Can 4OVER4 print variable data like sequential numbers, barcodes, or QR codes?

Yes, 4OVER4 prints variable data on roll labels, so every single label in a run can carry its own unique information.

• Consecutive numbering: sequential serial or ticket numbers, including numbered limited editions and tracking or inventory serials.
• Barcodes: UPC and other retail or inventory codes.
• QR codes: a different scannable code on each label.
• Other variable fields: names, dates, or batch details that change per piece.

File setup matters on variable runs: supply your design file plus a clearly labeled data file (a spreadsheet with one row per piece works well), build artwork as one unit per page rather than multiple designs on a single page, and keep the variable field in the same position on every version so the print stays aligned. Because variable-data jobs are custom, submit your specifications (size, quantity, stock type, deadline, design files, and the data or numbering range) through a custom project request or contact the support team; the estimations team reviews the request and quotes pricing to your exact data, quantity, and label size.

Variable data also works on cards, such as numbered or barcoded card sets. Mark exactly where the number or barcode sits in your file, and note any special requirements in the order comments.
