really? hovering was the only difference? i've never really seen a difference when i hovered, but maybe i need to take a closer look!
Yes, it happened with the IA as well - interestingly, the IA had more trouble with the pitting than the Dupont (although it could have been a difference in application qty.) The garments were black hoodies (Hanes 100% cotton and Gildan 80/20.)I know what you mean about "ink being shrunk by the heat of the cure" This is what was happening to me with Cotton Heritage 1080 shirts. Even if I tried a short 90 second cure the white ink would seem to shrink, or cure above the shirt, not with the shirt. If I pulled it, it would crack and come off easily. It was a very solid print though, no pitting. Still not sure what was causing it. I attributed it to being the shirt's fault so I stopped using them.
So that happened to you with IA pretreat also? What brand of shirt?
thanks for your reply. I believe you are referring to shaking the white inks? Sorry I should have been specific, but I was asking about the shaking of the dampers...it's quite easy to just do it every morning, and make it a part of your routine. i typically only agitate my white ink every other day or so. i've gone longer, but i would still recommend a daily routine.
it's possible, but not too likely if you maintain the dampers properly. i wrote a thread in the NeoFlex section regarding damper maintenance. i change out my 4 white ink dampers every 3-4 weeks.So the TiO2 slowly settles out of suspension in the ink... I assume that stuff sort of "piles up" like super fine sand in the damper right? If that happens too much, I can only guess the damper must just clog up. Can that TiO2 sludge get beyond the damper and clog the nozzles?
