Industrial metal components require permanent, high-contrast coding that can withstand extreme production environments, including heat, oil, abrasion, and outdoor exposure. RN Mark industrial inkjet printers are designed for reliable coding and marking on a wide range of metal surfaces such as aluminum plates, steel tubes, sheet metals, and aluminum extrusions. With advanced large character (LCM) and high-resolution inkjet technology, RNJet systems enable precise printing of logos, batch numbers, serial numbers, part codes, barcodes, and traceability information directly onto metal parts. Whether you need small character marking or large format identification, our printers deliver sharp, durable, and readable prints without contact or surface damage.
Metal sheet marking requires precise, high-adhesion printing that remains readable in demanding industrial environments. The RNJet H1 thermal inkjet (TIJ) printer provides a reliable solution for coding and marking on metal sheets, aluminum plates, steel components, and fabricated parts.
With high-resolution TIJ technology, RNJet H1 enables accurate date coding, lot coding on metal, batch coding, serial number printing, and barcode marking directly onto metal surfaces. These markings are fast-drying, smudge-resistant, and designed to withstand exposure to oil, heat, and handling during production and logistics.
Ideal for small character marking, RNJet H1 supports variable data printing such as manufacturing date, expiry date, shift codes, and traceability information. Its compact design and easy integration make it suitable for conveyor-based production lines, ensuring consistent, high-speed metal coding without downtime.

RNJet H1 industrial inkjet printers deliver high-resolution, durable coding on metal components such as metal sheets, steel tubes, and aluminum parts. Achieve clear date coding, lot coding, and traceability marking even on oily, smooth, or rough metal surfaces.
