Paul Stinton, Technical Support Specialist at Fujifilm continues his explanation of the importance of using the right ink to avoid costly downtime and repairs to an inkjet printer. Part 1 of this two-part was first posted on Inklings April 30, 2015.

Printhead and ink supply system damage

Incompatibilities between the chemistry used in an ink and the materials used in the construction of a printhead can actually cause damage to printhead components, and the printhead literally falls apart. Likewise, damage can occur to any part of the ink supply system, from the point of entry in the machine, to the printhead. Some ink suppliers may promise better adhesion to difficult substrates, but the same aggressive chemicals they use to etch into the material can cause internal damage to the printhead and ink supply system. There is also the possibility that the materials used in the printhead or ink supply system can cause the ink to gel or pigments to fall out of dispersion, blocking the ink supply or printhead. As part of the ink development process, Fujifilm tests the compatibility of the ink with printheads, plus the components of the ink supply system in printers, to eliminate the possibility of ink incompatibility or damage. This is a time-consuming procedure, but vital to ensure ongoing machine reliability.

Ink to ink compatibility issues

If an ink with different chemistry is used in a printer, ink to ink compatibility issues can occur. Reactions between incompatible ink components can cause gelling or pigment agglomeration, which can block nozzles and the ink supply system. This is especially likely where aggressive chemicals are used in inks to obtain adhesion to difficult substrates.

All Fujifilm UV inkjet inks are produced with proprietary dispersion technology to create stable, reliable inks that are designed to work perfectly with a particular printer. The benefits of using Fujifilm UV inkjet inks are not just limited to great print quality and performance; the benefits of the care and attention put into the ink development also include increased machine up-time (from increased machine reliability and reduced maintenance), lower cost in use by eliminating the need for printhead replacement, greater productivity and reduced media wastage.

How does piezoelectric technology work?

New patented technology from Fujifilm Dimatix provides the ability to dramatically expand the number of jet actuators using a single flat piece of piezoelectric material, delivering the tremendous gains in nozzles employed and droplets of ink fired per second.
