Discuss the various aspects of direct to garment printing. DTG printers include Brother, T-Jet, Flexi-Jet, DTG Kiosk, Kornit, Mimaki, Tex-Jet and others! Discuss and learn about this up and coming printing technology.
I just wanted to pose a question for anyone else who is also curious, and let everyone know of my experiment with the pre-treatment solution for DTG black printing. What exactly is in this dupont branded treatment, judging by the smell I think it's elmer's glue and water, with a bit of formaldehyde.
I was going to do a little experiment with that and see what I can come up with, I'd imagine anything that is capable of "stiffining" the fabric enough to make sure the white ink lays on top will work. Any other input on this? Does anyone know what's actually in the stuff?
I had a friend that sold cleaning products to company's like Frito-Lay and other company's, what he would do is get a sample and send it to a lab to analyze, with the formula he would have it duplicated by a chemical company and sell it cheaper.

I heard an airbrusher talking about a pretreatment spray they used to keep the fibers down. They spray it on and heat press the shirt, then airbrush. I dont know what the stuff is called as this was a while back. Im also not sure if it would work with white ink because Im have heard the pretreatment and white ink form some sort of bond together kinda like JB Weld...but I dont know for certain. Maybe someone else can jump in and verify or deny this as Im curious as well. If that is the case, stiffening the fabric probably wouldnt cut it for white ink printing. Maybe for lights, but that form of pretreat is not priced too bad IMO.
It definately has a component that bonds the white ink to the fabric. simply stiffening the fabric is not going to bind it. There is an agent in the pretreatment itself that binds the ink to the fabric.

I was told that Dupont actually has the patent on some of the items in the pretreatment. Thus the reason why we have not seen other companies with a formula that works as well as Dupont. Not sure if this is correct though. The rumors are that the new pretreatment formula from Dupont that is coming out in a couple of months is even better (less stains, easier to apply,...). Can't wait to see the results myself.
......... judging by the smell I think it's elmer's glue and water, with a bit of formaldehyde.
LOL wouldn't that be great.

And did you see any enhancement, Don? Does it leave less stains and less square? Does it have more tolerance regarding the quantity you drop? Maybe better white adhesion?
Assuming that the shipping product is the same as that which we sampled, yes, it is more "forgiving" on the overspray side and no it doesn't leave as noticeable a residue. Our testing also showed that it did not "yellow" on lighter garments like the older one occasionally did.

Thanks and best regards,

We have found that the new formulation white pretreatment we're now shipping gives you a brighter white and we've also noticed a significant reduction in hand on the print.
If you have ever hit a print head on a pretreated black shirt you definately understand how well the white ink "bonds" with the pretreatment. We tried chemicals that were eating up our rubber gloves but still wouldn't unclog the print head.
"We have found that the new formulation white pretreatment........."
Harry, is this the "new" official product that is designed for Dupont inks? We alwas hear the rumors, but I know no-one wants to be stuck with old has been stuff....
