When we were researching Ink Control Systems capable of delivering the exact pre-calculated volume of ink to the plate, we found only one…

I.Mer Remote Ink Control System
The I.P.C – Divided Ductor Roller

De-Skill Ink Presets with a Remote Ink Control System from I.Mer

Unlike other Remote Ink Control Systems, I.Mer’s Divided Ductor Roller was developed for the VERY demanding two piece can industry. Not only did it survive this harsh environment, it thrived being retrofited to over 85 can decorators.

The main benefit of a divided ductor over conventional Remote Ink “Key” Control Systems, is the ability to transfer the exact amount of ink required in any zone without compromising other areas of the plate.

With a Divided Ductor it is possible to print solids & spot color side by side. No more spiral ductors for light coverage, or wrenches for heavy.

The operation of the Divided Ductor removes the variables associated with existing remote ink control systems.

Ink “key” system variables such as, operator sweep control, key wear, key calibration, sticking keys & hydraulic lift are all eliminated. 

How It Works

 The Divided Ductor System utilizes a fixed blade to establish a uniform ink film thickness on the fountain roller.

As the sweep is a fixed percentage of press speed, any hydraulic lift of the fountain roller, or film thickness variation, is repeatable & can easily be accommodated using offset parameters.

Now that a consistent ink film thickness has been established, extremely precise ink feed can be accomplished by automatically varying the dwell time of the divided ductor roller segments against the fountain roller. 

If you look closely at the fountain roller you can see the ink profile reflected in the ink film.

What You Are Watching..

  • To the left you can see the ink fountain has a small sausage of ink maintained by the ACC system.
  • The fountain is lined with a thin film and enclosed with magnetic end cheeks. (See Auto Fountain Cleaner)
  • The fountain roller is carrying a uniform ink film thickness across the entire width.
  • The un-energized Divided Ductor segments maintain contact with the ink train.
  • When energised the segments contact the fountain roller.
  • The time, individual ductor segments contact the fountain roller, is dependent upon the image profile, predetermined by the Area Reader.
  • Contact will be longer for areas of heavy coverage.
  • In areas of no coverage the segments do not move.
  • While in very light coverage the segments energize intermittently.

Designed using the KISS philosophy the Divided Ductor system eliminates many of the variables associated with ink key systems.
Pneumatically energized with spring return there are only 4 moving parts/section. The Divided Ductor system is a perfect example of less equals more.

I.Mer have successfully de-skilled not only the operation of ink setting but also the functionality of the system itself!
