Gandinnovations Jeti 3324 AquaJet dye sublimation direct to fabric printer

Every ink set, every ink chemistry favors some colors. With the AquaJet the ink is being sublimated, so what you first see on the textile is not the same as the lovely colors that pop out after heat sublimation. The best colors of the AquaJet can be bright reds, bright greens, blues. This system produces good skin colors. The image of the colored chameleon on their test print are excellent.

If the image you are printing is pure graphic design (in other words, not a photograph) you can often make it look better on fabric than you could a photograph. With a photograph often the shadows will lose detail because of the inherent nature of the heavy ink saturation that are needed for textiles.

But if your image is a photograph, it can also turn out gorgeous on a textile printer such as the AquaJet if the photograph is not filled with shadow areas. Thus the downside is that dark colors may get too dark, unless your graphic designer and/or photographer know this in advance.

Most dye sublimation machines are at entry level. This Gandinnovations Jeti 3324 AquaJet direct to textile dye sublimation is a robust grand-format sized production printer intended for round the clock production. You may notice the heavy-duty fabric feeding rollers have ribs in their rubber-like surface. This is a new trend that I have seen in grand format inkjet printers.

Just realize that most analysts and specialists suggest that you tend to get brighter color with dye sublimation ink onto transfer paper and then use a calendaring heat press. Downside is the added cost of the heat press (but the results are much brighter colors).

Gandinnovations Jeti 3324 AquaJet: a work in progress.

At one trade show late 2008 I was told that several aspects of the AquaJet were “new”, suggesting that something on the earlier version of the printer had needed to be completely redesigned. When I visited the factory in summer 2008 they were in the process of finishing changing the entire supplementary unit that stands to one side. So clearly during most of 2008 this printer was still being worked on, and retrofitted. I would assume that anyone who was brave and bought an early version has had it upgraded by retrofitting to replace the first components which were experimental.

The AquaJet then in 2009 was improved over the series of issues and glitches since it was first developed during 2007-2008, so buying a used model from someone would not be a good idea. For example, evidently in Germany there were issues with early versions. This is true of most brands and models: the first production out the door is often still really in beta stage. Only after a year or so is a complex printer closer to being mature.

Be wary of “Success Stories” that are popular in trade magazines. These rarely admit any downsides of a printer and praise everything about the printer (this is for all brands and all models). Success Stories tend, usually, to be unrealistic: Just look at the Success Stories for the DuPont UV printers: these printers were so bad that even DuPont dropped them!. But the Success Story in the trade magazine praised and praised this Chinese-made UV printer. Why did they not tell anyone that 75% of the first production run had to be recalled and junked (yes, in landfill).

And while in the cautious mode and while mentioning DuPont, be very wary of buying any used DuPont Artistri textile printer with dual carriages. Even their distributors said these had potential issues (they produced wonderful colors with POP, but were a bit finicky and thus required TWO operators to run them: one at the front, one at the back!). That makes operational costs a bit pricy.

Essential before deciding on any brand or model: find (on your own) a printshop that already has the printer you are interested in. Ask the owner and also (separately!) ask the printer operator. In every printshop around the world, the comments by an owner, by a manager, and by the printer operator are a bit difference with respect to pros and cons of any printer.

Recently Nicholas Hellmuth spent some days inside a Gandinnovations Factory. Here is inspecting the Jeti 3324 AquaJet.

Dye sublimation is for inkjet printers; thermal dye transfer is for desktop sized photo printers

Do not confuse “dye sub” with “thermal dye transfer.” Many desktop photo printers use “dye sub” chemistry, but these are thermal dye transfer ink systems. If the printer uses wax-based ribbons, then it is thermal dye transfer. Kodak, Sony, and other companies make these. Matan had the only wide-format thermal dye transfer printer (Matan Sprinter for example).

Dye sublimation inkjet printing utilizes heating to sublimate the ink.

Dye sub means the ink is turned into its full brilliance and saturated color after the application of heat. The heat turns the disperse dye ink into a gas and fixes it in or on top of the material you wish to decorate.

There are two ways to do this: print on transfer paper and sublimate the ink OFF the transfer paper onto the end-product (some kind of a polyester material, or metal coated with polyester if you wish to print onto aluminum or tiles or whatever). Obviously dye sublimation onto hard rigid materials is done with a flatbed heat press. To sublimate banner or billboard sized material you would normally use a calendering machine. This is how the first-generation Gandinnovations dye sub printer system worked.

The second way to sublimate is direct sublimation with disperse dye ink. This is done by placing a heater unit directly onto the front of the printer. This is how the new generation of AquaJet handles the sublimation.

The advantage of inkjet sublimation is that you don't see the dot structure of the droplets; the sublimation process creates a better image with no evidence of inkjet nozzle technology. You get continuous tone, as in a real old-fashioned photograph. The downside, however, is that you can sublimate only onto a polyester fabric or onto other materials with a polyester receiver coating. Just realize that this is a dye ink, and not intended to last for eternity.

The best way to learn about dye sublimation is to visit SGIA or VISCOM Italy or FESPA trade shows. Or visit DigiFab in Los Angeles or New York, or the Yuhan-Kimberly distributors around the world.

Alternatives and Options

Since there is an economic recession these days, it is a time when printshop owners and managers spend more time checking the pros and cons of a printer. Plus, printshop owners tell me that they want to have a viable short list of pertinent competing models so they can be absolutely sure that the model they select is the best for their printshop and their clients.

VUTEk and HP Scitex both have a clever switch-over system. In this manner you can print with solvent inks Monday through Wednesday, and then print with dye-sublimation inks Thursday and Friday. This requires a special solvent-based dye sub ink in order that the ink can flow through the same lines that previously held full-strength normal solvent inks.

But with the increased competition in the soft signage business, people are also looking for unique printers, such as a model that has 8 colors or 12 colors. Yuhan-Kimberly offers both. Yuhan is the Korean branch of Kimberly-Clark. So this company is financially solid and can afford to create and maintain good quality. I have been to their factory twice. They make several textile ink chemistries themselves and know enough about textile ink to test and select the best of those chemistries that they do not make themselves. The 12-color printer is the VU-180 ; this is not UV-cured; it is a grand format textile printer.

What's up for 2009 and new in 2010

I am under NDA on the next wave of grand format textile printers, but there will be some surprises by 2011. But if you need your printer now, today, then don't wait. Compare and contrast the various offerings (such as the DigiFab StampaJet ). Also realize that you can print on a variety of soft signage materials with the Durst Rho 320R and Rho 351R (these are both UV-cured). In

There are FLAAR Reports on all the Yuhan, DigiFab, and Rho textile printers. Our initial inspection of the Eurotech Mermaid direct-to-fabric disperse dye sublimation 3.2 meter printer was earlier in 2009; it was still in prototype stage. Now the printer has advanced through alpha stage into beta stage but I have not inspected it in any actual printshop.

In the meantime Durst has launched their entry into the 3.2 meter soft-signage market, the Durst Rhotex.
