InkSpec eliminates 21 years of guesswork to accurately control viscosity in “real” time with no moving parts and zero maintanance!

Chances are you will find InkSpec’s IIS viscosity control system on any new flexo press installation. They have become the standard for  most OEM press manufactures for absolute accuracy in controlling, monitoring and maintaining viscosity control for maximum print performance!


Installed between the ink pump and printing deck, the IIS viscometer requires NO MOVING PARTS to monitor and control the ink viscosity throughout the print job. The actual viscosity is detected in real time and displayed on the multi-channel InkSpec touch screen Console.

The actual and desired viscosity values are compared and, when necessary,the InkSpec triggers a control valve that injects a predetermined amount of adjuster fluid (solvent or amine solution) to maintain proper viscosity. Each injection is followed by a dwell time of several seconds to ensure thorough mixing of the fluid adjuster, thus avoiding over corrections and flooding of the ink pail. Even while this process is occurring the sensor continues to monitor the ink viscosity and when the dwell period has lapsed the IIS viscometer is ready to apply more corrections as needed. Not withstanding the safety of the Injection / Dwell cycle, an injection time safeguard is also built in to avoid extremely large one-time injections.

The heart of the viscometer uses simple tuning fork technology. The MICRO VIBRATING elements are completely immersed in the ink flow and their resonance is maintained electronically. Using the integrated computer,the viscometer – much like a musical instrument would – emits sound waves in the ink. A specialized detection circuit then analyzes the changes in these waves caused by the tiniest of variations in the ink viscosity. Using proprietary algorithms these variations are translated into numerical data that can be displayed in Centipoises or Seconds. IIS viscometers are designed to work in a multi-channel environment with an InkSpec touch screen Console.

In 2007, InkSpec was awarded the prestigious Flexographic Technical Innovation Award by the FTA. Since this time, InkSpec has continued to provide an excellent solution to providing worry free, accurate and dependable viscosity control systems that are quickly being recognized as THE industry standard!

    I’m impressed, I have to admit. Seldom do I encounter
    a blog that’s both equally educative and engaging, and without a doubt,
    you’ve hit the nail on the head. The problem is something which
    too few people are speaking intelligently about. I’m very happy that I found this in my hunt for something regarding
