    Expanding the boundaries with continuous inkjet
    Plenary session
    Kodak
    Vision to Reality over 50 years… Since 1967, Kodak has developed a unique variety of inkjet called Continuous Inkjet which has revolutionised the digital printing world. CIJ, with its speed and reliability was the first to bring true hybrid digital/offset printing into the mainstream. Now, 50 years later, Kodak digital presses and components, monochrome and colour, have been installed around the world in a variety of commercial, publishing, newspaper and packaging applications. Kodak CIJ is unprecedented in its speed, image quality and running cost. With a droplet generator of over 400KHz, Kodak is printing with single print arrays with Stream Inkjet Technology at speeds beyond 300 mpm and with the best production inkjet image quality, with round and uniform drops and high degree of drop placement accuracy. Due to Kodak’s nano-particulate pigment inks combined with continuous flow of ink through the nozzles, Kodak’s inks are easier to dry and can print on glossy substrates and even films and plastics with water-based inks. Now with Kodak ULTRASTREAM Inkjet Technology, customers in packaging, home décor, and industrial markets can also migrate the mainstream of their work from analogue to digital. As Kodak celebrates 50 years in the industry and the expansion of technology into the future.

    Advanced bulk piezo ceramics technology for high performance industrial inkjet printhead
    Plenary session
    Kyocera
    Most of industrial inkjet printheads are driven with piezoelectric actuator made by sintering bulk of material composition over 1000 C° or forming thin film by material deposition or sol-gel method over 600 C°. In case of bulk piezo ceramics, grain boundaries are bonded firmly through high temperature process to complete chemical reaction even in microscopic level although it requires special technology to build it into micro mechanical systems. On the other hand, thin film piezo can be applied for fine patterning but have more chance of ion migration or friction among grains due to looser grain boundary by relatively lower process temperature. Kyocera chose the bulk piezo technology as a power source of the industrial inkjet printhead due to its essential reliability, and has been optimizing the formulation as well as processes to realize high performance. Background stories of proven technology in the market are to be introduced.

    Leveraging over 30 years of printhead design, Fujifilm Dimatix continue to push the boundaries of what can be done with the technology and processes to enable piezo inkjet technology to leap forward in capabilities and performance to address the ever increased demands from the market.
    Leading the evolution of Silicon MEMS printhead development, at their in-house wafer-fab facility in Santa Clara, California, over the last 10 years Fujifilm Dimatix has delivered meaningful innovation in the technology with:
    - Sputtered PZT; to deliver exceptional nozzle life and performance stability over time
    - Nozzle level Ink recirculation; leading to increased reliability and sustainability
    - Structurally hard and robust nozzle plates; for increased resilience from head strikes
    - Durable non-wetting nozzle plate coatings; for exceptional drop ejection behavior and improved sustainability
    - Robust, chemically inert material sets; eliminating adhesive layers within the nozzle plate structure to produce a highly stable, uniform and robust monolithic structure.
    Fujifilm Dimatix will use this presentation to outline how, with the development of proprietary modeling tools and utilizing the flexibility of the MEMS manufacturing processes, has enabled Dimatix to evolve their designs to manufacture highly desirable nozzle geometries, delivering higher jet speeds, flatter frequency responses and more stable long life performance.

    Achieving industrial reliability with inkjet printing
    Inca Digital
    As inkjet printing moves into industrial manufacturing applications, reliability becomes paramount: a printer failure can immediately stop production. It is therefore important to consider at an early stage of design what factors may compromise the reliability of a printer. Once this has been done, mitigating measures can be incorporated into the design. Inkjet printers are complex systems containing many parts which are essential for the correct running of the printer. It is important to use high quality components and to put into place a scheduled maintenance regime for those components prone to wear. One of the biggest threats to a machine’s reliability is human error. It is not possible to eliminate this, but by automating routine operations, the exposure to human error can be reduced. This talk summarises some of the lessons learned at Inca Digital Printers over 17 years of developing inkjet printers for industrial applications and illustrates this with some examples.

    Contactless cleaning of printhead
    NTS Group
    Every print process requires the cleaning of the printhead. With the JetClean module the cleaning is done without touching the printhead which extends the lifetime of printhead. The automated JetClean wiping and flushing functions reduce the maintenance time and human error, increasing the printer uptime and predictable print quality.

