🔤 Glossary Index

Term Definition
CIJ Continuous Inkjet – a high-speed printing method where ink is continuously expelled and selectively deflected to form characters
Breakoff The point at which the ink stream breaks into droplets — essential for accurate charging and deflection
Charge Electrode A small component that applies voltage to each droplet so it can be deflected correctly
Deflector Plates High-voltage plates that steer charged ink droplets into position to form characters
EHT Extra High Tension — refers to the high voltage system in the printhead that powers the charge and deflection system
Gutter A return channel that collects uncharged ink droplets and recycles them into the system
Viscosity The thickness or resistance to flow of the ink; controlled by the printer through makeup solvent addition
VMS Viscosity Monitoring System — automatically checks and adjusts ink viscosity
Trigger Mode The setting that tells the printer when to start printing (e.g. via photocell, encoder, or continuous)
Blocking Time A pause after each trigger to prevent duplicate prints on the same product
Photocell A light sensor used to detect when a product is in position for printing
Encoder A rotary sensor that tracks conveyor speed and adjusts print timing accordingly
Restrictor A precision orifice that regulates ink pressure and stream shape before breakoff
Umbilical The flexible cable bundle that connects the printhead to the printer body, carrying fluids and power
Clean Ink System A full flush routine that removes old or contaminated ink and resets the system
Fill Mixer A maintenance function that primes the ink system with the correct solvent/ink mix
Park Routine Safely prepares the system for shutdown by draining and sealing critical components
Firmware The internal software that runs the printer’s logic and controls functions
Message A saved print template that may contain text, dates, counters, barcodes, or logos
Field (Variable) A placeholder in a message that updates per print — e.g., batch number or serial code
