Our labels are designed for library applications and are compatible with all library systems. We offer adhesives formulated for automated library circulation and top coatings designed to withstand UV and are suitable for archival requirements. All our products come with a 100% satisfaction guarantee. Samples are available. Every purchase starts with a proof for your approval. If you purchase barcodes elsewhere we suggest that you always use a barcode expert. Even slight distortion, deviation from industry specifications or bluriness of the printed bars can render poor readability and user frustration. Some poor barcodes will work okay at close range (3-4 inches) but will fail on longer range scanners used for self-checkout.
