Performance Inks must be durable, with properties When designing an ink, Fujifilm carefully such as light-fastness and physical blends a range of cosmetic, functional adhesion tailored to the specific and operational properties, combining application of the finished print. these to produce inks that are formulated for precise applications. Economy Inks must allow printers to run their operations in an efficient and cost- effective manner, providing their customers with high quality print at a reasonable price.

  • 4. UV INKJET INK TECHNOLOGYExtending the colour gamut Colour is the most important aspect of an ink. A printer needs a wide colour gamut for faithful reproduction of images and to match spot colours. Prints with rich colour have more impact and are saleable. To produce an ink with strong, vibrant colours and a wide colour gamut is theoretically simple - you just add more of the colouring pigment... ...but the challenges of inkjet are microscopic Each inkjet printhead contains hundreds of ultra-fine nozzles which are just microns wide. Any large particles in an ink can cause Pigment particles blockages in the nozzle or in other parts of the head, resulting stick together in misfiring nozzles or even printhead damage. Printheads can Colour pigment is made up of clumps of cost thousands of pounds and bad prints don’t sell. Also, to pass particles that have to be broken down through the printhead, the viscosity of the ink needs to be low. small enough to pass through an inkjet nozzle. But it’s not enough just to make the pigment clumps smaller because in a low viscosity liquid there is a tendency for the particles to agglomerate or stick back together. Pigments are also subject to gravitational settlement. A printhead at actual size. A printhead nozzle at 2500x magnification (left image) - it is just 25 microns in diameter, half the width of a human hair. Particles that are too large or don’t have the right properties can cause blockages and printhead damage (right image).

  • 7. UV INKJET INK TECHNOLOGYEvery drop mattersIn theory, inkjet technology is simple.A series of ink drops are jetted froma piezoelectric printhead onto thesubstrate beneath, without any directcontact. Tiny dots of different colouredink make up near-photographicquality images.However, the most powerful wideformat inkjet printers in the world todayuse full-width, metres-wide arrayscontaining hundreds of print heads.They jet billions of drops per second,each directed to a precise location,producing hundreds of square metres ofhigh-resolution print per hour.The demands on printheads and inkperformance are very high, but to jetwell and reliably they must be designedfor each other.Fujifilm Speciality Ink Systems partnerswith printhead manufacturers, includingits sister company, Fujifilm Dimatix,to develop optimum ink chemistryfor specific printheads. As part of thedesign process, the printhead jettingpatterns are tailored to the ink to Fujifilm ink with excellent jetting properties. Inferior ink with poor jetting performance.achieve the best performanceand reliability. These images show ink drop formation on the journey from printhead to substrate. To achieve the best image quality a printer must fire a drop at the print surface to land with pinpoint accuracy and in perfect shape. Only good ink design, tuned to the printhead, makes reliable jetting possible. UV inks are cured almost instantly by a dose of UV light. Photo-initiators in the ink react and cross link, or polymerise, forming a dry film. Because UV ink cures rapidly, printers can work quickly and economically.

UV INKJET INK TECHNOLOGYState of the art manufacturing at Broadstairs in the UKIn 2011 the Fujifilm Speciality Ink Systems manufacturing In 2013 Fujifilm made a €5m investment in a new digital inkfacility won the Best Process Plant, “Best Factory Award”. manufacturing plant and upgrade to its already considerableThis independent assessment, judged by Cranfield School R&D resources. The new premises has a footprint of 1800m2,of Management, is testament to the process controls that with the capacity to produce 6000 tonnes of digital ink a year,enable production of Fujifilm’s high quality inkjet inks. keeping Fujifilm at the forefront of UV inkjet technology. Raw materials Fujifilm works in partnership with its raw materials suppliers, ensuring that these materials meet an agreed specification. Micro-V dispersion Colour pigments are dispersed to reduce the size of particles down to less than 200nm – far smaller than a human cell. Fujifilm’s proprietary Micro-V dispersion process takes over 30 hours.
  • 10. UV INKJET INK TECHNOLOGY Mixing The pigment dispersion is blended with the other components in the formulation in massive, powerful mixing vessels capable of producing 4 tonne batches with automatic raw material feeds. Fujifilm is also expert at small batch production, with hundreds of different products being produced across its screen, narrow web and inkjet ranges. These are produced by the tonne and the manual addition of ingredients is carefully controlled by bar-coding and process control.
  • 11. Post-processing Automated filling and packingPost-processing is the final part of the Micro-V dispersion To deal with high production volumes the filling and packing process is semi-process and is designed to equalise pigment particle distribution automatic. Inks are packaged in a variety of containers from 250ml RFID taggedwithin the finished ink. This helps to reduce the likelihood of pouches and cartridges up to 10 litre packs for high productivityparticle agglomeration and settlement, optimising jetting reliability. wide format printers.Reducing the environmental impact of ink productionUnderpinning the expansion of theinkjet production facilities is Fujifilm’scommitment to the environment.