    How to integrate UV LED curing units in printing machines for perfect polymerisation
    Hapa
    The today’s integration of a UV LED curing unit into printing machines is more like a trial and error procedure than a scientific work. The knowledge of the optical characteristic related to UV power and illumination time to the substrate are important for the design. Hapa shows and supports engineering methods for perfect designs of UV LED units for their UV curing inks. This process is important to realize low migration applications and also adhesion on different substrates.

    Pigments for inkjet food packaging printing
    BASF
    With inkjet printing showing strong and steady growth in packaging and industrial printing, there are rising concerns over the suitability and compliance of inkjet inks for sensitive applications such as food packaging, where the inks – and thereby the primary ink components like pigments, resins and additives – need to meet stringent requirements in terms of their toxicological profile and migration behaviour. This paper will review pigments for inkjet food packaging printing, in the light of the latest changes in legislations and recommendations by the competent EU national and Community authorities. A selection of suitable organic pigments for inkjet inks for food packaging printing will be presented.

    Digitising the printing process for flooring, furnishing and other functional and industrial applications
    Sensient
    Digital printing technologies are growing exponentially from mature markets such as graphic arts to strong growth areas including textiles and labels. On the back of these success stories, there is a further revolution, with digital printing being adopted as a manufacturing tool, not simply to add design or colour but as a key part in a process to get to a product. Such processes may involve deposition of functional or performance material onto a substrate within a production process. Adoption of digital printing is leading to increased efficiency, reduced waste and often more environmentally-friendly considered products. In the presentation we will discuss a few areas where digital technology is expected to play a growing role.

    New technologies to monitor pigment properties in the process and in the final product
    Microtrac
    As printhead and inkjet technology are progressing, the demand for characterisation of inks regarding their pigment size, single oversized grains and colloidal stability is increasing. The size of pigments has an impact on factors like printability, printhead blockages, sharpness of texture, optical density and colour gamut. Microtrac introduces a new technology which combines, for the first time, data from laser diffraction and Dynamic Image Analysis. This enables users to monitor the production process, to assess the final product and to detect single oversized particles or clumps which cause a risk for blockages. Furthermore, the 180° probe technology in Heterodyne Dynamic light scattering is an enabling technology for on-line and in-line applications to measure the size of nano-pigments and dyes directly in the process and in the final product with little dilution.

    Ultrasonic production of nano-size dispersions and emulsions
    Hielscher Ultrasonics
    Ultrasound is a well-established method for particle size reduction in dispersions and emulsions. Ultrasonic processors are used in the generation of nano-size material slurries, dispersions and emulsions because of the potential in the de-agglomeration and reduction of primaries. These are the mechanical effects of ultrasonic cavitation. Ultrasound can also be used to influence chemical reactions by the cavitational energy. This is sonochemistry. As the market for nano-size materials grows, the demand for ultrasonic processes at production level increases. At this stage, energy efficiency becomes important. Since the energy is required per weight or volume of processed material, the process volume links directly to the equipment size required. Therefore, the optimisation of the process efficiency is essential to reduce investment and operational costs. Furthermore, it is required to scale the lab and bench-top configurations to this final level without any variations in the process achievements. Scale up by power alone will not do this.

    Inline particle size measurement with 180° DLS
    Particle Metrix
    In many manufacturing processes of dispersions, like printing inks or inkjet inks, there is a growing demand to measure the dispersions during the production in real time. This allows a very good and energy-efficient manufacturing. Furthermore, by continuous measurement an excellent quality assurance of process and end product will be given. A common measurement method of inkjet inks is measuring the particle size of the pigment which has a direct influence on the colour. The new IPAS sensor head, can be directly integrated in the manufacturing process for particle sizing. First tests with the new IPAS sensor head have already been done and published. A sample with a size of 300 nm particle diameter was measured in an unstirred sample with the normal DLS sensor and also in a stirred sample with the IPAS sensor head. In these test measurements we can see very well that the new IPAS sensor head can now be used in moved media.

