Variable data printers are integrated into production lines and specialize in printing variable data (i.e. variable information or VDP) onto products and packaging; such as barcodes, batch numbers, expiration or shelf life, production dates, product descriptions, weights and other data. Variable data provides detailed and specific information about production that can be used to help improve supply chain visibility and facilitate rapid product recalls, so Videojet printers are designed and engineered to avoid this critical spray. errors in the coding process that may affect the effective traceability of the product.
