For the development and the optimization of new and existent processes the IDD has a wide range of testing and analyzing methods available. This allows an accurate determination and specification of the processes and the results to accumulate a deep understanding of the underlying mechanisms.

In the field of mechanical metrology the IDD is equipped with a universal testing machine from Zwick. Using the two huge test chambers the tool is universally applicable with different adapters designed and modified by the IDD. Especially, these adapters allow the investigation of various problems ranging from mechanical stress of substrates to many aspects of the cutting technology.

All printing methods require special inks or functional fluids that possess defined physical properties. This is why the IDD built up a laboratory for fluid characterization excellently capable of investigating properties like rheological parameters, particle sizes, surface tensions, etc.

For the morphological charakterization of substrates, printing results, anilox rollers, flexo plates or similar the IDD uses standard measurement devices for printing processes and a wide range of optical (up to 100x) and tactile (AFM) microscopes. These include a profilometer that combines confocal, interferometric and atomic force microscopy in a single tool.

General tasks in the scope of measurement and control are covered by hard- and software based technology from National Instruments. This can be easily integrated into existing systems and processes.

In the context of industrial post-processing after printing, stacks of paper sheets are cut using high-speed cutters (also known as guillotine cutters). The active principles and the basic structure of a guillotine cutter have been almost unchanged since the 1930s. Thus, the related publications and examinations are old, often inadequately documented and are subject to the technical limitations of their period of origin.

In order to obtain a fundamental understanding of the applied principles of action and to develop variations or even innovations for guillotine cutters, a test rig for the determination of the cutting force was developed at the Institute of Printing Science and Technology. This emulates the industrial cutting process in a small scaled structure with very high stiffness. It is possible to reproducibly record cutting forces in 3-axis directions, the pressing force, as well as the path of the knife and the pressing bar. In addition, the angles of the guiding of the knife can be set independently of each other, and thus all four commonly used industrially types of cutting are realized, namely parallel-vertical-cut, parallel-diagonal-cut, swing-vertical-cut and swing-diagonal-cut, all having different cutting angles. The pressing beam can be clamped after the pressing (constant position), move during the cutting operation (pressing force is constant) or can be completely deactivated in order to cut without the pressing beam. For general tests, knives with different grinding angles and additional phase are available. A PXI system from National Instruments is used to control the test rig and to record the measurement data. A ZWICK Z050 material testing machine is used to power the test rig.

The test rig can be used to carry out basic investigations to understand the processes involved in cutting and pressing in the guillotine cutter, but also to carry out attempts to predict and optimize the cutting force and cutting edge quality when cutting different materials. If necessary, different knives can be used by adapters and additional measuring technology and cameras can be integrated.
