If possible, I would move the printer into a small room where you can use a humidifer to regulate the humidity. Otherwise, I have seen several
dtg owners build a small plastic room using plastic tarps. I think Justin Walker has posted some pictures of what he did with his Kornit. If your humidity is going to stay that low and you want to print white ink, then you are going to have problems with any
dtg printer in my opinion. Just part of the fun you deal with when you are printing with white ink.
Winter weather is going to come soon and you are going to see the number of posts concerning white ink clogging is going to rise. It happens every year and it has to do with using heaters will dry the air out. Regulating humidity is a key to white ink printing.
Good luck with your decision,
Mark
