Rheology measurements are a major factor in the development and production of printing inks, raw materials for inks and other pasty liquids. Important factors for offset printing inks are tack (or stickiness of the ink), water pick-up, water release and viscosity.
To ensure a consistent quality of an ink, IGT Testing Systems has developed a serie of devices to measure in an efficient, relaible and reproducible way, some of the rheological proporties of offset printing inks and related materials. All devices are fully computer controlled.
The fields of application are Quality Control, Research and Development and troubleshooting. Because of the high repeatability and reproducibility of measurments bij the IGT tack devices, these are widely used by companies at an international level. The measured tack values can be relaible exchanged between facilities to ensure a homogeneous quality thoughout the world.
IGT tack testers are used on:
- Printing ink industry
- Security printers
- Paper mills
- Pigment-, Resin- and Varnish industry
- Chemical industry
- Raw materials
- Training Centres
- Research Institutes
