Arizona Printer Inks as of 2015
Introduction
Your Océ Arizona printer uses four types of UV-curable inks, referred to as Océ IJC255, Océ
IJC256, Océ IJC257, and Océ IJC258. These inks require daily maintenance with a vacuum suction
device and a weekly physical cleaning (swabbing) of the printheads. The Océ IJC255 White ink
and all of the Océ IJC256, IJC257, and IJC258 inks require small jetting actions ("spitting")
between printing times to keep the printheads in a ready-to-print state. This spitting action
amounts to very little ink usage but does require that the user clean the maintenance tray covers
more frequently. All ink types include Cyan, Magenta, Yellow, Black, and for printers with the
option installed, White or Varnish. Due to the UV curing technology, the ink dries immediately,
but most curing takes time. Most of the curing occurs in the first 24 hours, but it can take up to 72
hours to cure fully. In most cases, the printed material may be handled or cut directly after
printing.
When printing with these inks, imaging results will be different, - not necessarily better or worse,
but always different. If you want to change from one ink type to another we recommend that you
consult with an Application Specialist. There are many variables, such as media, that determine
the suitability of an ink to your working methods and output needs. An application Specialist will
help you to make the best decisions.
Océ IJC255 UV Curable Inks
This ink set is characterized by a superior color gamut, a semi-gloss appearance and a very hard
surface finish. IJC255 is the ink of choice for paper and paper-capped rigid media for close viewed
POP/POS applications when only the best print quality is acceptable. Adhesion to many media is
not as good as with the other IJC25x inks.
Océ IJC2256 UV Curable Inks
This ink set is characterized by an excellent color gamut, satin appearance and a slightly softer
surface finish. IJC256 is the ink of choice for vinyl and foamed, rigid media applications when
excellent print quality and automated finishing operations are required.
Océ IJC256 has lower dot gain characteristics than Océ IJC255. As a result, there is the potential
for more structure and streaking in solid colors and for more image artifacts in areas of heavy
coverage (dark colors) with the new formulation. This is especially apparent on many paper-
based media used for most indoor applications such as foam board, corrugated cardboard, card
stock and poster paper. Océ IJC256 inks also have a softer surface when cured and printed
materials are less scratch and smudge resistant. Océ IJC256 inks feel slightly "tacky" when cured
and have a more satin finished appearance when compared to the semi-gloss finish of Océ
IJC255 inks. This can be a benefit to distant-viewed applications where glare, caused by the semi-
gloss finish of the original Océ IJC255 inks, can be a visual distraction. This particular
characteristic is highly subjective.
Océ IJC257 UV Curable Inks
Offer improved adhesion function over IJC256 (and IJC255) on a wide range of media, but with
similar color strength and cosmetic appearance. The IJC257 ink set is characterized by an
excellent color gamut, satin-matte appearance and a medium-hard surface finish. It's primary
advantage over IJC256 is that is offers improved adhesion function to a wider range of indoor
and outdoor media. IJC257 is the ink of choice for general graphics applications on rigid or
flexible media when excellent print quality, large color gamut and good adhesion function are
required.
