Frequently Asked Questions

Jewelry labels (often called "Butterfly" or "Tail" tags) require high precision. Because the labels are small and the rolls are narrow, follow these steps to ensure your barcodes align perfectly within the 3-column layout. 

1. Load Your Media Correctly Place your 3-column jewelry roll in your thermal printer (like a Zebra or TSC). Ensure the movable media sensor is positioned directly under one of the labels (not the gap between columns) to detect the "top of form." 

2. Configure the Generator Settings Navigate to the Label Printer section on our tool and use these specific settings for standard 3-column jewelry rolls: Roll Width: Set to the total width of your liner (usually 80mm to 100mm). Columns: Select 3 Columns. Label Dimensions: Measure a single tag. A common size is 30mm x 10mm. Gaps: Set the Column Gap to 2mm and the Row Gap to 3mm. 

3. Design for Small Spaces Symbology: Use Code 128 or Code 39. For jewelry tags, keep your SKU short (e.g., 5-8 characters) so the barcode doesn't become too wide to scan. Font Size: Use 6pt or 7pt for the price or item name to ensure it stays within the printable area. Barcode Height: Set the height to approximately 30px to 40px to leave room for text above. 

4. The "Test Print" Step Before printing a full batch from your Excel file: Enter three test codes manually. Click Export PDF. In your PDF print settings, ensure "Scale" is set to 100% or "Actual Size." Do not use "Fit to Page," as this will shrink your barcodes and cause misalignment. 

5. Troubleshooting Alignment Barcodes drifting right? Increase your "Left Margin" by 1mm in our settings. Printing over the gap? Check that your "Column Gap" matches the physical space on your roll exactly. 

TIP : If you are using Resin Ribbons for your jewelry labels, increase your printer's Darkness setting to 20 in the driver. This ensures the fine lines of the barcode don't smudge on the synthetic jewelry material.
