American Packaging Corporation uses the SRV and InkSight system to optimize packaging printing on their rotogravure lines



Printing quality and color control in the packaging printing rotogravure market segment  


  • Cup viscosity measurements do not have the accuracy to counter viscosity related printing issues inside the press with simplicity
  • Skilled printers left/promoted off press and the skill level of new printers diminished, making viscosity management with cups unreliable.
  • With other automatic viscosity management systems, the operators lost confidence in the performance of these systems (incorrect dosing) and basically stopped using them.


  • The Rheonics SRV viscometer gives ultra-stable, repeatable and accurate measurements without needing any re-calibration
  • InkSight sensor was positioned in print unit with extremely tight setpoint tolerance
  • PID control is phenomenal, and engineers could control almost any valve style with success.

The User Testimonial | Rheonics RPS InkSight | American Packaging Corporation (Packaging Printing)

Since installing the new InkSight viscosity control system on one of our rotogravure lines, we’ve seen some impressive results. The PID control is phenomenal, and we could control almost any valve style with success. It can maintain an extremely tight setpoint tolerance. The built-in data logger is an excellent feature that our process engineering team finds very useful. Also, Rheonics ability to service us remotely in a timely manner has been instrumental in the successful commissioning of this system. We are looking forward to installing our second system soon and we thank Rheonics team for their commitment to our success.
