A key factor in the growth of inkjet in these markets has been the ability to Reliability print with UV-curing inks - a technology Inks must jet reliably, printing high that was pioneered by Fujifilm. quality work for long periods with UV inkjet is a fast growing technology, minimal intervention. set to dominate these markets with its incredible productivity, quality, Consistency application range and versatility. Inks must be totally consistent, Intimate knowledge and experience producing the same high quality images of inkjet development has allowed and colours in every print and between Fujifilm to anticipate and understand the every manufactured batch. performance requirements for inkjet inks and to design products that meet them. 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.

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 dont 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 its 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 dont have the right properties can cause blockages and printhead damage (right image). </li> <li> 5.
