Non Plastisol inks for nylon/poly?
« on: July 30, 2015, 10:26:07 AM »
I print a fair amount of polyester/nylon jackets and bags, mostly bags, drawstring packs/duffles and many times am printing white inks onto darks.  I have always used plastisol, but would like an alternative as some of the products do not fit down the dryer well and they almost always have issues with heat.  I have looked around but never inquired past my web searching.  Just looking for maybe a solvent based for this application that will air dry or use very low heat and get a full durable cure.  Any insight is appreciated, thanks in advance!

look at Nazdar's offerings. Their tech help is great as well.
However, take it from somone who knows, air dry inks can pose new problems for space to put the various items while drying.(umbrellas for instance)
It's why I dropped flat stock in my small workspace, and that stuff uses relatively compact drying racks.

When there is shrinkage problems. We flash it or bake it up to 90C then heat press it for a minimums 10 or 15 secs depending on the thickness of the ink.

I am already adding 4% of the IC Low Cure Add. into my mix and running the dryer at 290 so I am getting to 280 to 285 at dryer exit, that is the best case scenario I am using with plastisol.  Just not sure if that is my best case scenario period, or if there is something better. 

As frog stated, changing inks may cure one ill but cause 3 more.

A compromise could be a catalyzed ink that is flashed just enough to not offset, and then can be loosely stacked to fully cure
