Ideal") - sheds and fluffs.
Fabric
  • 👕 Cotton (density 150–200 g/m²).
  • 👚 Fleece (with non-woven lining).
  • 👖 Denim (needles 90/14).
 Stretchable fabrics without stabilizer (knitwear, jersey).
Stabilizer
  • 📄 Tear-Away - for dense fabrics.
  • 💧 Water-Soluble - for lace and transparent materials.
 Using paper instead of stabilizer.

For metallized threads (Madeira Metallic) Reduce the embroidery speed to 400 stitches/min and use needles with enlarged ear (Metallic Needle 80/12). If the thread still breaks, lubricate it silicone grease (for example, Sewers Aid) before refueling.

💡

Never use for embroidery sewing threads (for example, "Gamma" or "Maxi"). They do not have a protective coating and wear out quickly, clogging the shuttle of the machine with lint.

6. Step-by-step instructions: from picture to finished embroidery

Algorithm for transferring an image to fabric:

  1. Scanning/vectorization:
    • Open the picture in Inkscape.
    • Apply Path → Trace Bitmap (mode Brightness Cutoff).
    • Simplify the outlines (Path → Simplify, threshold - 0.5).
  2. Conversion to embroidery format:
    • Import the vector into PE-Design.
    • Assign stitch types:
      • 🔹 Outlines - Running Stitch.
      • 🔹 Filling - Tatami Fill.
    • Export to .PES (for Brother) or .JEF (for Janome).
  3. Preparing the machine:
    • Install the hoop and secure the fabric with the stabilizer.
    • Thread the thread according to the diagram (for Brother Innov-is see page 24 of the manual).
    • Select file from menu Design → Select.
  4. Embroidery and control:
    • Run a test fragment (10% of the design).
    • Check the thread tension on the wrong side (there should be even stitches without loops).
    • If necessary, adjust the density in the machine settings.

If the design contains more than 10,000 stitches, break it into parts in the program (Split Design in Embrilliance). This will prevent the machine's memory from being overloaded (error E7 in Brother).

7. How to avoid mistakes when embroidering multiple times

If you plan to embroider the same picture several times (for example, for sale), follow the rules:

  • 📌 Save threading pattern (photo or diagram) for each color.
  • 📌 Use the same stabilizer for all copies (even different batches).
  • 📌 Check it out needle wear after every 5 hours of work (a blunt needle will move the stitches).
  • 📌 Calibrate your hoop once a month (instructions on page 45 of the manual Janome MC500E).

For serial embroidery, we recommend creating test sample on the same fabric as the main order. This will help identify:

  • 🔍 Distortion due to stretching of the material.
  • 🔍 Thread colors do not match the original (take a photo of the sample in daylight).
  • 🔍 Stabilizer defects (for example, heat-away may leave marks when ironing).
💡

To speed up your work, save frequently used designs to a USB flash drive in a folder MyDesigns. Cars Brother and Janome support quick access to files through the menu Favorite.

8. Maintenance of the machine after embroidery

After completing the work, be sure to:

  1. Remove dust and lint from shuttle mechanism (use a mini vacuum cleaner or a brush).
  2. Lubricate moving parts machine oil (1 drop on hoop bearings).
  3. Check thread tensioner for burrs (replace if necessary).
  4. Clear needle plate from threads (use a plastic scraper).

If the machine makes unusual sounds (creaking, knocking), the reasons may be as follows:

  • 🔧 Wear of the drive belt (replacement every 3-5 years).
  • 🔧 The thread gets into the gear (disassemble the shuttle according to the instructions).
  • 🔧 The guide hoops are dirty (wipe with alcohol).
⚠️ Attention: Never use to clean a machine. WD-40 or other aerosol lubricants. They leave a sticky residue that attracts dust and accelerates wear of mechanisms. Suitable for embroidery machines only seiner oil (for example, Brother SA171).

FAQ: Answers to frequently asked questions

🔹 Why does the machine “skip” stitches in the design?

This happens due to:

  • Incorrect needle type (embroidery requires Embroidery Needles with a pointed end).
  • Speed too high (reduce to 500–600 stitches/min).
  • The shuttle is dirty (disassemble and clean from lint).

Also check if the mode is enabled Jump Stitch Trim - it can cut the thread between close stitches.

🔹 Is it possible to embroider on knitwear without a stabilizer?

No. Knitwear stretches under the weight of the stitches, which leads to:

  • Distortion of design proportions.
  • Displacement of threads on the wrong side.
  • Stitches break when worn.

Minimum option - water soluble film (Sulky Solvy), but for dense designs it is better to use adhesive interlining.

🔹 How to transfer embroidery to leather or suede?

For skin:

  1. Use skin needles (Leather Needle 90/14).
  2. Reduce stitch density to 0.2–0.25 mm.
  3. Paste on the wrong side adhesive stabilizer (Floriani No-Show Mesh).
  4. Embroider at low speed (300–400 stitches/min).

For suede add upper stabilizer (water-soluble topping) to prevent stitches from sinking into the pile.

🔹 Why don’t the colors on the machine screen match the real threads?

This is due to:

  • The difference in the color profiles of the monitor and the machine (calibrate the screen).
  • Using non-original threads (for example, Chinese analogues Madeira may differ by 10–15 tones).
  • Incorrect lighting settings (in the program PE-Design select View → Realistic Colors).

Solution: print before embroidering color test (function Color Chart in most embroidery programs) and compare with real threads.

🔹 How to embroider small details (text, outlines)?

For text and thumbnail elements:

  • Use chain stitch (Chain Stitch) instead of filling.
  • Increase the density to 0.5 mm (but no more!).
  • Replace the standard thread with polyester (Madeira Polyneon) - it is thinner and stronger.
  • For contours less than 1 mm thick, use Running Stitch with double passage.

If the letters still run together, increase the font size to 6–8 mm or replace it with vector (for example, Embroidery Fonts from Anita Goodesign).
