Integrated Valve Ink Jet

Diagraph's Integrated Valve (IV) marking and coding technology that is found in our drop on demand large character inkjet printers, deliver highly readable alphanumeric codes and logos where achieving the lowest cost per mark is important for the application. These dot matrix, valve jet case coders are engineered for reliable, low-maintenance, 24/7 operation in harsh industrial environments.

The IV case coding technology series allows manufacturers to manage two independent production lines with up to 16 print heads daisy-chained to a single controller. It is perfect for coding applications that require fonts as small as 3/16" and as large as 2". Substrates that pair perfectly with the IV series include corrugate, plastic, metal, glass, drywall, wood products, pipe and carpet.