    Printing 4.0: What is the impact of the fourth industrial revolution on digital printing?
    Wifag-Polytype
    The fourth industrial revolution has generated a lot of interest and media coverage recently. Digitalisation is inherently part of the transition from conventional printing to digital printing. Due to that fact, the printing industry is probably among the most advanced sectors – at least as far as digitalisation of business processes or customer interaction (“web-to-print”) are concerned. But what about the printing machines themselves? What are the general trends in the industry and how can they be applied to a digital printing machine? How can information generated in the print shop be collected, analysed and visualised on superior systems? How can machine operators be assisted with automatic systems for job preparation or machine maintenance? What impact does variable data printing have on the overall digitalisation of a physical product? Wifag//Polytype Technologies are often confronted with these very questions and are working together with their customers to meet the demanding innovation requirements of the market.

    Semiconductor packaging is changing due to inkjet technology
    Meyer Burger
    Unlike with traditional dispense technologies, inkjet deposits a large number of very small droplets (picoliter volume) of functional liquid materials on a substrate. Thousands of individually addressable nozzles are utilised to dispense these materials in a non-contact way. The technology enables digitally patterned layers as well as homogeneous layers, even on 3D surfaces and 3D structures. Besides, in advanced semiconductor packaging, these benefits are recognised in many other industries such as printed circuit board (PCB), photovoltaics (PV), display, 3D printing and even pharmaceutics where inkjet technology finds its way into industrial manufacturing. The feature size of inkjet printing is not compatible with semiconductor front-end processes because sub-micron patterning is required. However, many wafer based back-end-of-line and strip based packaging process steps need features of tens of microns up to millimetres, and can benefit from inkjet. Therefore inkjet printing is being adopted by some of the largest semiconductor producers in the world. This paper will review the advantages of inkjet in comparison to traditional technologies, give an overview of inkjet compatible materials and highlight two application examples of the technology.

    The use of Hansen Solubility Parameters (HSP) in the development of inkjet inks
    ChemStream
    ChemStream uses Hansen Solubility Parameters in the development of inkjet inks. This lecture will demonstrate some different approaches of Hansen to successfully obtain ink stability, process performance and ink-substrate interactions. The Hansen Solubility Parameters position each molecule in the 3-dimensional ‘space of solubility’ based on 3 main characteristics: a dispersive component (D), a polar component (P), and a hydrogen bonding component (H). A solubility sphere can be defined, for each of the molecules, from which the radius is a measure of its solubility. These parameters are thus applied in the inkjet ink development process at ChemStream in order to improve nano-dispersion stability, material compatibility, ink-media interactions etc.

    Multi-purpose picodrop dosing system for fast and easy testing of ink-substrate interactions and printing behaviour
    Dataphysics
    In order to study printing behaviour, it is advisable to emulate the printing process as far as possible which means in particular that a “printer-like” dispensing system should be used. DataPhysics provides such a dispensing system, namely the picodrop dosing system PDDS, which has originally been developed for contact angle measurement on very small testing spots. The PDDS is able to dispense liquid droplets of down to 30 pl – which is obviously well in the range of droplets created by inkjet printheads. Moreover, the PDDS dispenses these droplets via acoustic pulses with frequencies of up to 10000 Hz such that the system indeed perfectly simulates a printer head. Of course, varying the amplitude and width of the piezo-pulses allows to modify the dispensed drop volume. Hence, fast and reliable contact angle measurements for the testing of ink-substrate interactions are easily possible.

    3D jet straightness analysis by image analysis in different focal planes
    Prof. Fritz Bircher, Lionel Buzzetti
    iPrint
    One of the most important jetting properties of high quality inkjet printing systems is the jet straightness of the printheads. Dependent on the used printhead the total deviation of printed dots has a systematic error part which can be related mainly to jet straightness errors and a stochastic part that is usually smaller in magnitude. If the average jet straightness errors of a printhead are known, the total printed dot positon errors can be reduced to the level of stochastic errors by software compensation in multiple passes. Current systems to measure the jet straightness in three coordinates (e.g. print direction, cross-print direction and distance from the nozzle plate) need to scan the printhead nozzle by nozzle with two 90° oriented cameras which is in terms of measurement duration impractical for integration in industrial print machines. With a system that analyses droplets of multiple nozzles in different parallel focal planes, the actual positions and velocities in 3D of all seen droplets can be measured simultaneously by either analysing the sharpness function of drops (similar to focus systems in mobile phone cameras) or by measuring the change in magnification with a non-telecentric lens and double flashing. As jet straightness measurements of multiple nozzles can be carried out in parallel the total time to assess a complete printhead can be reduced significantly. As such a system can operate from a single viewpoint, integration in print machines is simplified and by analysing in the printing gap continuous measurement during printing is possible.

