We have spent a good bit of time exploring this product. We have been told it is a must and they highly suggest using gas, not electric.
The reason is pretty clear in my mind. When it prints it really wets the shirt up quite a bit and there needs to be a decent dwell time in the drying time in order to cure and dry the ink on the shirt. A real key is the air movement inside the tunnel that makes the process work properly.
We have a Kornit and have been using a heat press until our dryer arrives into the country. We've found it ok but occasionally we get white dots appearing through the print. Also ribbed Tshirts dont turn out well using a heat press. We were also told that a gas dryer is best. Apparantly it distributes the heat more evenly.
speaking from your experience ,with the small 932d, how many light / dark T-shirts can it print(4-6colors) in an hour ,realistically? Since we hv lots of small runs ,1-10 , im wondering if it is cost effective for us to own one! thx!
I have owned a 931 Kornit for 1 year now. When I first purchased it my gas dryer wasn't available yet so we used an electric dryer with no luck. It just didn't cure the ink. I am not sure about the 932, but the 931 can print about 30 dark garments or 80 white garments per hour.
You need the gas dryer to evaporate the IPA spray, and at least an 8ft oven to boot. The solivent inks take a long time to dry, over 2mins. And we find a gas dryer keeps the shirts from drying out, the gas emits a moisture inside the oven, our shirts come out nice and flat , almost pressed looking, not dry and filled with static. Plus you'll never scorched a shirt.
I currently have an 8' Interchange dryer for my 931 using water based ink. We have found that at times 8' isn't enough so I have ordered an additional 4' for heat chamber to solve any drying issues. I have also had to construct vented hoods for each end of the dryer so the fumes get vented rather than flow out to the plant.
we have been using a slightly modified (by hix) 3616 in their premiere series. It is electric and we have had zero returns for washability. We test by adding an extra shirt to many orders to keep an eye on it. The shirt will have a certain smell to it if not cured properly. Dialing in the dryer was very important in our opinion.
That is just our experience with a 932DS over the last 3 months.
question on Kornit 932D - can you cure with a heat press?
