SMITH PPI COMMERCIAL PRINTING

Spraymatic G4 - The Ultimate in Automated Dampening Controls for Commercial Offset Printing Applications

High Speed Pulsed Dampening is now available for wide range of commercial printing application, including forms printing with standard and U.V. inks, Insert and Tabloid newsprint, heatset on coated stock with standard or U.V. Inks and packaging with standard or U.V. Inks.

Spraymatic G4 provides the advanced pulse speed and precise spray pattern required for continuous roller coating and fountain solution metering. Advanced Pulse Speed (APS) Controls achieve film coating results not previously available in spray dampening systems. Now, ink density and print quality may be maintained at levels equal to Continuous or Dahlgren type dampeners. Heatset, long run presses and forms presses are achieving excellent results using the Spraymatic G4 system controls.

Spraymatic G4 PLC Controls

Spraymatic G4 controls provide comprehensive water distribution with infinite adjustments of each spray nozzle. Precision solenoid valves are adjustable in .50 millisecond increments. Pulses per minute may be adjusted from 0 to 3,500! Independent Non Linear curves provide for continuous quality printing by allowing for set point differentials to increase or decrease water output as the press accelerates or decelerates. Values are individually stored and quickly recalled for presets of previous jobs. Automatic, adjustable flood time controls allow for very fast start ups with minimum waste copies!

Spraymatic G4 Controls iclude self-check diagnostics. Each time the system is turned on, every solenoid valve is automatically pulsed to check operation. Any malfunction is immediatley displayed as an error, so the bar can be serviced. In addition, if any bar is missing from the press, an error message is displayed with the location noted.

Windows® based, Spraymatic G4 Controls are the fastest, easiest to use controls available for spray dampening. Adjustments, small or wide range, can be made quickly and conveniently. Press set ups are easily changed for different press configurations. Bar selections are made by pointing to the unit bar to be changed. Non linear curves have on-screen display to view the entire ramp speed range and quickly change it. Alpha numeric job file directories allow for quick reference and job recall. Color coded keys and press units allow the operator to easily set up and adjust jobs.
