DELTA Damping Systems
How it Works
The unique Delta design utilizes helical gears and positive roller settings to drive the dampening form roller at a slower surface speed than the plate cylinder. The differential motion, called the “Delta Effect” wipes away the foreign particles that cause hickeys, while continuously allowing a fresh charge of ink to the plate.
Features
- Delta Dampening System retrofits are available for virtually every major press model
- Form roller operates at a lower surface speed than that of the plate
- Dampening form roller is separate from the inking system, allowing for the retention of all ink form rollers
- Separate variable-speed drive motor and water control adjustments
- Thin film of precisely metered dampening solution is applied as required across the plate
- Exclusive Epic air-activated oscillating bridge roller reduces ghosting
- Instantaneous control of ink/water balance
