2. Core Bernina embroidery file formats: ART, EMB, and JAN Explained

Bernina embroidery thrives on a trio of powerhouse bernina embroidery file formats: ART, EMB, and JAN. Each serves a distinct purpose, and knowing their ins and outs can be the difference between creative frustration and embroidery bliss. Let’s break down what makes each format tick, how they interact, and why file "grades" matter for your designs.

2.1 ART Format: Bernina's Proprietary Powerhouse

The ART format is the crown jewel of Bernina’s embroidery universe—think of it as the Swiss Army knife for design editing and machine compatibility within the Bernina ecosystem.

Technical Breakdown:

• Proprietary Format: ART files are developed exclusively for Bernina, offering the deepest level of editing and design control.
• Data Rich: These files store stitch coordinates, thread colors, object outlines, auto-spacing, and metadata—everything you need for precise, intricate work.
• Version Support: From legacy ART (A730/A200) to ARTx0 and ART42, newer Bernina software (like V9) supports the latest iterations, while older versions (V1/V2) are now read-only.

2.2 EMB Format: Wilcom Compatibility Bridge

EMB files act as the diplomatic envoy between Bernina and the broader embroidery world, especially for those leveraging Wilcom’s digitizing power.

Technical Role:

• Third-Party Origin: Created by Wilcom, EMB files are widely supported by Bernina V9 and serve as a robust bridge for importing and exporting designs.
• Data Content: EMB files retain stitch data, thread colors, and basic object properties, though they lack some of the advanced metadata found in ART.

2.3 JAN Format: Janome/Elna Cross-Compatibility

JAN files open the door for those working in mixed-brand environments, offering basic interoperability between Bernina and Janome/Elna machines.

Technical Overview:

• Read-Only in Bernina V9: While Bernina V9 can read JAN files, it cannot write or fully edit them.
• Data Content: These files include stitch coordinates and thread basics, but lack the rich object properties of ART and EMB.

Key Takeaway: Stick with Grade A files (ART, EMB, JAN) for maximum flexibility—especially if you plan to resize, recolor, or remix your designs.

 

3. File Conversion Workflows: Preserving Design Integrity

Getting your masterpiece from screen to stitch often means converting between formats. The good news? Bernina’s software makes this process surprisingly smooth—if you know the right steps and pitfalls to avoid. Here’s how to ensure your designs survive the journey intact.

3.1 Step-by-Step: Converting ART to EXP and Third-Party Formats

Bernina’s Conversion Tools: Your Digital Swiss Army Knife

• Start in ART: Open your design in Bernina software (V8/V9). ART is your "master file"—preserve it for future edits.
• Batch Conversion: Select one or multiple designs in the embroidery library. Use the Manage Designs > Convert Selected Designs feature for efficiency.
• Choose Your Target Format:
  • Bernina USB EXP: Ideal for home machines. Produces three files: .EXP (stitch data), .INF (thread colors), and .BMP (preview image).
  • Melco EXP: Commercial format—no thread color data, so your design may look like a psychedelic experiment on-screen, even if it stitches fine.
  • PES/DST: For Brother, Babylock, or commercial machines, select these from the conversion dialog. Always check your machine’s max hoop size (e.g., 6.5" x 10.5" for 790 PLUS).

Critical Tips:

• Thread Colors: Use Bernina USB EXP to preserve color info. Melco EXP defaults to generic colors.
• File Organization: Keep original ART files in a separate folder. Store converted files in "My Machine Files" for easy access.
• Preview and Test: After conversion, preview designs in your machine’s software and run a small test stitch to confirm alignment and density.

4. Machine Compatibility Matrix: From 830 to Legacy Models

Navigating Bernina’s file formats is only half the battle—knowing which machines support which formats (and how to get your designs onto them) is where the real magic happens. Let’s break down compatibility for both modern and legacy Bernina models, so your designs land exactly where you want them—no surprises, no stitch-outs gone awry.

4.1 Modern Machine Support (790 PLUS/Bernina 830 embroidery machine)

Modern Bernina embroidery machines, like the 790 PLUS and Bernina 830 embroidery machine, are built to handle today’s most versatile file workflows. Here’s what you need to know:

Supported Formats:

• ART: While ART remains Bernina’s proprietary editing powerhouse, most newer machines (like the 830) focus on reading stitch-ready formats for actual embroidery.
• EXP: The universal hero—EXP is the go-to for modern Bernina models. It’s compatible across the 830, 780, 750, 580, 630, and 640, among others.

EXP Subtypes:

• Bernina USB EXP: This is the home-machine format you want. It requires a trio of files for each design:
  • .EXP (stitch data)
  • .INF (thread color info)
  • .BMP (preview image)
  All three files should be copied to your Bernina USB stick for flawless machine recognition and accurate color previews.
• Melco EXP: Used in commercial settings, but beware—it lacks thread color data, so your machine may display wild default colors. The stitches will be correct, but the preview could look psychedelic.

USB Transfer Protocols:

• Use Bernina’s Personal Design USB sticks for best results.
• Always ensure all three USB EXP files are present before transferring.
• Maximum design dimensions for these machines typically cap at 6.5" x 10.5"—stay within these boundaries to avoid stitch errors or design truncation.

