The Award Winning Technology

2021 FTA Technical Innovation Awards

For over 20 years, the FTA Technical Innovation Award has recognized the most innovative and impactful technologies for the ever-evolving package printing and converting industry. The recipients of the Technical Innovation Award are deemed by a panel of industry experts to have the potential to change flexography’s future for the better.

InkSight fundamentally changes the nature of the flexo printing process, from initial job setup all the way to jobs that, once delivered, secure a clear path to repeat business… It can produce a change in the very culture of the flexo industry by adding job-length consistency, accuracy and efficiency.


2021 Gravure Awards for Sustainable Packaging by ERA

Rheonics was awarded 2021 Sustainable Packaging Innovation Award by European Rotogravure Association for their new inline viscometer technology for ink viscosity measurement in the press.

Printers can achieve unmatched color accuracy and quality with the InkSight system and ColorLock™ software –which is designed in collaboration with printers, for printers. Viscosity automation and predictive tracking control with InkSight reduces waste and materials consumption, as it increases efficiency and improves quality.

Randy Buchholz, Engineer

“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.”

Todd Luman, Manager

“In my professional opinion, there is not another viscosity control system on the market place today that can match the results we have experienced to date with the Rheonics SRV sensor. It is a new technology that separates itself from the others. I have not had the same level of performance as displayed by the Rheonics InkSight controller due to their technology product advancements.”

Bert Verweel, Owner

“The increased confidence on control over print and color quality with the InkSight has enabled us to take on higher margin and higher quality jobs where the brand owners have very strict color specifications. With this system, we strive for low dE2000 values in order to keep the quality level as high as possible and making it difficult for the competition.”

Rheonics Printing Solution

Print to spectrophotometer standards.

Color and Rheonics is synonymous with InkSight and color control. The printing process is set to spectrophotometer standards, InkSight measures and controls viscosity within 0.5 cps : 100 times greater resolution than average efflux cups enabling inkSight control color forward of the spectro track. InkSight Colorlock precisely locks color from start to finish on every job with repeatable results.

Asset 4

• Rheonics SRV viscosity sensor measuring element is sealed within the sensor head, protected from fluid ingress providing precise measurement with consistent color control

• The sensor washes up with your press, if ink lines are dirty inkSight alerts the operator

inkSight System Main Components

• Rheonics Predictive Tracking Controller
• Smart View Press Console
• SRV sensor on each station
• Pneumatic valve for solvent control
• Auto-wash system (when needed)

You can take the cup out of the equation.

100x more accurate than a zahn, shell, din or ford cup – the SRV Sensor is repeatable to 0.1 cps (equivalent to 0.001 second on a cup) and can enable your printing process to spectrophotometer standards.
