Xerox Iridesse – After the glitter settles! Well what if? or Sure why not?!

Xerox unveiled their latest production printing press during two jam-packed events in the US and Europe. The first event took place May 9th outside Rochester, NY at the Xerox Gil Hatch Center for Customer Innovation — the largest digital print showcase in the world.

Customers, prospects and the media were invited to the unveiling of the Iridesse press and given the opportunity to kick the tires. The second reveal took place on May 23 in Warsaw, Poland during the 2018 Xerox Forum, where Xerox Premier Partners (customers) and Graphic Communication Resellers attended.

Both events could be worthy of an Oscar with the pomp and circumstance of a professional product reveal that introduced the global availability of the press.

My colleague Ralf Schlozer’s first impressions of the Iridesse, launched by Fuji Xerox last December, can be found in the post Fuji Xerox Iridesse – Two specialty colours is better than one. I invite you to re-visit Ralf’s blog for all the launch and specific details of the press while I answer the philosophical question of “do printer’s need a press like the Iridesse now that the glitter and dust have settled?”

So, if you ever worked production you know that manufacturer suggested limits are always ignored, especially if you need to get a job out or when client work is accepted in lieu of going to the competition. You see this in the offset world all the time and that is why successful print companies know that being able to configure equipment for different needs trumps equipment with a “wow” factor. Print customers first question is always can you do this, and the printer wants to respond sure, why not?! Digital equipment sometimes puts the printer into the “what if” situation. Basically, well what if we do this instead?

Quality CMYK for the most part is expected in this class of press, but in terms of flexibility, print providers expect numerous options for not only resolution but multiple halftone screens. Having the ability to respond to real time production needs based on image quality and media range gives production the flexibility to confidently accept work. Iridesse meets that challenge with Ultra HD Resolution which delivers 1200 x 1200 x 10 bit RIP resolution and 2400×2400 imaging resolution, enabling screening options from stochastic to fine line screens up to 600 dpi.

Media plays a huge role in just how many jobs and what type of work a print provider can accept. Just as in offset, digital presses must address a wide array of media while running at rated speeds. I would say most equipment manufacturers are fighting it out on this front regarding the range of media weights and types being supported. Iridesse tops out at 400gsm but gives a respectable range from 52 to 400gsm. Production flexibility comes into play when the print providers press supports a wide array of media types and weights, multiple pick points  (i.e., multiple paper trays), that allow for a broad range of supported media and media sizes along with multiple insertion options all running at rated speed. To meet these extreme requirements Xerox equipped Iridesse with technologies integrated throughout the press called “Mixed Media Xceleration”  giving the operator a wide array of run time media options with no slowdown of output.  Its this production flexibility that digital press manufacturers continue to expand upon, driving machine innovations which adds to the acceleration of the offset to digital migration and the continued ability to drive manual labor cost out of the production process. With that said, Iridesse is highly configurable, supporting many finishing scenarios from square fold to booklet making with Plockmatic’s advanced capabilities, again reducing the overall production touch points with greater production flexibility.

One could say that most digital press manufacturers are competitive in all these areas offering their own set of production capabilities, but Xerox upped the ante by making the print order of colors configurable without the need for a service technician!  As in the offset world, you just run a cleanup and change ink, or in this case you swap out the dry toner. As a PSP, you not only have the ability with Iridesse to produce 4, 5 and 6 color work, but you can self-configure which special color will underlay and overlay the CMYK opening a whole host of design capabilities for high value applications.

Xerox calls this snazzy feature “EZ Swap” which allows operators the ability to swap and run two specialty dry inks in a single pass. The key phrase is single-pass. Just imagine what you could do with a press that supports multiple pass capabilities with very accurate registration. I think offset press operators can see where I’m going with this.  Xerox has tapped into one of the last frontiers left for digital press capabilities in opening the ability for the operator to decide the dry ink lay down order with multiple specialty colors and to expand that capability with multiple passes.

Fuji Xerox Iridesse – Two specialty colours is better than one

Ralf Schlozer
 Dec 6, 2017

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.