Pro Tip: If you’re downloading designs from the web, always convert them to Bernina USB EXP using your software before stitching. This ensures thread colors and previews display as intended, not as a random color wheel explosion.

4.2 Legacy System Compatibility (A730/630/640)

Older Bernina models, like the Artista 730, 630, and 640, come with their own set of quirks and requirements. Here’s how to keep them humming:

Format Requirements:

• A730/200: These models can read both ART and EXP files directly, giving you more flexibility.
• A630/640: These are EXP-only machines—ART files won’t show up at all.

Special Folder Structure:

• For the 630/640, designs must be saved in EXP format and placed inside the \EmbF5 folder on your USB stick. If your designs aren’t showing up on the machine, double-check this folder structure first.

Using the ADX Utility:

• The ADX (Artista Data eXchange) utility is your best friend for legacy machines. It converts ART files to EXP and generates the necessary companion files (.INF and .BMP) for proper display and stitching.
• Even if you’re working with downloads from the internet, running them through ADX ensures compatibility and correct file formatting.

Troubleshooting Tips:

• If your machine doesn’t recognize your USB stick, try creating a simple text file on the stick first—some older models need to “see” any file before they’ll process embroidery files.
• Always check that all three EXP files are present; missing files can cause designs to fail to load or display incorrectly.

 

5. Troubleshooting Common File Errors

Even the best-prepared embroiderer can run into digital hiccups. Whether it’s a missing file or a cryptic compatibility warning, here’s how to diagnose and fix the most common Bernina embroidery file issues—so your creative flow never gets jammed with Bernina hoop alternatives. Enter magnetic embroidery hoops

5.1 Missing INF/BMP Files in EXP Formats

The Problem: Bernina’s USB EXP format isn’t just a single file—it’s a team effort. If the .INF (thread color info) or .BMP (preview image) files are missing, your machine might refuse to load the design, or you’ll see blank previews and wrong thread colors.

Diagnosis & Recovery:

• Check File Integrity:
  • Make sure all three files (.EXP, .INF, .BMP) are present in your design folder and on your USB stick.
• USB Compatibility:
  • Some machines are picky about USB sticks. If your 830 or similar model rejects a stick, try a different one—preferably a Bernina-branded or low-capacity stick.
• Recreate Missing Files:
  • Open your master ART file in Bernina software and re-export as USB EXP. This will regenerate all three necessary files.
• Folder Placement:
  • For legacy models, ensure files are in the correct folder (e.g., \EmbF5 for 630/640).

Pro Tip: If you’ve downloaded a design online and only received the .EXP file, import it into Bernina software and export it again as USB EXP. This will create the missing .INF and .BMP files, restoring full functionality.

5.2 Version Compatibility Warnings in ART Files

The Problem: ART files come in different versions (e.g., ART80 for V8, ARTx0 for V9). Opening a file created in a newer version of Bernina software on an older machine or software can trigger compatibility warnings—or worse, prevent the file from opening at all.

Solutions:

• Update Your Software:
  • If possible, upgrade to the latest Bernina software (V9 supports ARTx0 and ART42).
• Convert for Compatibility:
  • Open the ART file in the latest software and save it as an older ART version if your machine requires it.
• AMT Template Migration:
  • For template files (AMT70/AMT80), ensure you’re using a version that matches your software. V9 supports AMT80/AMT70 for read/write, but older templates (AMT50/AMT60) are no longer writable.
• Third-Party Files:
  • When importing PES or DST files, remember they’ll be converted to ART Grade C—editing will be limited to scaling (up to 10%) and basic stitch changes.

Preventative Measures:

• Always keep your master files in the latest ART format for maximum editability.
• Regularly update your software to avoid version conflicts.
• For older machines, maintain a library of compatible ART versions and templates.

8. FAQ: Bernina File Format Essentials

8.1 Q: Why does the Bernina USB EXP format require three files (.EXP, .INF, .BMP)?

A: The Bernina USB EXP format is actually a set of three files: .EXP (stitch data), .INF (thread color information), and .BMP (design preview image). All three are necessary for your machine to display the correct colors and preview, and to stitch the design accurately. If any file is missing, you may see incorrect colors or no preview at all.

8.2 Q: What's the maximum scaling I can do on imported machine files in Bernina software?

A: When working with non-native machine files (like PES, DST, EXP), Bernina software allows scaling up to 10%. Beyond this, stitch density and coverage may become inconsistent, so for major resizing, always use Grade A files (ART, EMB, JAN) for best results.

8.3 Q: Can I use third-party formats (like PES, DST) directly with Bernina machines?

A: Most Bernina machines require designs in EXP format for stitching. While you can import third-party formats into Bernina software, they'll be converted to ART Grade C for editing—limiting advanced edits. For actual embroidery, always export your final design as Bernina USB EXP to ensure compatibility and accurate color information.

8.4 Q: How do I know if my file is Grade A, B, C, or D?

A: Grade A files (ART, EMB, JAN) retain all design data and offer full editing and scaling. Files converted from outline or machine formats become Grade B or C, losing some editability. You can check the grade in the file's properties dialog within Bernina software.

8.5 Q: What's the best practice for archiving embroidery designs?

A: Always save your original designs in Grade A formats (ART, EMB, JAN) and keep backups in organized folders. This ensures you can return to fully editable versions for future projects or format conversions, keeping your creative options wide open.
