Hi I have been experimenting with some of the printed shirts on my kornit. After drying the printed shirt, the print sometimes feels tacky, but doesnt smell of the fixation spray. If I rub the print with my fingernail, the print will eventually start coming off. But, I run it through the dryer again, it no longer feels tacky, but I am still able to rub the ink off. Does anyone have any ideas or suggestions.
Thanks

wait for 24hours en then feel again.
The print have to dry in also after curing.

It also depends on the substrate...

Are you using a gas or electric dryer? The shirt is NOT cured. How long is your shirt in the oven and what temperature are you at?

It's a dryer thing most likely. Potentially slow down the belt. And if the shirt has any poly in it, that can be an issue.

I am having the same problem here.

me too. the producer of the t-shirts (Roly) is saying there isn't any poly in it. but the scratch make the color vanish (I mean, normal scratch, not heavy), expecially in areas where the black is printed without any percentage of white under the black zone.

When water is not vaporized 100% it will do that. Not because of heat it is from less air flow. I had same issue with my Niagara 6(cabinet dryer). Increase hot air flow to the max with correct temp in dryer.
Cheers! Beers are on me always.

My thoughts are the same as the people above, curing. Loads of info out there on dwell time and temperature. ALSO, is it possible you are using too much pretreatment in order to make the print look brighter? Too much pretreatment can create to much of a barrier between the shirt and the ink which will not allow the ink to bond with the fibers of the shirt while drying. Or you could be laying down to much white ink. Backing off the white % in the art or single white instead of double white can help.
