New! EPG AC Actuator for Telecolor Consoles Now Available


EPG designed the original Harris Ink Key Actuator back in 1974 with millions sold worldwide!


Parts for these ink key actuators are now obsolete so EPG has redesigned this actuator to be a drop in, plug & play replacement for the original Telecolor I & II ink control systems.

The New EPG AC Actuator uses evolutionary technology

and drops directly into existing presses with no

electrical modifications needed.

The EPG AC Actuator extends the life of your offset press and is driven by Telecolor I and II, CPTronic, and Omnicon ink control consoles that had shipped with most Harris, Heidelberg, and Goss offset presses.

The EPG AC Actuator is available for Harris, Heidelberg & Goss presses:

  • M110 • M130 • M200 • M300
  • M400 • M600 • M1000 •
  • V15 •V25 • V30 • V130
  • Mercury and others using ink control consoles from
  • Telecolor I
  • Telecolor II 
  • CPTronic 
  • Omnicon  

Failing Ink Keys

Failing ink keys – the most pronounced symptom of actuator burn-out – is also the most common problem affecting these presses’ ink control systems.  The situation has worsened considerably, as printing and packaging companies are at the mercy of a dwindling supply of old and refurbished actuator units. The motors are obsolete and unavailable, and the potentiometers are no longer manufactured. Essex Products Group has the only viable solution to this growing challenge.

An Ink Key with some History

Harris contracted Essex Products Group to design the original AC Ink Key Actuator in the 1970s, and since then millions have been installed on Harris-Heidelberg presses around the world.  It was the Harris Ink Key that prompted EPG’s entry into the remote ink control market when EPG used this experience to create its own Smart Fountains using new and improved actuator designs.  

Because of the vast numbers of these Ink Keys still out there in presses today, EPG has revisited this product and refreshed the internal components and electronics with the modern, drop-in EPG AC Actuator replacement, which includes a 2-year warranty.  This technology is the true successor to the AC actuators installed in these legacy presses, and will “plug and play” for immediate functionality.