    Inkjet printing for control of pharmaceutical polymorphism
    University College London
    Polymorph selection of pharmaceuticals is critical for the performance and stability of medicines. In order to select the most appropriate polymorph for development, it is vital to be able to screen, isolate and characterise metastable crystalline forms. Inkjet printing offers much potential in this area, because the small volumes of drug solutions that can be jetted mean crystallisation occurs rapidly and in volumetric confinement. Here, the use of inkjet printing to isolate metastable forms of a number of pharmaceuticals will be discussed. Methods of characterisation of the printed crystals, including Raman spectroscopy and X-ray diffraction, will also be introduced.

    Inkjet printing for micro particle fabrication for the incorporation of multiple drugs
    Vanderbilt University
    Conventional micro particle fabrication methods result in particles that are not precise in size yielding unpredictable drug release kinetics and drug distribution throughout the body. We demonstrate the strength of piezoelectric inkjet printing to prepare precise micro particles for drug delivery applications overcoming the drawbacks of conventional fabrication methods. The technique involves the printing of droplets containing polymer compositions that are capable to undergo a crosslinking process using UV light. These droplets contain drug molecules which are entrapped into the micro particles after the crosslinking process. In another strategy, we print droplets of polymer precursors, which are crosslinked as well in a post-printing process. Details and conditions of this scalable process and the introduction of drug molecules in high loading capacities are presented in the lecture.

    Prevention of inkjet nozzle clogging
    Soliton/PSS
    A common cause of failure in inkjet printing is clogging of the jet nozzle by oversized pigment or foreign large particulates. Manufacturers are always looking for changes in formulation, production, and QC to ensure that the ink will pass through nozzles without blockage. Many techniques are available for sizing particles, but most only provide information on size and relative concentration, not absolute concentration. Single Particle Optical Sizing, SPOS, sizes and counts each particle that passes through the detection zone, providing much a higher resolution and quantitative accuracy than most calculated methods, allowing for significant improvements in final product. A brief introduction to the SPOS technique will be presented, followed by examples of measurements made on a variety of inkjet inks at various stages of processing, showing how this data can be used to improve inks from the formulation stage, through production, and ultimately to the printed product.

    Making digital technologies accessible for textile SMEs
    TexZeppelin
    The rapid development of digital printing technologies has transformed textile printing and created vibrant business opportunities by leveraging many new trends and technologies on the level of software, hardware and inkjet inks. Existing and starting SME-companies explore the latest digital textile and garment printing technologies that enhance their competitiveness. However, there are still a lot of challenges to overcome to benefit fully of the many advantages inherently linked to digital technologies. Bottleneck, especially for SMEs, is actually their dependence on external commission finishers for the ready-to-print textile and for functional post treatments (read: repellency, antimicrobial…) slowing down the production chain. Moreover, this dependence inhibits their huge business potential. This lecture focuses on many actual and future developments in digital technologies and on different issues such as in-line pretreatments and digital finishing/coating which make in-house production possible. Also digital dyeing is an actual issue for many SMEs.

    Widening the window: Powerdrop’s approach to opening up inkjet
    Plenary session
    Archipelago Technology
    The last five years have seen great advances in inkjet and the arrival of MEMS based heads is heralding the next stage in inkjet evolution. However, modern inkjet printheads require specialised inks which do not by themselves deliver everything that customers require in terms of physical robustness and flexibility. Archipelago’s Powerdrop technology has been created to complement inkjet and lay down functional materials that both widen substrate latitude and improve the final appearance and robustness of the image. The Powerdrop print drum can eject many sticky and viscous functional materials such as UV varnish, corrosive pre-coats and even hot melt adhesives. In this talk, Dan Mace, Archipelago’s COO, will update you on the latest developments and explain how Powerdrop can greatly expand the applications for large scale inkjet and industrial printing.

    New print mode developments for high productivity and laydown using Xaar printheads
    Plenary session
    Xaar
    Previously reported was the capability of Xaar’s Platform 3 printheads incorporating short channel, double ended actuators and Xaar’s TF Technology® to achieve high productivity printing. Xaar has now developed a number of patented printing modes which significantly increase the productivity over its standard ‘3-cycle’ mode printing. The new modes of operation increase productivity and laydown by more than 5 times and enable these printheads to offer benefits for a number of applications such as printing of ‘special effects’, Braille and 3D printing. Details of the new printing modes will be discussed.

