I too own an
DTG Kiosk 2 and it sounds like your print head could need replacing or your machine is not draining your ink or you graphic output has a pink tint to it.
I remember when i first got my Kiosk I could print all these other images ok but when I kept printing this one image I created instead of a bright yellow colour coming out an green yellowish colour came out instead. I checked my monitor and the image looked yellow. After wasting 12 t-shirts with this image a friend of mine did something in photoshop that shows you what colour your image is made up off and there it was my yellow had a green tint in it.
so if your
dtg printer is printing other images good, maybe the one image you printing may have a slight pink tint in it or you need to replace your print head or your caping station could not be draining.
hope that helps.
