Drop-On-Demand Coders

A drop-on-demand (DOD) inkjet printer works by ejecting discontinuous ink droplets directly onto the substrate to be marked. In essence, the printhead dispenses ink only when needed. A heating element inside the printhead creates pressure to force the droplet of ink out the nozzle and onto the printing surface. The resulting print image is composed of these individual “on-demand” ink droplets.

Drop-on-demand inkjet printers are ideal for large character printing due to the nozzle diameter size. Nozzles on the printhead are controlled individually and can create extremely fine droplet sizes. Drop-on-demand inkjet printers can utilize a wide variety of inks to mark on many different types of surfaces. Suitable for challenging production environments that have dust, shocks, and vibrations.

DOD inkjets offer robust and reliable large character printing at a lower cost than other inkjet technologies.

Matthews’ VIAjet™ V-Series

Powered by MPERIA®, Matthews’ VIAjet™ V-Series marking system features our reliable Drop-on-Demand (DOD) valve technology which marks on porous and non-porous substrates including metal, paper and pulp, wood, concrete and plastic. Matthews’ DOD valve printheads are considered the fastest in the industry, marking products at speeds up to 800 fpm (244 m/min), with the longest life—over 6 billion firings per head.

The V-Series features large character printing, ranging from 1/8” to 5” (3 mm to 127 mm) and the capability to stack printheads for large logos. These features, combined with its rugged design, make V-Series ideal to meet the demands of extreme environments such as building products, steel mills and other industrial environments.

The MPERIA® controller effectively manages messages and settings for multiple printers across one or several production lines or plant locations. An extensive selection of pre-formatted and configurable counters, batch controls, user-defined text fields and barcode symbologies makes message creation and selection a breeze with the intuitive touchscreen interface. Seamless integration with ERP/MRP/WMS systems helps to reduce coding errors. Best of all, MPERIA® is expandable, allowing you to add other printheads or other print technologies as needed, promising a sound secure investment. Our DOD valve technology and MPERIA® controller are connected by V-Link, an enclosed module featuring an internal power supply and printhead driver board. Each V-Link drives up to 32 valves (1-4 printheads). Multiple V-Links can be stacked and networked through MPERIA®, providing a flexible and scalable system for small or very large applications.
