What is a lot number?

Print Lot Number on Products with Videojet coding and marking solutions

Videojet specializes in inkjet, laser, thermal transfer and other types of lot number printers, as well as labelers to apply lot numbers to packaging.

A lot number is assigned to a batch of products from a particular manufacturer. Numbers, letters or bar codes can identify a lot number for a set of products sharing certain characteristics of production. A lot number can help ensure product traceability and serve as confirmation of the identity of products at various stages of production and throughout the supply chain

Lot number printers and lot coders are terms commonly used by operators and maintenance teams for coding machines used to print directly on products or packaging, or for machines that print and apply a label containing the lot number onto a product.

Videojet solutions for printing human and machine-readable lot numbers include continuous inkjet, thermal inkjet, laser marking, thermal transfer and case coding printers. Considering the surface to be printed or marked (e.g. plastic bags, cardboard boxes, cables, heat shrinkable sleeves, pouches, kraft paper bags, PET bottles, metal or almost any other material), Videojet can help you select the ideal lot number printer.

Specialized Videojet inks are formulated for printing on frozen foods, meat, baked goods and snack packaging as well as pharmaceutical and medical device packaging and more.

Helping to reduce a manufacturer’s environmental footprint, laser marking systems use no inks or fluids. Videojet offers wide range of laser lenses, powers and technology types for marking on cases, cartons, metal, glass, cardboard, paper and plastic.
