Fuji Xerox Iridesse – Two specialty colours is better than one

Less than a year ago, InfoTrends published a multi-client study: “Beyond CMYK: The Use of Special Effects in Digital Printing”. Not only did we find that many printers voiced a strong interest in specialty colours and the desire to have several effects as an option, they also indicated that having two specialty colour stations in the press is their preferred option.

Less than a year later, Fuji Xerox launched the Iridesse Production Press at the Fuji Xerox Premier Partner Conference on the 14th of November in Bangkok for the Asia Pacific market.

For the first time in dry toner production printing, a print engine has been equipped to print six-colours, adding two colour channels to complement process colour print with different specialty colours, including metallic, in a single pass. The Iridesse houses up to two additional specialty toners of gold, silver, clear and white, in addition to standard cyan, magenta, yellow and black. One specialty colour is in front of the CMYK units and one behind, therefore the Iridesse can underprint with one specialty colour, and overprint with another (or the same) in one pass.

Fuji Xerox also revamped toners. CMYK toners are made of Super EA Eco toner, which is Fuji Xerox’s smallest particle size toner to date, citing a particle size of 5 micron for the colour toner. The Super EA Eco toner is able to fuse quickly at a low temperature, and is able to evenly transfer six layers of toners. Another patented improvement is flat metal flakes being embedded into the metallic toner particles. The flat metallic flakes should improve the shininess of metallic prints, and some improvement over the gold toner of the Color 1000i can be noticed – although digital metallic print remains far less shiny than foiling or the like.

A unique feature of the Iridesse is being able to print hues of metallic tones in one pass, by printing silver or gold first and overprinting it with CMYK. Other toner printers would need multi-pass printing, and in offset printing each of the metallic hues would need to be mixed first. This can reduce the effort drastically in hitting metallic effects beyond plain silver or gold. The press supports metallic colours found in colour catalogues such as Pantone Metallic and Pantone Premium Metallic. By using these colour swatches, the operator can reproduce colours similar to Pantone metallic colours by simply designating the colour codes. Also, since the press offers more hues than found in the Pantone swatches, Fuji Xerox has a range of predefined metallic colours on top.
