iPrint services include a measurement lab dedicated to the characterization of inks and substrates relevant to printing processes, a coating lab for first printing tests, a pre- and post-treatment labs to treat the substrate or the printed inks, two roll-to-roll pilot lines, which add to the numerous platforms that can be easily reconfigured for your needs, and simulation tools relevant to optimize printing processes. Furthermore, iPrint works in close collaboration with its spin-off Droptimize, specialized in drop watching. If you need any advice from our experts, which cover a very broad range of expertise, from print head design to post-treatment processes, iPrint’s experts are always available for consultancy.
iPrint measurement lab is equipped with all devices necessary to characterize the rheology of the inks, with a specific focus on the characterization required for the inkjet process. Furthermore, devices to characterize surface energies and layer thicknesses are available too. A non-exhaustive list of devices is: Piezo Axial Vibrator for complex viscosity measurement, Trimaster for extensional viscosity and filament break-up analyses, viscosimeters, densimeter, Keyence VHX-6000 electrical microscope, static surface tensiometer, dynamic surface tensiometer Krüss BP2, Krüss Mobile Drop for surface energy measurement, photospectrometer, four-point probe Ossila T2001A3, UVpad for UV spectrum measurement, etc.
To guarantee best support for printing development projects, iPrint is running a film application laboratory.
The professional service is about offering every single customer the individual advice needed to find the best possible solution for applications in thin film coating and printing processes by providing a recommendation for the most suitable method and system setup.
Being well equipped with state-of-the-art thin film deposition tools as spin coater, automatic film applicator, screen-printing and lamination tools the laboratory gives our process specialists the ability to verify and test process concepts immediately. Pre-treatment of substrates by corona discharge, flame or atmospheric plasma as well as curing by air, IR, UV or electron beam can be tested in the coating lab. By identifying in early project stages potential solutions for wetting, adhesion and material compatibility allows us to put our customers a step ahead of the competition.
How do you determine which pre-treatment technology is best for your application? It begins with a proper definition of your application.
An advantage of working with iPrint is our ability to test your application with an assortment of treatment technologies including air plasma, flame plasma, corona discharge and variable chemistry plasma on small to very small samples.
Each of these technologies has benefits and practical considerations. iPrint offers lab scale testing possibilities including cross-cut adhesion testing and theoretical optimization of relevant adhesion parameters like adhesion energy, interlayer tension, spreading factor and water resistance coefficient.
Similarly, iPrint also offers a lab with most of the post-treatments relevant to inkjet, as UV, NIR, oven, photonic curing (PulseForge), electron beam, to name a few.
To explore and further develop the printing process and even to combine it with traditional analogue coating methods, a pilot line is available at iPrint.
iPilMa (inkjet pilot machine) is a R2R inkjet pilot line, which allows inkjet printing at high resolution and high throughput combined with electron beam, UV or NIR curing. Speeds up to 100 m/min and web width up to 400 mm can be handled.
A team of experts offers guidance on best practices and provides a combined wealth of experience to ensure that partners get the most out of the experience and explore all of the possibilities on offer.
High quality inkjet printing relies on the perfect interplay between printing parameters and ink rheology. Droptimize, iPrint’s spin-off, supports you in reaching this goal by analyzing the ink droplets jetted by the printhead and optimizing the printing parameters accordingly.
Numerical simulation is a unique asset iPrint offers to enhance research and development within any project. It is a powerful tool to better understand subtle phenomena occurring in complex systems as well as to efficiently aid with product development.
iPrint has state of the art finite element and multiphysics capabilities such as multibody, high frequency, fluid-structure interaction, CFD and microfluidic, thermal among others. We use cutting-edge FAE packages to simulate severely non-linear, high-speed dynamic responses, which allows us to analyze the physics of inkjet printing and many other applications. Our equipment and skills allow for reliable validation and understanding of the results.