    What can one print sector learn from another when it comes to inkjet implementation? Today the graphic arts sector is exploiting the real benefits that only inkjet can add by creating special effects and variability. But when inkjet was first introduced most print shops used their press as a short-run offset device. Print shops in the labelling sector see it the same way. Expect packaging to as well. It’s nearly 20 years since Harlequin® was first used in an inkjet production press and eight years since the ultra-high-speed HP PageWide web presses shipped with Harlequin in their Digital Front End. So Global Graphics has the long view of what you might expect to learn from other sectors be it their similarities or their differences.

    Digital coatings: Markets and technologies
    TTP
    Three technology groups exist to address established markets for digital decoration and marking: drop on demand inkjet, continuous inkjet and valve jet. These technologies occupy very different capability spaces in terms of drop size (and hence image resolution), firing frequency (and hence throughput) and fluid rheology. They serve the needs of most decoration and coding markets well. End users requiring viscous or particulate-laden fluids to be deposited digitally are being held back however. Emerging markets that fit this profile include additive manufacturing, adhesives for garment and footwear manufacturing, functional coatings for textiles, flooring and furniture, automotive and aerospace painting, security printing, bio-printing and high quality metallic decoration of packaging. Technologies that can operate in this space include TTP’s Vista and Touchspray printheads, Archipelago’s Powercoat, and Alchemie’s Jetronica. This talk will examine both the markets mentioned and the technologies offered, concluding that we are seeing the emergence of a new category of inkjet device for functional printing.

    Filtration, degassing and oxygen measurement technologies for inkjet printing applications
    Pall
    Filtration and degasification are key technology requirements for digital printing. Finer resolution and higher printing speed as well as changing ink chemistries and substrates are the challenging factors of today. Controlling of further parameters like dissolved oxygen become more important. This presentation will provide an overview of the filtration and degassing methodology and technology on board of digital ink jet printers, including specific product type recommendations and how to ensure keeping parameters under control.
    Advantage of DO-measurement in the lab and online on board of the printer
    UMS
    Fast printing heads demand precise conditioning of ink. A low dissolved oxygen level is one of the major characteristics of an appropriate conditioned printing ink. For 15 years, UMS has been offering proven and easy to handle oxygen sensors and meters for the printing industry. The presentation will show some measuring tools and will explain how to use them.

    Instantaneous and low thermal stress inkjet post-processing
    Adphos
    A large variety of inkjet applications, especially according to component geometries, substrate materials and coating types are justifying the attractive market potential of the non-contacting inkjet-technology. But today most limitations result from the necessary post-processing – the drying step – of the liquid jetted coating pattern. In this presentation, it is outlined, how an instantaneous and low thermal stress drying technology – the adphosNIR® systems technology – can overcome the limitations. Based on real case application examples, special working principles of the adphosNIR®-technology are demonstrated, as well as its unique benefits in textile, plastics, cardboards, biomaterials, printed electronics and now also in direct print-to-shape inkjet applications in comparison with conventional drying solutions.

    Brand colour communication in digital printing workflows
    ColorGATE
    The consideration of brand colour communication is critical for a growing amount of print products that are being produced by digital printing systems. Most prominently this is the package printing market with corrugated card boards and folding cartons, as well as labels and direct to object printing. The transition from analogue to digital printing for such packaging applications requires to master the challenges of reproducing brand colours with a given process colour ink combination, rather than deploying a specifically mixed spot ink to match a specified spot colour. Gamut extended ink sets improve the general colour capabilities in order to reproduce a spot colour but also need specific attention and control. The speaker is outlining alternative approaches how to master these challenges.

    Recent experimental advances in characterising inks and substrates optimising inkjet processes and ink adhesion
    Krüss
    Inkjet printing processes are governed by the solid-liquid interactions between ink and nozzle and ink and substrate. In particular, due to the large range of very different substrates, a proper adjustment of the ink to the substrate properties is important to ensure a proper print image preventing e.g. fuzzy images due to excessive drop spreading or Marangoni-effect driven coffee stain effects. We will explain and illustrate on customer examples, how state-of-the-art dynamic surface tension and picoliter sessile drop contact angle measurements help to adjust inks to certain printing processes. In addition, we provide ideas how interfacial rheology measurements can be useful to gain insight into Marangoni flows during evaporation. Also, considering the polar and disperse parts of the inks’ surface tension and the substrates’ surface free energy can help significantly optimising not only the print image, but also the durability, i.e. long term stability of a particular ink-substrate pairing, as will be illustrated in this presentation. Further, we will demonstrate on the example of polyethylene and polypropylene when and why test-inks (i.e. dyne pens) fail to monitor the efficiency of plasma and/or corona pre-treatments and how modern contact angle measurements can prevent substrate overtreatment and thus assuring best durability of a coating. In this context, we will also illustrate how the recently patented liquid needle dosing technique facilitates high speed contact angle measurements, in that possible error sources still present in traditional contact angle techniques are intrinsically excluded and thereby provide substrate’s surface free energy data of highest reproducibility and best comparability combined with greatest ease-of use.

    The evolution of UV-LED curing: Where next?
    Integration Technology
    With increasing efficiencies, higher installed base and new application fields, UV-LED is the shooting star of curing technologies. As the technology evolves available power of UV-LEDs is no longer the limiting factor of the curing systems. With powers exceeding 30W/cm² at 395nm, the demand for variability, size and cooling become stronger and stronger. We will have a look at the new demands to a UV-LED system regarding optimised yield, efficiency, modularity as well as the preparation for industry 4.0.

    Development of high quality inks and fluids, printers, and printheads requires state-of-the-art characterisation equipment and techniques. It is vital to understand how the developed ink actually behaves, both on ejection from the printhead and when landing onto the substrate of choice. We will provide an excellent introduction to these essential areas of study, including basic considerations for ink and waveform design, as well as important tests used to verify the performance of a new ink. We will also provide a survey of the key equipment that makes up a test printing rig, including drop watcher, ink supply, printhead, print controller, mist extractor, and belt or linear stage, for creating test and sample prints.

    Advances in water based ink solutions
    Kao Collins
    There has always been a desire to substitute water based printing solutions for solvent based solutions. Water is inexpensive, odourless and safe. That desire has only increased as companies look for ways to become more environmentally friendly. Thankfully a range of new polymeric encapsulated pigment dispersions are allowing ink formulators to push the boundaries of inkjet inks. These non-hazardous, non-reactive inks are now able to print high quality robust images onto, among other things, non-absorptive substrates. Those inks when used in conjunction with rapidly developing printhead technology and drying/curing technology are opening new markets and opportunities for inkjet printing including, among other things, flexible packaging for the food and pharmaceutical industries. This presentation explains some of the recent advancements in inkjet inks with a special focus on some of these new pigment dispersions.

    Revolution of T-shirt printing
    Matsui
    We will show a comparison between “Collaboration of screen printing and inkjet printing” and “PVC Plastisol printing”. PVC Plastisol has good printability because it will not get clogged and is easy to colour match by using a colour matching system. However, we believe that screen + inkjet printing could be even better than PVC Plastisol printing in terms of printability and colour matching. Also, screen + inkjet printing will not have issues that PVC Plastisol printing does, such as hard hand-feel, not ecological, or cracks etc. The productability of screen + inkjet printing has also improved, it now can print 450 shirts per hour. In our presentation, we can show the comparison between those two types of printing in detail.

    Inkjet waveform optimisation by meniscus motion analysis
    iPrint
    Waveform optimisation is a key to success for piezo drop on demand printing systems. The industry-established method for waveform analysis and optimisation is a drop watching analysis. With a drop watching system, usually a large number of droplets has to be jetted for each configuration of the printing system. As inkjet is increasingly being used in functional printing, an increasing number of fluids with a certain toxicity, limited stability or very high material cost are jetted. For such applications there is a need to reduce the amount of wasted fluid. One way to accomplish this is the analysis of the meniscus motion. If a waveform is proportionally scaled down to an amplitude that does not generate drops, acoustic timing can be analysed and optimised by analysing the meniscus motion. An estimation of the frequency – velocity variation can be obtained by analysis of the meniscus motion in the range of actual jetting frequencies. By analysing meniscus oscillations at different pulse amplitudes that are below the drop emission threshold, the voltage necessary to reach a certain drop speed could be estimated. As the same setup as for drop watching analysis can be used for the analysis of meniscus motion, implementation of such an analysis in existing systems is expected to be efficient.
